(#24111)
alternative to #24101
#23892 changed the opensym experimental switch so that it has to be
enabled in the context of the generic/template declarations capturing
the symbols, not the context of the instantiation of the
generics/templates. This was to be in line with where the compiler gives
the warnings and changes behavior in a potentially breaking way.
However `results` [depends on the old
behavior](https://github.com/arnetheduck/nim-results/blob/71d404b314479a6205bfd050f4fe5fe49cdafc69/results.nim#L1428),
so that the callers of the macros provided by results always take
advantage of the opensym behavior. To accomodate this, we change the
behavior of the old experimental option that `results` uses,
`genericsOpenSym`, so that ignores the information of whether or not
symbols are intentionally opened and always gives the opensym behavior
as long as it's enabled at instantiation time. This should keep
`results` working as is. However this differs from the normal opensym
switch in that it doesn't generate `nnkOpenSym`.
Before it was just a generics-only version of `openSym` along with
`templateOpenSym` which was only for templates. So `templateOpenSym` is
removed along with this change, but no one appears to have used it.

fixes #15314, fixes #24002
The OpenSym behavior first added to generics in #23091 now also applies
to templates, since templates can also capture symbols that are meant to
be replaced by local symbols if the context imports symbols with the
same name, as in the issue #24002. The experimental switch
`templateOpenSym` is added to enable this behavior for templates only,
and the experimental switch `openSym` is added to enable it for both
templates and generics, and the documentation now mainly mentions this
switch.
Additionally the logic for `nkOpenSymChoice` nodes that were previously
wrapped in `nkOpenSym` now apply to all `nkOpenSymChoice` nodes, and so
these nodes aren't wrapped in `nkOpenSym` anymore. This means
`nkOpenSym` can only have children of kind `nkSym` again, so it is more
in line with the structure of symchoice nodes. As for why they aren't
merged with `nkOpenSymChoice` nodes yet, we need some way to signal that
the node shouldn't become ambiguous if other options exist at
instantiation time, we already captured a symbol at the beginning and
another symbol can only replace it if it's closer in scope and
unambiguous.

refs https://github.com/nim-lang/Nim/pull/23873#discussion_r1687995060,
fixes #23386, fixes #23385, supersedes #23572
Turns the `nfOpenSym` node flag implemented in #23091 and extended in
#23102 and #23873, into a node kind `nkOpenSym` that forms a unary node
containing either `nkSym` or `nkOpenSymChoice`. Since this affects
macros working on generic proc AST, the node kind is now only generated
when the experimental switch `genericsOpenSym` is enabled, and a new
node flag `nfDisabledOpenSym` is set to the `nkSym` or `nkOpenSymChoice`
when the switch is not enabled so that we can give a warning.
Now that the experimental switch has more reasonable semantics, we
define `nimHasGenericsOpenSym2`.

I've been working on making some basic cuda examples work, both with
cuda (nvcc) and with AMD HIP (hipcc) https://github.com/monofuel/hippo
- hipcc is just a drop-in replacement for clang and works out of the box
with clang settings in Nim. hipcc is capable of compiling for AMD ROCm
or to CUDA, depending on how HIP_PLATFORM is set.
- nvcc is a little quirky. we can use `-x cu` to tell it to handle nim's
`.cpp` files as if they were `.cu` files. nvcc expects all backend
compiler flags to be wrapped with a special `-Xcompiler=""` flag when
compiling and also when linking.
I manually tested on a linux desktop with amd and a laptop with nvidia.

This adds nimsuggest support for displaying inlay hints for exceptions.
An inlay hint is displayed around function calls, that can raise an
exception, which isn't handled in the current subroutine (in other
words, exceptions that can propagate back to the caller). On mouse hover
on top of the hint, a list of exceptions that could propagate is shown.
The changes, required to support this are already commited to
nimlangserver and the VS code extension. The extension and the server
allow configuration for whether these new exception hints are enabled
(they can be enabled or disabled independently from the type hints), as
well as the inlay strings that are inserted before and after the name of
the function, around the function call. Potentially, one of these
strings can be empty, for example, the user can choose to add an inlay
hint only before the name of the function, or only after the name of the
function.

(#23102)
refs #23091, especially post merge comments
Unsure if `experimental` and `bind` are the perfect constructs to use
but they seem to get the job done here. Symbol nodes do not get marked
`nfOpenSym` if the `bind` statement is used for their symbol, and
`nfOpenSym` nodes do not get replaced by new local symbols if the
experimental switch is not enabled in the local context (meaning it also
works with `push experimental`). However this incurs a warning as the
fact that the node is marked `nfOpenSym` means we did not `bind` it, so
we might want to do that or turn on the experimental switch if we didn't
intend to bind it.
The experimental switch name is arbitrary and could be changed.

doesn't exist (#23017)
For example with the command `nim r foo/bar.nim`, if `foo/` doesn't
exist then it shows this message
```
oserrors.nim(92) raiseOSError
Error: unhandled exception: No such file or directory
Additional info: foo [OSError]
```
After PR it shows
```
Error: cannot open 'foo/bar.nim'
```
Which makes it line up with the error message if `foo/` did exist but
`bar.nim` didn't. Does this by using the same logic for [handling if the
file doesn't
exist](https://github.com/ire4ever1190/Nim/blob/0dc12ec24b7902ef0023a9e694faa11bcf99e257/compiler/options.nim#L785-L788)

When it is specified, the nimsuggest instance monitors whether this
process is still alive. In case it's found to be dead, nimsuggest shuts
itself down. Currently only implemented on POSIX and Windows platforms.
The switch is silently ignored on other platforms. Note that the Nim
language server should still try to shut down its child nimsuggest
processes. This switch just adds extra protection against crashing Nim
language server and gets rid of the remaining nimsuggest processes,
which consume memory and system resources.

This adds inlay hints support to nimsuggest. It adds a new command to
nimsuggest, called 'inlayHints'.
Currently, it provides type information to 'var' and 'let' variables. In
the future, inlay hints can also be added for 'const' and for function
parameters. The protocol also reserves space for a tooltip field, which
is not used, yet, but support for it can be added in the future, without
further changing the protocol.
The change includes refactoring to allow the 'inlayHints' command to
return a completely different structure, compared to the other
nimsuggest commands. This will allow other future commands to have
custom return types as well. All the previous commands return the same
structure as before, so perfect backwards compatibility is maintained.
To use this feature, an update to the nim language server, as well as
the VS code extension is needed.

* Implemented level based macro expand functionality
- it can handle single macro call or expand whole function/proc/etc and it
- In addition, I have altered the parser to provide the endInfo for the node.
The usefulness of the `endInfo` is not limited to the `expandMacro`
functionality but also it is useful for `ideOutline` functionality and I have
altered the ideOutline functionality to use `endInfo`. Note `endInfo` most of
the time is lost during the AST transformation thus in `nimsuggest.nim` I am
using freshly parsed tree to get the location information.
* Make sure we stop expanding correctly
* Test CI
* Fix tv3_outline.nim

* docgen: implement cross-document links
Fully implements https://github.com/nim-lang/RFCs/issues/125
Follow-up of: https://github.com/nim-lang/Nim/pull/18642 (for internal links)
and https://github.com/nim-lang/Nim/issues/20127.
Overview
--------
Explicit import-like directive is required, called `.. importdoc::`.
(the syntax is % RST, Markdown will use it for a while).
Then one can reference any symbols/headings/anchors, as if they
were in the local file (but they will be prefixed with a module name
or markup document in link text).
It's possible to reference anything from anywhere (any direction
in `.nim`/`.md`/`.rst` files).
See `doc/docgen.md` for full description.
Working is based on `.idx` files, hence one needs to generate
all `.idx` beforehand. A dedicated option `--index:only` is introduced
(and a separate stage for `--index:only` is added to `kochdocs.nim`).
Performance note
----------------
Full run for `./koch docs` now takes 185% of the time before this PR.
(After: 315 s, before: 170 s on my PC).
All the time seems to be spent on `--index:only` run, which takes
almost as much (85%) of normal doc run -- it seems that most time
is spent on file parsing, turning off HTML generation phase has not
helped much.
(One could avoid it by specifying list of files that can be referenced
and pre-processing only them. But it can become error-prone and I assume
that these linke will be **everywhere** in the repository anyway,
especially considering https://github.com/nim-lang/RFCs/issues/478.
So every `.nim`/`.md` file is processed for `.idx` first).
But that's all without significant part of repository converted to
cross-module auto links. To estimate impact I checked the time for
`doc`ing a few files (after all indexes have been generated), and
everywhere difference was **negligible**.
E.g. for `lib/std/private/osfiles.nim` that `importdoc`s large
`os.idx` and hence should have been a case with relatively large
performance impact, but:
* After: 0.59 s.
* Before: 0.59 s.
So Nim compiler works so slow that doc part basically does not matter :-)
Testing
-------
1) added `extlinks` test to `nimdoc/`
2) checked that `theindex.html` is still correct
2) fixed broken auto-links for modules that were derived from `os.nim`
by adding appropriate ``importdoc``
Implementation note
-------------------
Parsing and formating of `.idx` entries is moved into a dedicated
`rstidx.nim` module from `rstgen.nim`.
`.idx` file format changed:
* fields are not escaped in most cases because we need original
strings for referencing, not HTML ones
(the exception is linkTitle for titles and headings).
Escaping happens later -- on the stage of `rstgen` buildIndex, etc.
* all lines have fixed number of columns 6
* added discriminator tag as a first column,
it always allows distinguish Nim/markup entries, titles/headings, etc.
`rstgen` does not rely any more (in most cases) on ad-hoc logic
to determine what type each entry is.
* there is now always a title entry added at the first line.
* add a line number as 6th column
* linkTitle (4th) column has a different format: before it was like
`module: funcName()`, now it's `proc funcName()`.
(This format is also propagated to `theindex.html` and search results,
I kept it that way since I like it more though it's discussible.)
This column is what used for Nim symbols resolution.
* also changed details on column format for headings and titles:
"keyword" is original, "linkTitle" is HTML one
* fix paths on Windows + more clear code
* Update compiler/docgen.nim
