* Error -> Defect for defects
The distinction between Error and Defect is subjective,
context-dependent and somewhat arbitrary, so when looking at an
exception, it's hard to guess what it is - this happens often when
looking at a `raises` list _without_ opening the corresponding
definition and digging through layers of inheritance.
With the help of a little consistency in naming, it's at least possible
to start disentangling the two error types and the standard lib can set
a good example here.

When I heard that this feature existed, and found the 2018 changelog entry that said `not nil` was made experimental (https://github.com/nim-lang/Nim/blob/devel/changelogs/changelog_0_19_0.md#changes-affecting-backwards-compatibility), I looked for `not nil` documentation in https://nim-lang.org/docs/manual_experimental.html. When I didn’t find it there, I initially assumed the feature had no documentation. This change moves the documentation to where readers will expect it.
As well as moving the text to another file, I added instructions for enabling the experimental feature and tweaked some wording.

and improve wording in other ways
Showing that `nil` can be assigned helps to warn readers that variables can be `nil` even after being assigned a value.

* allow defects to be caught even for --exceptions:goto (WIP)
* implemented the new --panics:on|off switch; refs https://github.com/nim-lang/RFCs/issues/180
* new implementation for integer overflow checking
* produce a warning if a user-defined exception type inherits from Exception directly
* applied Timothee's suggestions; improved the documentation and replace the term 'checked runtime check' by 'panic'
* fixes #13627
* don't inherit from Exception directly

* first implementation of the =trace and =dispose hooks for the cycle collector
* a cycle collector for ARC: progress
* manual: the .acyclic pragma is a thing once again
* gcbench: adaptations for --gc:arc
* enable valgrind tests for the strutils tests
* testament: better valgrind support
* ARC refactoring: growable jumpstacks
* ARC cycle detector: non-recursive algorithm
* moved and renamed core/ files back to system/
* refactoring: --gc:arc vs --gc:orc since 'orc' is even more experimental and we want to ship --gc:arc soonish

Said that you can have custom exceptions and showed how to create and raise them.

* Clarifies experimental / parallel on manual.rst
Details:
Calling `useParallel()` in example fails with compiler error
Error: 'parallel' section without 'spawn'
Adding `spawn` causes error:
Error: internal error: (filename: "ccgexprs.nim", line: 1032, column: 17)
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c <file>
Therefore a separate proc, `threadedEcho`, is added for the echo'ing
of the string, which allows the example to build, however, `sync()`
must be added so that the "echo in parallel" strings will actually
be shown on the terminal. Otherwise, the program will spawn of the
threads and exit before they can return to the main thread.
* Fixes and clarifies example for threading in manual.rst
Issue:
Calling useParallel() in example failed with compiler error
`Error: 'parallel' section without 'spawn'`
Adding spawn yielded compiler error:
```bash
Error: internal error: (filename: "ccgexprs.nim", line: 1032, column: 17)
No stack traceback available
To create a stacktrace, rerun compilation with ./koch temp c
```
Proposed Solution:
- Separate proc, threadedEcho, is added for the echo'ing
of the string, which allows the example to build
- Added the thread number so that it can demonstrate that sometimes
threads which were started sooner, come back after threads which
were started later.

* Fix many broken links
Note that contrary to what docgen.rst currently says, the ids have
to match exactly or else most web browsers will not jump to the
intended symbol.
* Prefer relative links for Nim documentation
This is more friendly to those browsing the documentation without
a network connection. The nim-doc package in Debian allows this,
for example.
Also, the domain name being used was not consistent. It could have
been either nim-lang.org or nim-lang.github.io, and those reading
the stable docs could have found themselves suddenly reading the
devel docs instead.
* koch.rst: remove link to nonexistent section
* manual.rst: remove unintended link
cast[T](0) is interpreted as a link to id 0 with text T, so escape
the opening parentheses to display the intended output.
* asyncstreams: replace unintended link with emphasis
* Fix word wrapping
