Haiku support for Nim (#8542)
* posix_other: Haiku now has spawn.h This is added per https://dev.haiku-os.org/ticket/13446 * posix_other: Add Haiku specific Dirent members * cpuinfo: Add an implementation for Haiku * distros: Add basic Haiku support * encodings: update Haiku support * fenv, math: Haiku now provides libm * times: Add Haiku struct members * ansi_c, osalloc: Add Haiku constants * threads: Add Haiku support * testament: Haiku uses LIBRARY_PATH * nim.cfg: Update Haiku support libnetwork should only be linked if network functions are used * threads: Haiku does not support -pthread switch * tworkingdir: Haiku's env is in /bin * posix_other: add SIGKILLTHR for Haiku * sockets: link with libnetwork on Haiku * coro: correct ucontext.h location http://pubs.opengroup.org/onlinepubs/009696699/basedefs/ucontext.h.html * coro: ucontext backend is not available on Haiku Haiku doesn't provide the <ucontext.h> header, as it was removed from POSIX * coro: fix setjmp backend The compiler does not allow statements after a noreturn function * nativesockets: Haiku doesn't support AI_V4MAPPED * system: hostOS can contains "haiku" * os: add support for Haiku's packagefs packagefs is read-only, but there are writable holes to the underlying file system as well * os: update constant for Haiku
