POSIX signal has an identical definition to ISO C signal:
https://pubs.opengroup.org/onlinepubs/9799919799/functions/signal.html
```c
void (*signal(int sig, void (*func)(int)))(int);
/* more readably restated by glibc as */
typedef void (*sighandler_t)(int);
sighandler_t signal(int signum, sighandler_t handler);
```
However, std/posix had omitted the function's return value; this fixes
that.
To prevent breaking every single line of code ever that touched this
binding (including mine...), I've also made it discardable.
Additionally, I have noticed that bsd_signal's type signature is wrong -
it should have been identical to signal. But bsd_signal was already
removed in POSIX 2008, and sigaction is the recommended, portable POSIX
signal interface. So I just deleted the bsd_signal binding.

(cherry picked from commit 483389d399)
Like quit, this function never returns.
Also, "code" was marked as "int", even though POSIX _exit takes a C int.
(cherry picked from commit f485973459)
This fixes several cases of the Nim binding of nfds_t being inconsistent
with the target platform signedness and/or size.
Additionally, it fixes poll's third argument (timeout) being set to Nim
"int" when it should have been "cint".
The former is the same issue that #23045 had attempted to fix, but
failed because it only considered Linux. (Also, it was only applied to
version 2.0, so the two branches now have incompatible versions of the
same bug.)
Notes:
* SVR4's original "unsigned long" definition is cloned by Linux and
Haiku. Nim got this right for Haiku and Linux-amd64, but it was wrong on
non-amd64 Linux.
* Zephyr does not have nfds_t, but simply uses (signed) "int". This was
already correctly reflected by Nim.
* OpenBSD poll.h uses "unsigned int", and other BSD derivatives follow
suit. This being the most commonly copied definition, the fallback case
now returns cuint. (This also seems to be correct for the OS X headers I
could find on the web.)
* This changes Nintendo Switch nfds_t to cuint from culong. It is
purportedly a FreeBSD derivative, so I *think* this is correct, but I
can't tell because I don't have access to the Nintendo Switch headers.
I have also moved the platform-specific Tnfds to posix.nim so that we
can reuse the fallback logic on all platforms. (e.g. specifying the size
in posix_linux_amd64 only to then use when defined(linux) in posix_other
seems redundant.)
(cherry picked from commit 67442471ae)
Previous example wouldn't run unless `std/posix` was imported and it
wasn't mentioned anywhere in the docs.
Other changes in the example:
- replaced magic number with constant `MaxWatches` .
- changed seq buffer to array, because length is already constant +
pointer is a bit nicer: `addr seq[0]` vs `addr arr`
- added example for getting a `cstring` name value from `InotifyEvent`
struct with explicit cast.
- added a bit more description to `inotify_init1` (copied from `man
inotify(7)`)

In this PR, the following changes were made:
1. Replaced `raise newException(OSError, osErrorMsg(errno))` in batches
with `raiseOSError(errcode)`.
2. Replaced `newException(OSError, osErrorMsg(errno))` in batches with
`newOSError(errcode)`.
There are still some places that have not been replaced. After checking,
they are not system errors in the traditional sense.
```nim
proc dlclose(lib: LibHandle) =
raise newException(OSError, "dlclose not implemented on Nintendo Switch!")
```
```nim
if not fileExists(result) and not dirExists(result):
# consider using: `raiseOSError(osLastError(), result)`
raise newException(OSError, "file '" & result & "' does not exist")
```
```nim
proc paramStr*(i: int): string =
raise newException(OSError, "paramStr is not implemented on Genode")
```
* Fix: make nintendoswitch someGcc, remove symlink support for nintendoswitch, add getAppFilename for nintendoswitch

ioselectors: ioselectors_epoll: for NuttX, limit initial numFD to configured value.
In the NuttX build config, there is a setting called "FS_NEPOLL_DESCRIPTORS".
--------
config FS_NEPOLL_DESCRIPTORS
int "Maximum number of default epoll descriptors for epoll_create1(2)"
default 8
---help---
The maximum number of default epoll descriptors for epoll_create1(2)
--------
For NuttX, change the number of fd arrays allocated by newSelector() to that value.

* Add general purpose `setFileSize` (unexported for now). Use to simplify
`memfiles.open` as well as make robust (via hard allocation, not merely
`ftruncate` address space allocation) on systems with `posix_fallocate`.
As part of this, fix a bad `closeHandle` return check bug on Windows and
add `MemFile.resize` for Windows now that setFileSize makes that easier.
* Adapt existing test to exercise newly portable `MemFile.resize`.
* Since Apple has never provided `posix_fallocate`, provide a fallback.
This is presently written in terms of `ftruncate`, but it can be
improved to use `F_PREALLOCATE` instead, as mentioned in a comment.

* fix posix.mq_receive compilation with cpp backend
* only enable runnableExample on posix
* linux, not posix
* simplify example
* add test
* mqueue.h does not exist on MacOS
* place test case in own block
* drop runnableExamples
* Implement Markdown indented code blocks
Additional indentation of 4 spaces makes a block an "indented code block"
(monospaced text without syntax highlighting).
Also `::` RST syntax for code blocks is disabled.
So instead of
```rst
see::
Some code
```
the code block should be written as
```markdown
see:
Some code
```
* Migrate RST literal blocks :: to Markdown's ones
* system refactor, move out 600 lines
* compilation, slice, backwardsindex, misc_num moved out of system
* some procs/types moved into arithmetics, basic_types
* system no longer depends on syncio
* some procs moved around to fit with their surroundings
* make exceptions an import, old ops to misc_num
* move instantiationInfo back
