`len` could contain side effects and may result in different values when
substituted twice in the template expansion. Instead, capture the result
of substituting `len` once.

* Remove Defect from raises list
Since defects aren't tracked anymore this causes a hint to pop up mentioning it
* Still track Defect when getting ran with an older Nim version
The raises followed a pattern so moving them into a pragma didn't seem to cause any extra problems
a warning message been added to the documentation to remind users that the timeout parameter is expressed in milliseconds, not seconds. to help prevent confusion and unexpected behaviours.
* Fix: make nintendoswitch someGcc, remove symlink support for nintendoswitch, add getAppFilename for nintendoswitch
* Fix: use getApplHeuristic on nintendoswitch

* 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.
* This adds `parseutils.parseSize`, an inverse to `strutils.formatSize`
which has existed since 2017.
It is useful for parsing the compiler's own output logs (like SuccessX)
or many other scenarios where "human readable" units have been chosen.
The doc comment and tests explain accepted syntax in detail.
Big units lead to small numbers, often with a fractional part, but we
parse into an `int64` since that is what `formatSize` stringifies and
this is an inverse over partial function slots. Although metric
prefixes z & y for zettabyte & yottabyte are accepted, these will
saturate the result at `int64.high` unless the qualified number is a
small fraction. This should not be much of a problem until such sizes
are common (at which point another overload with the parse result
either `float64` or `int128` could be added).
Tests avoids `test()` because of a weakly related static: test() failure
as mentioned in https://github.com/nim-lang/Nim/pull/21325. This is a
more elemental VM failure. As such, it needs its own failure exhibition
issue that is a smaller test case. (I am working on that, but unless
there is a burning need to `parseSize` at compile-time before run-time
it need not hold up this PR.)
* This worked with `int` but fails with `int64`. Try for green tests.
* Lift 2-result matching into a `checkParseSize` template and format as a
table of input & 2 expected outputs which seems nicer and to address
https://github.com/nim-lang/Nim/pull/21349#pullrequestreview-1294407679
* Fix (probably) the i386 trouble by using `int64` consistently.
* Improve documentation by mentioning saturation.
* Improve documentation with `runnableExamples` and a little more detail in
the main doc comment based on excellent code review by @juancarlospaco:
https://github.com/nim-lang/Nim/pull/21349#pullrequestreview-1294564155
* Address some more @juancarlospaco code review concerns.
* Remove a stray space.
* Mention milli-bytes in docs to maybe help clarify why wild conventions
are so prone to going case-insensitive-metric.
* Add some parens.
* Add test cases
* Implement contains for CacheSeq
* Implement contains for CacheTable
* Fix implementation of hasKey
* Remove contains for CacheSeq
Fix runnable examples
I was accidently using --doccmd:skip so I didn't spot the failure locally

* Add docs informing about gotcha of clients
It is a hidden problem that AsyncHttpClient-instances *can not* deal with multiple requests at once.
Similar to normal HttpClients they can only deal with sending one request at a time.
This is not told anywhere in the documentation, but critical information that should be available to the user.

parseopt.nim documentation clarity
Added example for default values to cmd line parameters.
Additionally, added lines in getopt documentation about case switching still requiring the `cmdEnd` kind. Hopefully this clears up any vagueness for those following along in the example but omitting the `cmdEnd` in the case because the documentation said it wasn't needed.
* 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

* avoiding allocating an unnecessary byte for IPv4
The inet.h file uses 16 as the string in C needs the last null byte
1b929c02af/include/linux/inet.h (L49)
However, strings in Nim do not need this. So one byte is being allocated unnecessary and will never be used.
* avoid unnecessary allocation in IPv6 dollar
It is currently allocating 48 bytes. However, the Nim implementation for IPv6 will print a maximum of 39 characters. Nim does not implement IPv6 "0000:0000:0000:0000:0000:ffff:255.255.255.255" (45 characters) nor "0000:0000:0000:0000:0000:ffff:255.255.255.255%3" (47 characters).
The indication in inet.h for 48 is due to the maximum use of 47 characters of a C string that needs a null byte at the end. So 48.
