Fix simple doc mistakes. (#17624)
* Add missing period in Stack's description

This looks fine in the source, but looks bad when seen on the documentation website.

* Correct documentation for attachSegfaultHandler()

The description for attachSegfaultHandler() looks pretty bad without indicating that the stuff at the end is code

* Added missing 'the's in Queue.put's documentation

* Fixed several errors in Stack's documentation

`push()` and `pop()` were not styled as code

There was no period after `pop()`, which looks bad on the documentation.

* Fix multiple problems in base64.zig

Both "invalid"s in Base64.decoder were not capitalized.

Missing period in documentation of Base64DecoderWithIgnore.calcSizeUpperBound.

* Fix capitalization typos in bit_set.zig

In DynamicBitSetUnmanaged.deinit's and DynamicBitSet.deinit's documentation, "deinitializes" was uncapitalized.

* Fix typos in fifo.zig's documentation

Added a previously missing period to the end of the first line of LinearFifo.writableSlice's documentation.
Added missing periods to both lines of LinearFifo.pump's documentation.

* Fix typos in fmt.bufPrint's documentation

The starts of both lines were not capitalized.

* Fix minor documentation problems in fs/file.zig

Missing periods in documentation for Permissions.setReadOnly, PermissionsWindows.setReadOnly, MetadataUnix.created, MetadataLinux.created, and MetadataWindows.created.

* Fix a glaring typo in enums.zig

* Correct errors in fs.zig

* Fixed documentation problems in hash_map.zig

The added empty line in verify_context's documentation is needed, otherwise autodoc for some reason assumes that the list hasn't been terminated and continues reading off the rest of the documentation as if it were part of the second list item.

* Added lines between consecutive URLs in http.zig

Makes the documentation conform closer to what was intended.

* Fix wrongfully ended sentence in Uri.zig

* Handle wrongly entered comma in valgrind.zig.

* Add missing periods in wasm.zig's documentation

* Fix odd spacing in event/loop.zig

* Add missing period in http/Headers.zig

* Added missing period in io/limited_reader.zig

This isn't in the documentation due to what I guess is a limitation of autodoc, but it's clearly supposed to be. If it was, it would look pretty bad.

* Correct documentation in math/big/int.zig

* Correct formatting in math/big/rational.zig

* Create an actual link to ZIGNOR's paper.

* Fixed grammatical issues in sort/block.zig

This will not show up in the documentation currently.

* Fix typo in hash_map.zig

std.math: add nextAfter (#16894)
`nextAfter()` returns the next representable value after `x` in the direction of `y` and is a standard math library function ([C++](https://en.cppreference.com/w/cpp/numeric/math/nextafter), [Java](https://docs.oracle.com/javase/8/docs/api/java/lang/Math.html#nextAfter-double-double-)). It is primarily useful for bitwise incrementing/decrementing floats.

This implementation supports runtime integers, runtime floats and `comptime_int`. `comptime_float` is not supported because NaNs/infinities are intentionally difficult to obtain and because I'm not sure if the fact that it's backed by `f128` is supposed to be an implementation detail. Either way, the user could just call the function with the floating-point type whose behavior they want at comptime and then cast the result to `comptime_float`.

The float implementation was ported from mingw-w64 with some slight changes made possible because the Zig standard library doesn't care about raising FP exceptions.

The number of test cases may seem excessive but they should cover every normal and edge case for every float type and are especially important for verifying that `f80` works.

283afb50b5 AstGen: disallow '-0' integer literal
The intent here is ambiguous: this resolves to the comptime_int '0', but
it's likely the user meant to use a floating-point literal.

Make NaNs quiet by default and other NaN tidy-up (#16826)

2b8687ba2d std.math.big.int: better name for equal function
All of the std except these few functions call it "eql" instead of "eq".
This has previously tripped me up when I expected the equality check function to be called "eql"
(just like all the rest of the std) instead of "eq".

The motivation is consistency.

If search "eq" on Autodoc, these functions stick out and it looks inconsistent.

I just noticed there are also a few functions spelling it out as "equal" (such as std.mem.allEqual).
Maybe those functions should also spell it "eql" but that can be done in a future PR.

f26dda2117 all: migrate code to new cast builtin syntax
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:

* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
