eb37552536 Remove numerous things deprecated during the 0.14 release cycle
Basically everything that has a direct replacement or no uses left.

Notable omissions:

- std.ArrayHashMap: Too much fallout, needs a separate cleanup.
- std.debug.runtime_safety: Too much fallout.
- std.heap.GeneralPurposeAllocator: Lots of references to it remain, not
  a simple find and replace as "debug allocator" is not equivalent to
  "general purpose allocator".
- std.io.Reader: Is being reworked at the moment.
- std.unicode.utf8Decode(): No replacement, needs a new API first.
- Manifest backwards compat options: Removal would break test data used
  by TestFetchBuilder.
- panic handler needs to be a namespace: Many tests still rely on it
  being a function, needs a separate cleanup.

7e2a26c0c4 std.io.Writer.printValue: rework logic
Alignment and fill options only apply to numbers.

Rework the implementation to mainly branch on the format string rather
than the type information. This is more straightforward to maintain and
more straightforward for comptime evaluation.

Enums support being printed as decimal, hexadecimal, octal, and binary.

`formatInteger` is another possible format method that is
unconditionally called when the value type is struct and one of the
integer-printing format specifiers are used.

5378fdb153 std.fmt: fully remove format string from format methods
Introduces `std.fmt.alt` which is a helper for calling alternate format
methods besides one named "format".

0e37ff0d59 std.fmt: breaking API changes
added adapter to AnyWriter and GenericWriter to help bridge the gap
between old and new API

make std.testing.expectFmt work at compile-time

std.fmt no longer has a dependency on std.unicode. Formatted printing
was never properly unicode-aware. Now it no longer pretends to be.

Breakage/deprecations:
* std.fs.File.reader -> std.fs.File.deprecatedReader
* std.fs.File.writer -> std.fs.File.deprecatedWriter
* std.io.GenericReader -> std.io.Reader
* std.io.GenericWriter -> std.io.Writer
* std.io.AnyReader -> std.io.Reader
* std.io.AnyWriter -> std.io.Writer
* std.fmt.format -> std.fmt.deprecatedFormat
* std.fmt.fmtSliceEscapeLower -> std.ascii.hexEscape
* std.fmt.fmtSliceEscapeUpper -> std.ascii.hexEscape
* std.fmt.fmtSliceHexLower -> {x}
* std.fmt.fmtSliceHexUpper -> {X}
* std.fmt.fmtIntSizeDec -> {B}
* std.fmt.fmtIntSizeBin -> {Bi}
* std.fmt.fmtDuration -> {D}
* std.fmt.fmtDurationSigned -> {D}
* {} -> {f} when there is a format method
* format method signature
  - anytype -> *std.io.Writer
  - inferred error set -> error{WriteFailed}
  - options -> (deleted)
* std.fmt.Formatted
  - now takes context type explicitly
  - no fmt string

6b41beb370 big.int: implement float conversions
These conversion routines accept a `round` argument to control how the
result is rounded and return whether the result is exact. Most callers
wanted this functionality and had hacks around it being missing.

Also delete `std.math.big.rational` because it was only being used for
float conversion, and using rationals for that is a lot more complex
than necessary. It also required an allocator, whereas the new integer
routines only need to be passed enough memory to store the result.

ed284c1f98 big.int: fix yet another truncate bug
Too many bugs have been found with `truncate` at this point, so it was
rewritten from scratch.

Based on the doc comment, the utility of `convertToTwosComplement` over
`r.truncate(a, .unsigned, bit_count)` is unclear and it has a subtle
behavior difference that is almost certainly a bug, so it was deleted.

compiler,std: implement ZON support
This commit allows using ZON (Zig Object Notation) in a few ways.

* `@import` can be used to load ZON at comptime and convert it to a
  normal Zig value. In this case, `@import` must have a result type.
* `std.zon.parse` can be used to parse ZON at runtime, akin to the
  parsing logic in `std.json`.
* `std.zon.stringify` can be used to convert arbitrary data structures
  to ZON at runtime, again akin to `std.json`.

3543f28320 std.math.big.int: fix shiftRight sign handling
Closes #21311

The sign of the result `r` needs to be initialized before the correction
`r.addScalar(r.toConst(), -1)`, or the intended end result could be off
by 2 (depending on the original sign of `r`).

std: update std.builtin.Type fields to follow naming conventions
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.

This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938.

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

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
