readAtLeast is greedy and will read the entire length of the buffer if it can. However, reading past the end of the cert in this case is useless, so reading the full length of the buffer just puts an increasingly large (due to the growth algorithm of ArrayList) collection of wasted bytes after each cert in cb.bytes.
In practical terms, this ends up saving potentially millions of bytes of wasted reads/allocations. In my testing, after reading the keychain files on my machine, cb.bytes ends up with these capacities:
- Before: cb.bytes.capacity = 32720747
- After: cb.bytes.capacity = 251937
That's a decrease of 99.2%
Additionally, swaps to readNoEof since it should be an error to hit EOF without reading the full cert size.

In the original PR that implemented this (https://github.com/ziglang/zig/pull/14325), it included a list of references for the keychain format. Multiple of those references include the checks that are added in this commit, and empirically this fixes the loading of a real keychain file that was previously failing (it had both a record with offset 0 and a record with cert_size 0).
Fixes #22870

It is now composed of these main sections:
* Declarations that are shared among all operating systems.
* Declarations that have the same name, but different type signatures
depending on the operating system. Often multiple operating systems
share the same type signatures however.
* Declarations that are specific to a single operating system.
- These are imported one per line so you can see where they come from,
protected by a comptime block to prevent accessing the wrong one.
Closes #19352 by changing the convention to making types `void` and
functions `{}`, so that it becomes possible to update `@hasDecl` sites
to use `@TypeOf(f) != void` or `T != void`. Happily, this ended up
removing some duplicate logic and update some bitrotted feature
detection checks.
A handful of types have been modified to gain namespacing and type
safety. This is a breaking change.
Oh, and the last usage of `usingnamespace` site is eliminated.

closes #5019

This fixes issues targetting both `x86_64-linux` and `x86_64-macos` with
the self-hosted backend.

Let's take this breaking change opportunity to fix the style of this
enum.

Use inline to vastly simplify the exposed API. This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.

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
