e2f24a2d70 Allocator.free: document zero-length behavior
It wasn't immediately clear from the implementation whether passing
zero-length memory to free() was undefined behavior or intentionally
supported. Since ArrayList and other core data structures rely on
this behavior working correctly, this should be explicitly documented
as part of the public API contract.

c894ac09a3 dwarf: fix stepping through an inline loop containing one statement
Previously, stepping from the single statement within the loop would
always exit the loop because all of the code unrolled from the loop is
associated with the same line and treated by the debugger as one line.

std.crypto.aes: introduce AES block vectors (#22023)
* std.crypto.aes: introduce AES block vectors

Modern Intel CPUs with the VAES extension can handle more than a
single AES block per instruction.

So can some ARM and RISC-V CPUs. Software implementations with
bitslicing can also greatly benefit from this.

Implement low-level operations on AES block vectors, and the
parallel AEGIS variants on top of them.

AMD Zen4:

      aegis-128x4:      73225 MiB/s
      aegis-128x2:      51571 MiB/s
       aegis-128l:      25806 MiB/s
      aegis-256x4:      46742 MiB/s
      aegis-256x2:      30227 MiB/s
        aegis-256:       8436 MiB/s
       aes128-gcm:       5926 MiB/s
       aes256-gcm:       5085 MiB/s

AES-GCM, and anything based on AES-CTR are also going to benefit
from this later.

* Make AEGIS-MAC twice a fast

crypto.keccak.State: add checks to prevent insecure transitions (#22020)
* crypto.keccak.State: don't unconditionally permute after a squeeze()

Now, squeeze() behaves like absorb()

Namely,

squeeze(x[0..t]);
squeeze(x[t..n)); with t <= n

becomes equivalent to squeeze(x[0..n]).

* keccak: in debug mode, track transitions to prevent insecure ones.

Fixes #22019

865ef24518 build: don't hang when capturing Stdout of verbose Build.Step.Run
When using Build.Step.Run.captureStdOut with a program that prints more
than 10 megabytes of output, the build process hangs.

This is because evalGeneric returns an error without reading child's
stdin till the end, so we subsequently get stuck in `try child.wait()`.

To fix this, make sure to kill the child in case of an error!

std.crypto: make the key pair API creation consistent (#21955)
Our key pair creation API was ugly and inconsistent between ecdsa
keys and other keys.

The same `generate()` function can now be used to generate key pairs,
and that function cannot fail.

For deterministic keys, a `generateDeterministic()` function is
available for all key types.

Fix comments and compilation of the benchmark by the way.

9ebce51e16 compiler: un-jit zig fmt
This command being JITed leads to a substantially worse first-time user
experience, since you have to wait for upwards of 20 seconds for
`fmt.zig` to build. This is especially bad when your editor is
configured to run `zig fmt` on save and does so in a blocking manner. As
such, it makes sense from a usability perspective to not JIT this
particular command.

9373abf7f7 std.http.Client: change ssl key log creation permission bits
This is the same mode used by openssh for private keys.  This does not
change the mode of an existing file, so users who need something
different can pre-create the file with their designed permissions or
change them after the fact, and running another process that writes to
the key log will not change it back.
