This is necessary since isGnuLibC() is true for hurd, so we need to be able to
represent a glibc version for it.
Also add an Os.TaggedVersionRange.gnuLibCVersion() convenience function.

The tool will now skip over undefined symbols. These can only occur as a result
of building musl without compiler-rt, i.e. -rtlib=none. Thanks to this, it's no
longer necessary to patch Zig's compiler-rt, nor is it necessary to maintain a
symbol blacklist.
See the updated instructions here: https://github.com/ziglang/zig/wiki/Updating-libc#updating-the-libcs-file
Additionally, the tool now produces slightly more compact output by recognizing
symbols that are defined for a single arch, for a family of arches, or only for
arches using 32-bit or 64-bit time as their primary ABI.
Finally, the tool now supports all architectures that we can emit code for, with
the single exception of x86_64-linux-muslx32. (x32 currently fails with a ton of
relocation errors, leading me to believe that it might be an LLVM or LLD bug.)
They way OpenSSH does key derivation to protect keys using a password
is not the standard PBKDF2, but something funky, picking key material
non-linearly.
* 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: 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.

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!

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.
Fixes#21002
