36c869dc14 std: Make windows.ReadFile allow short reads 
Make it behave like the read() wrapper for unix systems.
Reading the whole buffer breaks some use-cases like buffered readers
over sockets.

Closes #7121

bf03ae7acc std.fs.path.dirname: return null when input path is root 
This intentionally diverges from the unix dirname command, as well as
Python and Node.js standard libraries, which all have this edge case
return the input path, unmodified. This is a footgun, and nobody should
have ever done it this way.

Even the man page contradicts the behavior. It says:
"strip last component from file name". Now consider, if you
remove the last item from an array of length 1, then you
have now an array of length 0. After you strip the last component, there
should be no components remaining. Clearly, returning the input parameter
unmodified in this case does not match the documented behavior. This is
my justification for taking a stand on this API design.

678bd4fc89 "ResetEvent" test seems to have a too short timeout: the test is failing randomly on OpenBSD 
raise the timeout to 100ms to be sure that if it fails (timeout is returned) it is due to a real problem.
the test shouldn't be longer: it will wait more time only on failure.

427a212e38 Don't prevent compilation on platforms where debug info is unsupported 
We don't support debug information on platforms that are not tier-1,
but it shouldn't be a hard error that completely prevents compilation.

bd07154242 Add mem.timingSafeEql() for constant-time array comparison 
This is a trivial implementation that just does a or[xor] loop.

However, this pattern is used by virtually all crypto libraries and
in practice, even without assembly barriers, LLVM never turns it into
code with conditional jumps, even if one of the parameters is constant.

This has been verified to still be the case with LLVM 11.0.0.

e7b60b219b std/crypto: don't constrain Gimli hash output to a fixed length 
As documented in the comment right above the finalization function,
Gimli can be used as a XOF, i.e. the output doesn't have a fixed
length.

So, allow it to be used that way, just like BLAKE3.

73aef46f7d std.crypto: namespace constructions a bit more 
With the simple rule that whenever we have or will have 2 similar
functions, they should be in their own namespace.

Some of these new namespaces currently contain a single function.

This is to prepare for reduced-round versions that are likely to
be added later.
