While fixing several bugs in path handling on Windows,

After, it considered only the \\? prefix to be the volume name.

[release-branch.go1.21] crypto/rand,runtime: switch RtlGenRandom for …
9e43850 
…ProcessPrng

RtlGenRandom is a semi-undocumented API, also known as
SystemFunction036, which we use to generate random data on Windows.
It's definition, in cryptbase.dll, is an opaque wrapper for the
documented API ProcessPrng. Instead of using RtlGenRandom, switch to
using ProcessPrng, since the former is simply a wrapper for the latter,
there should be no practical change on the user side, other than a minor
change in the DLLs we load.

[release-branch.go1.21] runtime: call enableMetadataHugePages and its…
3684d19 
… callees on the systemstack

These functions acquire the heap lock. If they're not called on the
systemstack, a stack growth could cause a self-deadlock since stack
growth may allocate memory from the page heap.

This has been a problem for a while. If this is what's plaguing the
ppc64 port right now, it's very surprising (and probably just
coincidental) that it's showing up now.

For golang#64050.

[release-branch.go1.21] cmd/compile: fix findIndVar so it does not ma…
f7a79cb 
…tch disjointed loop headers

Fix golang#63984

parseIndVar, prove and maybe more are on the assumption that the loop header
is a single block. This can be wrong, ensure we don't match theses cases we
don't know how to handle.

In the future we could update them so that they know how to handle such cases
but theses cases seems rare so I don't think the value would be really high.
We could also run a loop canonicalization pass first which could handle this.

The repro case looks weird because I massaged it so it would crash with the
previous compiler.

[release-branch.go1.21] net/http: limit chunked data overhead
ec8c526 
The chunked transfer encoding adds some overhead to
the content transferred. When writing one byte per
chunk, for example, there are five bytes of overhead
per byte of data transferred: "1\r\nX\r\n" to send "X".

Chunks may include "chunk extensions",
which we skip over and do not use.
For example: "1;chunk extension here\r\nX\r\n".

A malicious sender can use chunk extensions to add
about 4k of overhead per byte of data.
(The maximum chunk header line size we will accept.)

Track the amount of overhead read in chunked data,
and produce an error if it seems excessive.
