windows: add RtlCaptureContext, RtlLookupFunctionEntry, RtlVirtualUnwind and supporting types
windows: fix alignment of CONTEXT structs to match winnt.h as required by RtlCaptureContext (fxsave instr)

- Add an assert that an exclusive lock is help to writeManifest
- Only call writeManifest in updateCObject if an exclusive lock is held
- cache: fixup test to verify hits don't take an exclusive lock, instead of writing the manifest
Before, --color on would affect colored compile error printing but not
affect terminal progress bar printing. It was intended for this option
to affect both; now it does.
This causes a failure when building the language reference, which
contains code for parsing terminal output and rendering HTML. Now it
must be expanded to handle 'K' and 'D' codes to simulate a terminal
cursor moving, and the CI will fail until that capability is added in a
later commit of this branch.
I extracted this change from #13560 so that the idea is not lost but we
can solve this issue separately.
This is simply a small convenience wrapper around
'meta.fieldInfo(T, .field).type'. However, this operation is common
enough that it makes sense to have its own function for.
When outputting the names section, we should output the actual symbol
name rather than the import name. This makes sure that symbols with
an explicit name set have the correct name but retain the import name
too.
We also now correctly mangle the name of an extern function with an
explicit library name. This ensures that functions that have a
different library name, but the same import/function name, can be
resolved correctly with other modules and don't resolve to the
same symbol.
Although RFC 8446 states:
> Each party MUST send a "close_notify" alert before closing its write
> side of the connection
In practice many servers do not do this. Also in practice, truncation
attacks are thwarted at the application layer by comparing the amount of
bytes received with the amount expected via the HTTP headers.
This allows for a more optimal std.crypto.tlcsprng codepath.
Without it a an "incorrect alignment" panic is triggered from
crypto.tlcsprng which aligns a threadlocal but it's actually
not aligned, thus detected by the safety check.
It appears that LLVM-IR does attribute the storage with alignment
but it is ultimately not respected in the final binary for netbsd
and dragonfly.
- per darwin-xnu source, fcntl F_GETPATH will return ENOSPC when path
exceeds either user-supplied buffer or system MAXPATHLEN
- macOS does not document this (and other) possible errno values
- first convert to lower-case then perform mappings
- effect: freebsd, netbsd and openbsd convert arch `amd64` to `x86_64`
- effect: convert `arm64` to `aarch64`
