Simon and I have worked on these on and off for a number of projects
over the last 3 years and by now it's quite stable and mature. Rather
than carrying this around privately, these have now been updated to be
in the style of x/sys/windows, in this case matching how the
security_windows.go file does things. Specifically, because these APIs
are kind of hard to work with, and quite lengthy, we split them off into
a setupapi_windows.go file, just like security_windows.go. We already
had the setupapierrors_windows.go file, so that's been folded into the
new one that contains the additional definitions nad functions.
These APIs are among the most obtuse to work with in all of Win32, so
considerable attention has been spent trying to make these wrappers both
quite "raw" so that they match the win32, but also accessible from Go.
The fact that they're so old in Windows history makes for a few tricky
things, like struct padding that doesn't quite match Go's rules, but
we've been able to accommodate basically everything after quite a bit of
work.

Currently if TestPoll fails because an unexpected event fired, we just
print that it happened, not which one fired. #49380 has been difficult
to reproduce, so printing more information for this case would be
helpful.
Updates #49380.

Factor mkmerge.go and mkmerge_test.go into package internal/mkmerge.
Due to ignore constraints, mkmerge_test.go wasn't run by the Go
builders and failing tests were unnoticed.
Factoring mkmerge into its own package and removing ignore constraints
makes the tests run automatically by the Go builders.

Mount the data volume for the Docker-based builder at x/sys instead of
x/sys/unix.
The x/sys/go.mod file was not included in the data volume when mounting
x/sys/unix. This breaks module-aware go commands that run within the
Docker container.
Fix this problem by mounting the volume at x/sys and updating the
working directory of the builder accordingly.

CL 361154 updated the standard syscall package to document that
successive calls to syscall.RegEnumKeyEx must occur on the same OS

golang/go#49320).
This use in x/sys needs to be updated to comply with the
newly-discovered requirement.

Darwin doesn't save/restore the AVX-512 mask registers when
processing a signal. Go generates lots of signals, which cause
the mask registers to randomly get clobbered. Better to pretend
that AVX-512 isn't supported.

id using the kern.proc.uid sysctl and is still backwards compatible to
original implementation, i.e. still allows the kern.proc.all sysctl

over Windows events, which resulted in non-obvious control flow.
NewCallback makes it possible to rewrite all of this in vanilla Go. This
also enables the service test on the Go builders, as modifying system
services shouldn't be an issue there.
