This CL updates the windows.UTF16FromString and windows.UTF16ToString
implementation so they forward to their syscall counterparts.

The standard library uses these particular syscall functions across
the board as it can't depend on x/sys. This means that even if the
syscall API is frozen, the implementation still receives improvements
and bug fixes, such as CL 425054.

Porting CL 425054 to x/sys is possible, but for this particular case
I think it's better to just call the syscall package. This way both
repos will benefit from future improvements (which I plan to do soon).

A uint64 >> 64 is reported as a mistake by the vet shift check.
This is arguably a bug in vet, but we can't fix the old releases,
so work around it.

This provides a ClockAdjtime function providing access to the clock_adjtime system call on Linux.
The clock_adjtime system call is like adjtimex, but takes a clockid_t as its first argument.
The unix package already provides Adjtimex and the associated Timex struct; it also provides
the other functions that take a clockid_t (like ClockGettime). ClockAdjtime is an essential
system call for programs that want to use the Linux PTP hardware clock infrastructure (see
https://docs.kernel.org/driver-api/ptp.html).

This change adds "." and "-" support for DLL filenames in "//sys".

Supporting "." requires a change in how mkwinsyscall handles the
"= <filename>.<function>" syntax. Instead of assuming that only one "."
can appear in this string, now mkwinsyscall assumes that any additional
"." belongs to the filename.

Supporting "." also requires changing how Go identifiers are created for
each DLL. This change also allows mkwinsyscall to support "-". When
creating a Go identifier, "." and "-" in the DLL filename are replaced
with "_". Otherwise, mkwinsyscall would produce invalid Go code, causing
"format.Source" to fail.

Includes a test for the new behavior. There aren't yet any cases where
this code is executed while generating the x/sys/windows syscalls. The
syscalls "SetSocketMediaStreamingMode" from "windows.networking.dll" and
"WslRegisterDistribution" from "api-ms-win-wsl-api-l1-1-0.dll" can be
successfully called using this change, but these syscalls have no known
use in Go so they are not included in this change.

This change writes the unformatted Go source code to a temp file if

it can be difficult to diagnose them without this context.

Support for LoongArch has been merged upstream. This allows to
drop the loong64 specific glibc patches.

Because the header file sys/mount.h of glibc 2.36 includes fcntl.h
(commit 78a408ee7ba041fc8d5dbd5f67065b4a982c11e5), this will leads to
duplicate definition of structure stat on MIPS64.  In order to solve
this error, use the custom type my_stat to generate the Go Stat_t.

The purpose of the _zero variable is to provide a valid address for a
pointer to an array of length zero. All other uses of the variable
take its address, but one reference to it (added in CL 147850043)
converts the variable (which has type uintptr) directly to an
unsafe.Pointer, producing a nil pointer instead of a non-nil pointer
to a zero-length array.

This typo is caught by 'go vet', but was masked for a long time by the
numerous false-positive warnings for the same check (#41205).

For golang/go#41205.

Despite having the misleading type "void*" in the C API, the "offs"
field of the ptrace_io_desc struct is an offset within the child
process, and thus is not necessarily a valid pointer at all in the
parent process. The Go unsafe.Pointer type must refer only to valid
pointers, so converting this field through unsafe.Pointer is incorrect
and (in some cases) dangerous.

While we're here, let's also rename the "addr" function argument to
"offs", since that's the corresponding ptrace_io_desc field. It's very
confusing to have a function argument named "attr" that doesn't map to
the struct field of the same name!

For golang/go#58351.
