linux-user: Trace rt_sigprocmask's sigsets

Add a function for formatting target sigsets. It can be useful for
other syscalls in the future, so put it into the beginning of strace.c.
For simplicity, do not implement the strace's ~[] output syntax.

Add a rt_sigprocmask return handler.

Example outputs:

753914 rt_sigprocmask(SIG_BLOCK,[SIGCHLD SIGTSTP SIGTTIN SIGTTOU],0x00007f80fddfe380,8) = 0 (oldset=[SIGTTOU])
753914 rt_sigprocmask(SIG_SETMASK,[SIGCHLD],NULL,8) = 0
753914 rt_sigprocmask(SIG_BLOCK,NULL,0x00007f80fddff3c0,8) = 0 (oldset=[])

linux-user: add strace support for openat2

This commit adds support for the `openat2()` to `QEMU_STRACE`. It
will use the `openat2.h` header if available to create user
readable flags for the `resolve` argument but does not require
the header otherwise.

It also makes `copy_struct_from_user()` available via `qemu.h`
and `open_how_ver0` via `syscall_defs.h` so that strace.c can use
them.

linux-user: Fix fcntl64() and accept4() for 32-bit targets

A set of 3 patches:
The first two patches fix fcntl64() and accept4().
the 3rd patch enhances the strace output for pread64/pwrite64().

This pull request does not includes Richard's mmap2 patch:
https://patchew.org/QEMU/20230630132159.376995-1-richard.henderson@linaro.org/20230630132159.376995-12-richard.henderson@linaro.org/

Changes:
v3:
- added r-b from Richard to patches #1 and #2
v2:
- rephrased commmit logs
- return O_LARGFILE for fcntl() syscall too
- dropped #ifdefs in accept4() patch
- Dropped my mmap2() patch (former patch #3)
- added r-b from Richard to 3rd patch

linux-user: Add translation for argument of msync()

msync() uses the flags MS_ASYNC, MS_INVALIDATE and MS_SYNC, which differ
between platforms, specifcally on alpha and hppa.

Add a target to host translation for those and wire up a nicer strace
output.

This fixes the testsuite of the macaulay2 debian package with a hppa-linux
guest on a x86-64 host.

linux-user: Implement faccessat2

User space has been preferring this syscall for a while, due to its
closer match with C semantics, and newer platforms such as LoongArch
apparently have libc implementations that don't fallback to faccessat
so normal access checks are failing without the emulation in place.

Tested by successfully emerging several packages within a Gentoo loong
stage3 chroot, emulated on amd64 with help of static qemu-loongarch64.
