  linux-user/signal.c: Fix AArch64 big-endian FP register restore

Fix the loop restoring the FP registers from the signal frame to match
the one used when setting up the signal frame, so that it handles
TARGET_WORDS_BIGENDIAN being set.

  linux-user: Don't use UID16 on AArch64

The AArch64 kernel defines its __kernel_uid_t type as 32 bits, unlike
32 bit ARM, so don't enable our 16-bit UID wrapper handling.

  linux-user: Fix getresuid, getresgid if !USE_UID16

The size of the UID/GID types depends on whether USE_UID16 is
defined. Define a new put_user_id() which writes a uid/gid
type to guest memory. This fixes getresuid and getresgid, which
were always storing 16 bits even if the uid type was 32 bits.

  linux-user: Implement sendmmsg syscall

Glibc when built for newer kernels assumes that the sendmmsg syscall is
available. Without it, dns resolution simply fails to work.

Wrap the syscall with existing infrastructure so that we don't have a host
dependency on sendmmsg.

To avoid locking the same area of guest memory twice (which will break if
DEBUG_REMAP is defined) we pull the lock/unlock part of do_sendrecvmsg()
out into its own function so the actual implementation can be shared.

[PMM: add recvmmsg support;
 handle errors (which also implies support for non-blocking operations);
 cap the vector length as the kernel implementation does;
 don't lock guest memory twice;
 support MSG_WAITFORONE flag]

  linux-user: translate signal number on return from sigtimedwait

On success, sigtimedwait() returns a signal number that needs to be
translated from a host value to a target value.

This change also fixes issues with sigwait (that is implemented using
sigtimedwait()).

  linux-user: set minimum kernel version to 2.6.32

Popular glibc based distributions[1] require minimum
2.6.32 as kernel version. For some targets 2.6.18
would be enough, but dropping so low would mean some
suboptimal system calls could get used.

Set the minimum kernel advertized to 2.6.32 for
all architectures but aarch64 to ensure working qemu
linux-user in case host kernel is older.
