Some applications use /proc/$$/... (where $$ is the own pid) instead of
/proc/self/... to refer to their own proc files. Extend the interception
for open and readlink to handle this case. Also, do the same interception
in readlinkat.

Commit c0d472b12e accidentally dropped the definition of
__NR_SYS_utimensat even though its use is guarded by
CONFIG_UTIMENSAT, not CONFIG_ATFILE. Some older glibc don't
have utimensat() (even if they have the other *at() functions).
Fix this by correctly cleaning up the sys_utimensat()
implementation and #defines, so that we always provide the
syscall if needed whether we're doing it via glibc or not.

In the ARM implementation of cpu_signal_handler(), set is_write
correctly using the FSR value which the kernel passes us in the
error_code field of uc_mcontext. Since the WnR bit of the FSR was
only introduced in ARMv6, this means that v5 cores will continue
to behave as before this patch, but they are not really supported
as hosts for linux-user mode anyway since they do not have the
modern behaviour for unaligned accesses.

Previous implementation has failed to take into account different value of
SOCK_NONBLOCK on target and host, and existence of SOCK_CLOEXEC.
The same conversion has to be applied both for do_socket and do_socketpair,
so the code has been isolated in a static inline function.
enum sock_type in linux-user/socket.h has been extended to include
TARGET_SOCK_CLOEXEC and TARGET_SOCK_NONBLOCK, similar to definition in libc.
The patch also includes necessary code style changes (tab to spaces) in the
header file since most of the file has been touched by this change.
