lib: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Fix warnings found by -Wmising-variable-declarations.

This self-written compiler warning, which is hopefully going to be
committed into LLVM sources soon, warns about potentially missing
`static' keywords, similar to -Wmissing-prototypes.

- bin/pax: Move external declaration of chdname and s_mask into extern.h.
- bin/setfacl: Move setfacl.c-specific stuff out of setfacl.h.
- sbin/mount_fusefs: Remove char *progname; use getprogname().
- others: add `static' where possible.

Change lwp to int64_t as thr_pread_long() always uses a 64-bit value

Change lwp to int64_t as thr_pread_long() always uses a 64-bit value
in order to account for LP64 targets when cross-debugging on ILP32,
allowing r224683 to compile on ILP32.
Note that thr_p{read,write}_{long,ptr}() still incorrectly use the size
of the respective types on the host rather than that on the target when
accessing the target address space which still needs to be fixed. This
means that r224683 alone may not be sufficient to solve the problem it's
intended to fix when cross-debugging.

The tid member of struct pthread actually is long so read it as such.
Accessing it as an int causes failure on big-endian LP64, i.e. mips64be,
powerpc64 and sparc64.

Extend the td_thrinfo_t to include siginfo for the signal that stopped

Revert r181651, which changed the ABI, and use a temp variable instead.

Also, change th_p in td_event_msg_t from a pointer type to
psaddr_t, so that events also work when psaddr_t is widened.

Cleanup for WARNS 6.

Change the type of psaddr_t from void* to uintptr_t. A pointer
type cannot be made wider to allow ILP32 platforms to target
LP64 platforms.

Use linker set to collection all target operations.

Fix return value.

Use ps_linfo to retrieve LWP info, current it is used to retrieve
signal mask and pending signals.

Always clear thread info buffer to zero.

Add support for XMM registers in GDB for x86 processors that support
SSE (or its successors).
