5e53a4f90f 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.

3876a56282 libpthread_db: undo the memset size change.
I inadvertedly soubled the size of the memset without noticing the
start address had changed. The size for the memset in pt_map_thread()
shouldn't actually match the reallocarray() so undo that part of r317200.

This is a re-commit of r317201 to clarify the log.

1f2b051d84 libthread_db: unsign map_len and use reallocarray(3).
Lengths are not negative, so map_len should be unsigned. Unsign the
corresponding indexes too and bring a small use of reallocarray(3).

Reorder the memset to be consistent with the realloc: it appears we
were only clearing half the memory in pt_map_thread().

ae824d80f2 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.

03fad2ad5f Allow psaddr_t to be widened by using thr_pread_{int,long,ptr},
where critical. Some places still use ps_pread/ps_pwrite directly,
but only need changed when byte-order comes into the picture.
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.

16b0c20c82 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.

3c1e38ea6e Add rudimentary support and stubs for libthr and libc_r on alpha, amd64,
i386, ia64 and sparc64. Add stubs for alpha, amd64, ia64 and sparc64 for
libpthread.

Restructure the source files to avoid unnecessary use of subdirectories
that also force us to use non-portable compilation flags to deal with
the uncommon compilation requirements (building archive libraries for
linkage into a shared library).

The libpthread support has been copied from the original local and
cleaned-up to make them WARNS=2 clean.
