260ba0bff1 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.

Special thanks to Wind River for providing access to "The Duke of

starting point.

a2b76af9d7 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.

b00801215b 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().

a4e8bdb606 Preserve VFP state across signal delivery.
We don't have enouch space to store full VFP context within mcontext
stucture. Due to this:
 - follow i386/amd64 way and store VFP state outside of the mcontext_t
   but point to it. Use the size of VFP state structure as an 'magic'
   indicator of the saved VFP state presence.
 - teach set_mcontext() about this external storage.
 - for signal delivery, store VFP state to expanded 'struct sigframe'.

- in mcontext_t, rename newer used 'union __vfp' to equaly sized 'mc_spare'.
  Space allocated by 'union __vfp' is too small and cannot hold full
  VFP context.
- move structures defined in fp.h to more appropriate headers.
- remove all unused VFP structures.

e13d6f8b3f META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

fbb83e78c0 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.

0d1f91e8e1 Define several extra macros in bsd.sys.mk and sys/conf/kern.pre.mk, to
get rid of testing explicitly for clang (using ${CC:T:Mclang}) in
individual Makefiles.

Instead, use the following extra macros, for use with clang:
- NO_WERROR.clang       (disables -Werror)
- NO_WCAST_ALIGN.clang  (disables -Wcast-align)
- NO_WFORMAT.clang	(disables -Wformat and friends)
- CLANG_NO_IAS		(disables integrated assembler)
- CLANG_OPT_SMALL	(adds flags for extra small size optimizations)

As a side effect, this enables setting CC/CXX/CPP in src.conf instead of
make.conf!  For clang, use the following:

CC=clang
CXX=clang++
CPP=clang-cpp

d5a429b2e4 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.

ead754945e 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.
