51369649b0 sys: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

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
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

646c5b4840 Replace the WEAK_ALIAS() alias with the WEAK_REFERENCE() alias. Use it and
get rid of the __CONCAT and CNAME macros.

0f3a4d8051 libc: Access _logname_valid more efficiently.
The variable _logname_valid is not exported via the version script;
therefore, change C and i386/amd64 assembler code to remove indirection
(which allowed interposition). This makes the code slightly smaller and
faster.

Also, remove #define PIC_GOT from i386/amd64 in !PIC mode. Without PIC,
there is no place containing the address of each variable, so there is no
possible definition for PIC_GOT.

461d4da338 Remove _ARCH_INDIRECT, it was the glue to enable having both hardware
and software versions of the floating point code in libm.  The runtime
selection was done by reading the hw.floatingpoint sysctl via
__get_hw_float().

8d19a0584b Don't use ## to concatinate to two things that don't together make a C token.
Two tokens that don't together form a vaid preprocssor token cannot be
pasted together using ANSI-C token concatinatation.  GCC 3.2's cpp, at least,
produces the desired result w/o using "##".

66422f5b7a Initiate deorbit burn for the i386-only a.out related support. Moves are
under way to move the remnants of the a.out toolchain to ports.  As the
comment in src/Makefile said, this stuff is deprecated and one should not
expect this to remain beyond 4.0-REL.  It has already lasted WAY beyond
that.

Notable exceptions:
gcc - I have not touched the a.out generation stuff there.
ldd/ldconfig - still have some code to interface with a.out rtld.
old as/ld/etc - I have not removed these yet, pending their move to ports.
some includes - necessary for ldd/ldconfig for now.

Tested on: i386 (extensively), alpha

be16a3aba0 Fixed the profiling version ALTENTRY(). Again. The previous version
didn't set up the frame pointer before calling mcount, and then jumped
to the wrong place in ENTRY() to defeat the point of the jump.

a862685541 Fixed longstanding profiling bug. The frame pointer wasn't set up
for syscalls, so one frame was lost in backtraces from syscalls.
This is handled better in the kernel by using a different mcount
entry point for profiling before the frame pointer is set up.

Expand RCSID().

Use .p2align instead of the ambiguous .align.

Added idempotency ifdef.

Removed unused macros ALTENTRY(), ALTASENTRY(), ASENTRY(), _MID_ENTRY.

Cleaned up formatting.

644ba7e84e Cloned src/lib/libc/i386/DEFS.h to create <machine/asm.h> for the i386.
The former file was too hard to get at from other parts of the src tree
and will go away.
