Brooks Davis 4d6722ec69 libc: don't try to export mexitcount
This requires that mcount.c be compiled with -DGUPROF and we provide no
mechanism to do so.

Warner Losh dc36d6f9bb lib: Remove ancient SCCS tags.
Remove ancient SCCS tags from the tree, automated scripting, with two
minor fixup to keep things compiling. All the common forms in the tree
were removed with a perl script.

Warner Losh 559a218c9b libc: Purge unneeded cdefs.h
These sys/cdefs.h are not needed. Purge them. They are mostly left-over
from the $FreeBSD$ removal. A few in libc are still required for macros
that cdefs.h defines. Keep those.

Ed Maste 05bc9aa78f mcount: tidy up ANSIfication
libc/gmon's mcount was ANSIfied in r124180, with libkern following over
a decade later, in r325988, but some minor discrepancies remained.
Update libc/gmon's mexitcount to an ANSI C function definition, and use
(void) for libkern-only functions that take no arguments.

Pedro F. Giffuni 8a16b7a18f General 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.

Warner Losh 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.

Brooks Davis af6f4233fd Replace the last non-optional use of sbrk() in the tree with mmap().
All gmon want's is a region of memory without the overhead of malloc().
Just mapping some pages with mmap is an easy way to accomplish this.

Marcel Moolenaar 8876613dc5 Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}
if not already defined. This allows building libc from outside of
lib/libc using a reach-over makefile.

A typical use-case is to build a standard ILP32 version and a COMPAT32
version in a single iteration by building the COMPAT32 version using a
reach-over makefile.

Marcel Moolenaar af448c52e4 Simplify the calculation of s_scale by rewriting the FP expression to
use uintmax_t instead of float and thereby eliminating the need for
a non-FP version.

Tested on: amd64, ia64 & powerpc (book-E)

Marcel Moolenaar c5e0ba5fe4 On powerpc, calculate s_scale using the non-FP version previously
specific to hp300. Since FreeBSD does not support hp300, hp300 has
been removed from the condition altogether.

The FP version broke profiling on powerpc due to invalid results.
Casting to double instead of float resolved the issue, but with
Book-E not having a FP unit, the non-FP version looked preferrable.
Note that even on AIM hardware the FP version yielded an invalid
value for s_scale, so the problem is most likely with the compiler
or with the expression itself.

Peter Wemm b320e7fae7 For amd64, explicitly compile mcount.po, rather than copying mcount.o. We
need to compile it with -fno-omit-frame-pointers since the mcount code

Peter Wemm 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.

Mark Murray 4cd0119367 Do not use __progname directly (except in [gs]etprogname(3)).
Also, make an internal _getprogname() that is used only inside
libc. For libc, getprogname(3) is a weak symbol in case a
function of the same name is defined in userland.
