They are both used by __libc_freeres to free all library malloc
allocated resources to help tooling like mtrace or valgrind with
memory leak tracking.
The current scheme uses assembly markers and linker script entries
to consolidate the free routine function pointers in the RELRO segment
and to be freed buffers in BSS.
This patch changes it to use specific free functions for
libc_freeres_ptrs buffers and call the function pointer array directly
with call_function_static_weak.
It allows the removal of both the internal macros and the linker
script sections.
Checked on x86_64-linux-gnu, i686-linux-gnu, and aarch64-linux-gnu.

I used these shell commands:

I then removed trailing white space from math/tgmath.h,
support/tst-support-open-dev-null-range.c, and
sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following
obscure pre-commit check failure diagnostics from Savannah. I don't
know why I run into these diagnostics whereas others evidently do not.

We stopped adding "Contributed by" or similar lines in sources in 2012
in favour of git logs and keeping the Contributors section of the
glibc manual up to date. Removing these lines makes the license
header a bit more consistent across files and also removes the
possibility of error in attribution when license blocks or files are
copied across since the contributed-by lines don't actually reflect
reality in those cases.
Move all "Contributed by" and similar lines (Written by, Test by,
etc.) into a new file CONTRIBUTED-BY to retain record of these
contributions. These contributors are also mentioned in
manual/contrib.texi, so we just maintain this additional record as a
courtesy to the earlier developers.
The following scripts were used to filter a list of files to edit in
place and to clean up the CONTRIBUTED-BY file respectively. These
were not added to the glibc sources because they're not expected to be
of any use in future given that this is a one time task:

Bug Fixes:
* nss/nsswitch.c (_res): Remove redundant variable definition.
The real one is in resolve/res_init.c, and having both prevents
using -fno-common when building the shared library.
* sunrpc/rpc_prot.c (_null_auth): Same. Original is in rpc_common.c.
* sysdeps/unix/sysv/linux/alpha/brk.S: When PIC, define __curbrk as
a .bss object not a COMMON symbol.
* sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/bsd-setjmp.S: Must load
$gp before referencing __sigsetjmp symbol. Retain LITUSE for same.
Optimizations:
* sysdeps/alpha/strlen.S: Rearrange first-word setup and thense the
main loop for better dual-issue on EV5. Rearrange binary search to
pipeline better and trim one instruction.
Cosmetic Changes:
* time/localtime.c (localtime_r): Move lock declaration back next to
the comment where it was before the 960724 change.
* INSTALL, manual/maint.texi: alpha-gnu-linux -> alpha-ANYTHING-linux.
The second word is supposed to be the hardware manufacturer.
* sysdeps/alpha/_mcount.S: Retain LITUSE for __mcount.
* sysdeps/alpha/setjmp.S: Retain LITUSE for __sigsetjmp_aux.
* sysdeps/alpha/divrem.h: More local labels, retain LITUSE for _mcount.
* sysdeps/alpha/alphaev5/add_n.S, sysdeps/alpha/alphaev5/lshift.S,
sysdeps/alpha/alphaev5/rshift.S, sysdeps/alpha/alphaev5/sub_n.S:
Same cleanups as with EV4 GMP stuff.

pointer as __const.
* string/tester.c (main): Test stpncpy.
* sysdeps/generic/stpncpy.c (__stpncpy): Fix so it works without
segfault when called with an N that is not a multiple of four and
src[N-1]=='\0'.
* misc/syslog.c (LogType): New variable.
(openlog): If connect() with SOCK_DGRAM fails with EPROTOTYPE,
try again with SOCK_STREAM (the Linux syslogd uses a socket of the
latter type).
(vsyslog): When LogType==SOCK_STREAM, also send ASCII NUL
terminator as a record-delimiter. If __send(LogFile) fails,
call closelog() so logfile gets re-opened next time.
Wed Aug 7 15:15:14 1996 Ulrich Drepper <drepper@cygnus.com>
* elf/dl-open (_dl_open): Add cast to avoid warning.
* manual/memory.texi: Improve some examples to give readers better
advice: Use `stpcpy' instead of `strcat' if possible.
* manual/string.texi: Document `strtok_r' and `strtok'.
* sunrpc/Makefile: Move `+gccwarn' definition before inclusion
of Makeconfig.
[$(cross-compiling)=no]: Change test before making librpcsvc
to this from $(cross-compile).

Tue Aug 6 14:27:11 1996 Ulrich Drepper <drepper@cygnus.com>

(rtld-routines): ...from here. This should make static linking
work again.
* locale/setlocale.c: Add local variable `lock' and add code to
`setlocale' to avoid simultaneous changing of global data.
* catgets/catgets.c (catopen): Use `__strdup' instead of `strdup'.
* catgets/open_catalog (__open_catalog): Use `__stpcpy', `__open',
`__fstat', `__read', `__mmap', `__munmap' and `__close' instead
of unprotected names.
* stdlib/strtol.c [!QUAD] (ULONG_MAX, LONG_MAX): Define these
macros if they are not available.
(WEAKNAME): New macro to declare argument as weak.
Define function with __ prefix and add normal name as weak alias.
* sysdeps/posix/euidaccess.c (S_IROTH, S_IWOTH, S_IXOTH): Defines
these macros if not already available based on R_OK, W_OK, and
X_OK.
Tue May 21 18:48:46 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>

__need_va_list before including <stdarg.h>.
* Makerules (o-iterator): Use $(object-suffixes-left) instead
of $(object-suffixes) to produce repetitions; this is used for other
lists than just that one.
[versioned]: Use $(o-iterator) properly.
* sysdeps/unix/sysv/linux/Implies: Include `gnu'.

* locale/C-monetary.c: Default value for mon_decimal_point should be
'.'.
* stdio-common/printf.h: Remove Linux libc compatibility stuff.
Add `extra' flag. Currently used in __printf_fp.
* stdio-common/printf_fp.c (__guess_grouping): Renamed from
`guess_grouping' and extend visibility to extern. This function
is now used in `strfmon'.
(__printf_fp): Recognize new bit flag in info struct. This
triggers to use the grouping information and decimal point from
the LC_MONETARY category instead of the LC_NUMERIC category.
* stdio-common/vfprintf.c (process_arg): Correct major bug. In
`complicated' loop we must not use the varargs because the args
are already available in the ARGS_VALUE array.
* stdlib/Makefile (headers): Add monetary.h.
(routines): Add strfmon.
* stdlib/monetary.h: New file. Header for strfmon function.
* stdlib/strfmon.c: New file. Implement strfmon function to print
monetary amounts according to current locale's rules.
* sysdeps/unix/sysv/linux/i386/sys/vm86.h: The kernel header is
now (>= Linux-1.3.100) called <asm/vm86.h>.
