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:

libm_hidden_def expand the parameters and do not require an extra layer
of macros.
These were the last 3 files in math/ still using hidden_def().
* math/w_exp_compat.c: Replace hidden_def with libm_hidden_def..
* math/w_expl_compat.c: Likewise.
* math/w_exp_template.c: Likewise. Remove hidden_def_x.

This patch converts libm function implementations in math/ from using
weak_alias to using libm_alias_ldouble to define public function
names, in cases where it would be appropriate to define _Float128 /
_Float64x aliases for those functions as well (in cases where either
or both of those types exist and have the same ABI as long double).
This eliminates many ldbl-opt wrappers round these function
implementations.
Tested for x86_64, and with build-many-glibcs.py. All installed
stripped shared libraries are unchanged except for libm.so on
powerpc64le. As noted for a previous patch, powerpc64le's use of
ldbl-opt means various long double functions get defined using
long_double_symbol which gives them an explicit symbol version in the
object files, and this patch results in some such functions using
weak_alias instead (because powerpc64le never had a previous version
of these functions for long double = double); both produce a valid
libm.so with the same public symbols at the same versions, but macros
expanding to call weak_alias is cleaner in this case.
