Make more libm functions into weak aliases.

Many libm functions define the function as __<func> and then define
<func> as a weak alias.  This is not at all limited to cases where
there is an internal call that has namespace reasons to need to call
__<func> instead of <func>.

The common macros for creating libm function aliases work on the basis
of public function names all being aliases; that is, they define
aliases for functions using the above pattern.  Thus, where a function
just defines the public name <func> directly, changing that to be a
weak alias enables a subsequent conversion to the common macros to
retain the exact existing symbols (and so be testable by comparison of
stripped binaries).

This patch converts many existing functions to use the weak alias
pattern, as preparation for subsequent conversions to common macros.
I do expect that _FloatN/_FloatNx function aliases will end up needing
new variants of the common macros that do *not* create the original
float / double / long double name of a function - for cases where that
name is created specially to give it a particular symbol version, for
example - but for functions that can use the most common macros to
create all the public names as aliases, it makes sense for them to do
so.

Regarding the Bessel function wrappers in this patch: only float and
double wrappers are changed because the long double wrappers already
used the weak alias pattern.

Tested for x86_64, and with build-many-glibcs.py.
