24b6515d87 Add libm_alias_*_other_r macros. 
Some libm functions are unable to use the generic alias macros such as
libm_alias_double because they have special symbol versioning
requirements for the main float, double or long double public names.

To facilitate adding _FloatN / _FloatNx function aliases in future,
it's still desirable to have generic macros those functions can use as
far as possible.  This patch adds macros such as
libm_alias_double_other, which only define names for _FloatN /
_FloatNx aliases, not for float / double / long double.  As present,
all these new macros do nothing, but they are called in the
appropriate places in macros such as libm_alias_double.  This patch
also arranges for lgamma implementations, and the recently added
optimized float function implementations, to use the new macros to
make them ready for addition of _FloatN / _FloatNx aliases.

Tested for x86_64, and tested with build-many-glibcs.py that installed
stripped shared libraries are unchanged by this patch.

72d3d28108 New symbol version for logf, log2f and powf without SVID compat 
This patch changes the logf, log2f and powf error handling semantics
to only set errno accoring to POSIX rules. New symbol version is
introduced at GLIBC_2.27.

The old wrappers are kept for compat symbols.

ia64 needed assembly change to have the new and compat versioned
symbol map to the same function.

All linux libm abilists are updated.

f67d78192c Move wrappers to libm-compat-calls-auto 
This commit moves one step towards the deprecation of wrappers that
use _LIB_VERSION / matherr / __kernel_standard functionality, by
adding the suffix '_compat' to their filenames and adjusting Makefiles
and #includes accordingly.

New template wrappers that do not use such functionality will be added
by future patches and will be first used by the float128 wrappers.
