Obsolete pow10 functions.
This patch obsoletes the pow10, pow10f and pow10l functions (makes them into compat symbols, not available for new ports or static linking). The exp10 names for these functions are standardized (in TS 18661-4) and were added in the same glibc version (2.1) as pow10 so source code can change to use them without any loss of portability. Since pow10 is deliberately not provided for _Float128, only exp10, this slightly simplifies moving to the new wrapper templates in the !LIBM_SVID_COMPAT case, by avoiding needing to arrange for pow10, pow10f and pow10l to be defined by those templates. Tested for x86_64, and with build-many-glibcs.py. * manual/math.texi (pow10): Do not document. (pow10f): Likewise.
