Joseph Myers 55eb99e9a9 Implement C23 log10p1
C23 adds various <math.h> function families originally defined in TS
18661-4.  Add the log10p1 functions (log10(1+x): like log1p, but for
base-10 logarithms).

This is directly analogous to the log2p1 implementation (except that
whereas log2p1 has a smaller underflow range than log1p, log10p1 has a
larger underflow range).  The test inputs are copied from those for
log1p and log2p1, plus a few more inputs in that wider underflow
range.

Tested for x86_64 and x86, and with build-many-glibcs.py.
