logb: Provide replacement and workarounds.
* lib/math.in.h (logb): Ensure declaration. Replace if REPLACE_LOGB
is 1.
* lib/logb.c: New file.
* m4/logb.m4 (gl_FUNC_LOGB_WORKS): New macro.
(gl_FUNC_LOGB): Invoke it. Set HAVE_LOGB, REPLACE_LOGB.
* m4/math_h.m4 (gl_MATH_H_DEFAULTS): Initialize REPLACE_LOGB.
* modules/math (Makefile.am): Substitute REPLACE_LOGB.
* modules/logb (Files): Add lib/logb.c.
(Depends-on): Add isfinite, frexp, isnand.
(configure.ac): Compile the replacement code logb.c if needed.
* tests/test-math-c++.cc: Check the declaration of logb.
* doc/posix-functions/logb.texi: Mention the replacement and the bug
with subnormal numbers.
