Fix libm mpone, mptwo namespace (bug 17616).
libm uses symbols mpone and mptwo for internal purposes.  This patch
moves them to the implementation namespace (__mpone and __mptwo).

Tested for x86_64 (testsuite, and that installed stripped shared
libraries are unchanged by the patch).

	[BZ #17616]
	* sysdeps/ieee754/dbl-64/mpa.c (mpone): Rename to __mpone.
	(mptwo): Rename to __mptwo.
	(__inv): Use __mptwo instead of mptwo.
	* sysdeps/ieee754/dbl-64/mpa.h (mpone): Rename to __mpone.
	(mptwo): Rename to __mptwo.
	* sysdeps/ieee754/dbl-64/mpatan.c (__mpatan): Use __mpone instead
	of mpone and __mptwo instead of mptwo.
	* sysdeps/ieee754/dbl-64/mpatan2.c (__mpatan2): Use __mpone
	instead of mpone.

	* sysdeps/ieee754/dbl-64/sincos32.c (__c32): Use __mpone instead

	(__mpranred): Use __mpone instead of mpone.

	variable.
