Remove some warnings with IBM'S mathlib

[Andreas Jaeger]

I get a number of warnings in the math code.  Here's a patch that I'll
commit later to remove some of them.

Still open are warnings like:
../sysdeps/ieee754/dbl-64/sincos32.c:111: warning: no previous prototype for `__c32'
../sysdeps/ieee754/dbl-64/sincos32.c:136: warning: no previous prototype for `__sin32'
../sysdeps/ieee754/dbl-64/sincos32.c:160: warning: no previous prototype for `__cos32'
../sysdeps/ieee754/dbl-64/doasin.c:40: warning: no previous prototype for `__doasin'

I propose to add all the declarations to math_private.h.  Or is there
a better way to do this?

	* sysdeps/ieee754/dbl-64/e_asin.c: Include "math_private.h" for
	internal prototypes.
	* sysdeps/ieee754/dbl-64/s_atan.c: Likewise.
	* sysdeps/ieee754/dbl-64/e_sqrt.c: Likewise.
	* sysdeps/ieee754/dbl-64/e_remainder.c: Likewise.
	* sysdeps/ieee754/dbl-64/e_pow.c: Likewise.
	* sysdeps/ieee754/dbl-64/e_log.c: Likewise.
	* sysdeps/ieee754/dbl-64/e_exp.c: Likewise.
	* sysdeps/ieee754/dbl-64/e_atan2.c: Likewise.
	* sysdeps/generic/e_rem_pio2l.c: Likewise.
	(__ieee754_rem_pio2l): Fix prototype.

	* math/math_private.h (__copysign): Add internal prototype.
