[PATCHv3 1/8] Prepare to convert _Complex cosine functions

[Paul E. Murphy]

These include formatting cleanups as requested by Joseph,
along with changelog cleanups.

Likewise, in a few files I have removed superfluous
parenthesis as part of the formatting cleanups.

This continues the discussion from

https://sourceware.org/ml/libc-alpha/2016-08/msg00516.html

This patch has no function changes, except to
ensure the git history correctly tracks the
changes to convert the double version of these
functions into a templated version.

	* s_cacos_template.c: Copy of s_cacos.c.
	* s_cacosh_template.c: Copy of s_cacosh.c.
	* s_ccos_template.c: Copy of s_ccos.c.
	* s_ccosh_template.c: Copy of s_ccosh.c.
