[PATCH 6/7] Include wchar.h and wctype.h unconditionally

[Yao Qi <yao@codesourcery.com>]

As gnulib modules wchar and wctype is imported, we can include wchar.h
and wctype.h unconditionally.  This patch is also to remove HAVE_WCHAR_H
check.

gdb:

2014-11-15  Yao Qi  <yao@codesourcery.com>

	* gdb_wchar.h: Include wchar.h and wctype.h.
	[HAVE_ICONV && HAVE_BTOWC]: Don't check HAVE_WCHAR_T and don't
	include wchar.h and wctype.h.
	Don't check HAVE_WCHAR_H.
