Update to 2.4.15. Extract of changes since .11:

	* gmime/gmime-encodings.h (GMIME_UUENCODE_LEN): Fixed to prevent
	possible buffer overflows.
	* configure.in: Bumped version to 2.4.14 and disabled
	strict-aliasing which causes bugs in GMime.
	* gmime/gmime-filter-crlf.c (filter_filter): Fixed bug #606875 by
	not trying to skip multiple characters per pass thru the loop when
	encountering the first '.' of a possible '..' sequence.
	* configure.in: Bumped version to 2.4.12
	* gmime/gmime-utils.c (g_mime_utils_decode_8bit): Make sure to
	always increment inptr as we force-convert it to ascii. Thanks to
	Damian Pietras for finding this bug.
	* gmime-2.4.pc.in: Moved -lz -lnsl, etc into Libs.private. Fixes
	bug #603273.
