	* context.h: New member signers_len.  * signers.c
	(gpgme_signers_clear): Require that signers are non-NULL with
	assertion.  Use signers_len to determine how much keys to release.
	Add documentation.
	(gpgme_signers_add): Use signers_len to determine if the buffer is
	large enough.  Use xtryrealloc rather than xtrymalloc and copying.
	Add documentation.
	(gpgme_signers_enum): Use signers_len to determine if key is
	available.  Add documentation.
