Log Message:
Update to 2.2.22:

	* configure.in: Bumped version to 2.2.22
	* src/uudecode.c (uudecode): Don't base64 decode the

	* COPYING: Fixed to reference LGPL v2.1
	* gmime/gmime-common.h: Removed unused prototypes.
	* gmime/gmime-message.c (g_mime_message_add_recipient): Change
	'type' argument to const char *.
	(g_mime_message_add_recipients_from_string): Same.
	* gmime/gmime-utils.h (GMIME_QP_ENCODE_LEN): Add an extra byte for
	\n in the case of quoted_encode_close(). Thanks to Peter
	Bloomfield for discovering this.
	* gmime/internet-address.c (decode_mailbox): Prevent reading past
	the end of the input string.
	* examples/basic-example.c: Fixed to use GMimeSignatureValidity.
	* gmime/gmime-multipart-encrypted.c (g_mime_multipart_encrypted_encrypt):
	Don't use deprecated functions.
	* gmime/gmime-stream.c (stream_eos): Fixed a typo.
	* mono/StreamWrapper.cs: Allow seeking to position 0 for
	GMimeStreamFilter. Thanks to Debajyoti Bera for this patch.
	* README: Bumped version
	* configure.in: Bumped version to 2.2.21
	* gmime/gmime-parser.c: Check parser_step() against
	GMIME_PARSER_STATE_ERROR rather than -1 in case the value ever
	changes.
	(struct _GMimeParserPrivate): Changed state to be 16bit int
	instead of a 26bit int which apparently cannot be set to -1 on
	Solaris. Fixes bug #534301.
	(parser_step_headers): Fixed a corner-case where a read boundary
	fell between the \n and \t of a folded header.
	* README: Bumped version
	* configure.in: Bumped version to 2.2.20
	* gmime/gmime-stream-buffer.c (stream_read): Break if
	g_mime_stream_read() returns 0 as well (meaning EOF, no more data
	to read) and don't keep looping. Fixes bug #533331.
	* README: Bumped version
	* configure.in: Bumped version to 2.2.19
	* gmime/gmime-parser.c (parser_step_headers): Fix for CRLF encoded
	input.
