added camel-mbox-provider.c to the mbox provider sources.

2000-01-21  bertrand  <bertrand@helixcode.com>

	* camel/providers/mbox/Makefile.am (libcamelmbox_la_SOURCES):
	added camel-mbox-provider.c to the mbox provider
	sources.

	* camel/providers/mbox/camel-mbox-provider.c:
	provider registration code.

	* camel/providers/mbox/camel-mbox-folder.c (_get_message_count): implemented
	(_append_message): implemented

	* camel/providers/mbox/camel-mbox-parser.c (initialize_buffer):
	use \0 to mark the end of the buffer.
	(read_next_buffer_chunk): ditto.
	(read_header): test the presence of a \0 instead of
	reading the eof field
	(read_message_begining): idem.
	(camel_mbox_parse_file): idem.
	Remove the eof field from the parser
	structure.
	(read_next_buffer_chunk): removed some nasty bugs
	again.
