Add locking to camel_nntp_get_grouplist_from_server().

2001-07-06  Joe Shaw  <joe@ximian.com>

	* providers/nntp/camel-nntp-grouplist.c: Add locking to
	camel_nntp_get_grouplist_from_server().

	* providers/nntp/camel-nntp-resp-codes.h: Added
	NNTP_EXTENSIONS_SUPPORTED (202).

	* providers/nntp/camel-nntp-store.c (camel_nntp_store_get_extensions):
	Check for both NNTP_LIST_FOLLOWS and NNTP_EXTENSIONS_SUPPORTED from
	a LIST EXTENSIONS request. (Dunno if NNTP_LIST_FOLLOWS ever comes
	out of this, but that's what was already there...) Also, put some
	locking around it.
	(finalize): e_mutex_destroy() the command lock
	(camel_nntp_store_init): e_mutex_new() the command lock.

	* providers/nntp/camel-nntp-store.h: Add locking macros.
