Build e-dbhash.[hc]

2000-11-07  JP Rosevear  <jpr@helixcode.com>

	* Makefile.am: Build e-dbhash.[hc]

	* e-dbhash.[hc]: New routines to manage a db database on disk that
	contains md5 hashed data and indexed by uids.  Provides comparison
	functions and such so the caller does not have to do the md5 bits.

2000-11-07  JP Rosevear  <jpr@helixcode.com>

	* backend/pas/pas-book.h: Update PASRequest structure

	* backend/pas/pas-book.c (impl_Evolution_Book_get_changes): update param name
	(pas_book_queue_get_changes): Use PASRequest change_id slot

	* backend/pas/pas-backend-file.c (pas_backend_file_book_view_copy):
	Properly copy change_id and change_context
	(pas_backend_file_book_view_free): Free change_id/change_context
	(pas_backend_file_changes_foreach_key): Callback to figure out the
	deleted cards
	(pas_backend_file_changes): Use new e-dbhash stuff to implement.
	Write out updated hash

	* backend/idl/addressbook.idl: Rename get_changes param
