Add an "authtypes" hash table to CamelImapStore recording the supported
* providers/imap/camel-imap-store.c: Add an "authtypes" hash table to CamelImapStore recording the supported authtypes. (connect_to_server): Record supported authtypes in the authtypes hash rather than the capabilities bitmask, since now the IMAP code is no longer responsible for keeping track of which authtypes we support. (query_auth_types): Use camel_sasl_authtype_list to get the SASL-supported authtypes. (try_auth): New function to try a SASL auth mechanism. Sort of formerly imap_try_kerberos_v4_auth. (imap_connect): Get rid of the krb4-specific bits and genericize them for any SASL authtype. * providers/imap/Makefile.am: Remove camel-imap-auth.[ch] (moved into camel-imap-store.c since it's now constant size) and the KRB4_CFLAGS and KRB4_LDFLAGS references. svn path=/trunk/; revision=8463
