(_close): Update the summary's mbox_file_size and mbox_modtime before writing it to disk. * providers/mbox/camel-mbox-summary.c (camel_mbox_summary_save, camel_mbox_summary_load): Wow. I must have been tired when I wrote this code. First, the comparison bug above. Second, it was using ntohs and htons instead of ntohl and htonl. Third, I was reading the status flag byte in two different places and thus getting out of sync. Fourth, it was writing out field_length bytes of each header field after having converted field_length to network byte order, resulting in lots of random crap being appended, and the summary files being huge. (Fortunately, since the size/modtime comparison was biffed, the garbage summary read from disk was always immediately discarded.) * providers/mbox/camel-mbox-parser.c (camel_mbox_parse_file): fix an off-by-one error that caused the last-used UID to be reused if the summary file was regenerated.
