* camel-simple-data-wrapper.c (construct_from_stream): If we
already have been constructed, unref our content.
(write_to_stream): Check we've been constructued, and change for
stream api changes.
* camel-mime-parser.c: Removed exception stuff.
* md5-utils.c (md5_get_digest_from_stream): repaired.
* camel-mime-message.c: Remove exception from write_to_stream, and
fix, and fix formatting.
* providers/sendmail/camel-sendmail-transport.c (_send_internal):
Fix for stream changes.
* providers/pop3/camel-pop3-store.c (camel_pop3_command): Fixes
for stream changes.
* providers/mbox/camel-mbox-folder.c, and elsewhere, fix all
stream api changes.
(mbox_append_message): Use stream_close() now its back.
(mbox_append_message): unref the from filter.
* camel-stream-mem.c: And here.
* camel-stream-fs.[ch]: Here too.
* camel-stream-filter.c: Likewise. This is getting tedious.
* camel-stream-buffer.c (stream_write): Fix a few little problems.
(stream_close): Reimplmeent.
(camel_stream_buffer_read_line): Slightly more efficient version,
that also only allocates the right amount of memory for strings.
* camel-seekable-substream.c: Likewise.
* camel-seekable-stream.[ch]: Remove exceptions, fix formatting,
changes for stream (re)fixes. set_bounds returns an error.
* camel-stream.[ch]: Remove exceptions. Make flush and reset return
an error code, repair all the screwed up formatting, and put back
close.
* camel-mime-part-utils.c
(camel_mime_part_construct_content_from_parser): And here.
* camel-mime-part.c (camel_mime_part_set_content): And this too.
(write_to_stream): Fixed for stream changes.
* camel.h: Fixed.
* providers/vee/camel-vee-folder.c (vee_search_by_expression):
Implement. Performs an intersection of the two searches.
(camel_vee_folder_finalise): Unref search folders.
(vee_append_message): Implement append.
