Completely new implementation of NNTP.

2001-11-30  Not Zed  <NotZed@Ximian.com>

        * providers/nntp/camel-nntp-*.c:

        Completely new implementation of NNTP.

        Doesn't support subscriptions yet (lists all folders), but should
        be more reliable (faster?), and has an integrated cache.

        * camel-exception.c (camel_exception_new): Use e_memchunks for
        exception blocks.
        (camel_exception_free): Same.

        * camel-data-cache.[ch]: New object for managing on-disk caches of
        anything that can be stored in a camel-stream.

        * camel-file-utils.c (camel_file_util_mkdir): New function, just a
        nicer place to put this (than camel-store), should be removed from
        camel-store.
        (camel_file_util_safe_filename): New function to url-encode a
        filename.

        * camel-mime-parser.c (drop_states): New func to drop the parser
        state to initial state.
        (folder_scan_init_with_fd):
        (folder_scan_init_with_stream): Call above func to reset state if
        the stream is changed on us so we can change streams to reuse a
        parser object.
