new file, groups mime-part related utils. Meant to be used by providers

1999-08-26  bertrand  <Bertrand.Guiheneuf@aful.org>

	* camel/camel-mime-part-utils.c: new file, groups
	mime-part related utils. Meant to be used by providers
	subclassing MimeMessage.
	(camel_mime_part_construct_headers_from_stream):
	(camel_mime_part_construct_content_from_stream):
	no more useless temporary hash table.

	* camel/camel-mime-part.c (_construct_from_stream): calls
	mime-part-utils functions now.

	* camel/gmime-utils.c (_store_header_pair_from_string):
	do not use hash table to store header, use an array instead.


* MimePart cleanup. Not complete yet. Content must not be
parsed when constructing but only when content object is requested.
Default implementation will keep content in a stream.
