little util to scan mailboxes for any and every address they contain.

	* tests/data/getaddr.pl: little util to scan mailboxes for any and
	every address they contain.

	* tests/message/test2.c (main): Added a bunch of stuff to test
	decoding/reencoding/etc of internationalised addresses.

	* tests/message/lib/address-data.h: Copy of some unicode/other
	testing data.  **Beware** of editing this file in emacs, it'll
	probably try and convert all the characters to something
	unusable.

	* tests/lib/camel-test.c (camel_test_break): Add a debugger hook
	point.

	* camel-mime-utils.c (quoted_encode): Check for space and convert
	to _ separately.
	(header_decode_mailbox): Fixed the 'check comments for realname'
	code, problem was the domain getting code was skipping all
	whitespace/comments before we could get a look-in.  This is
	approximate but fairly robust.
	(header_decode_text): Dont use the c-type isspace func here, we
	want a specific whitespace only.
	(header_decode_text): If we have decoded words next to each other,
	do not insert whitespaces between them, which is what rfc2047 requires.
	(header_decode_text): Make c unsigned too.
