	* test/runtest, test/tests/inc/test-deb359167,
	test/tests/inc/test-eom-align, test/tests/manpages/test-manpages:
	Load common.sh via absolute path, otherwise some /bin/sh
	(e.g. dash) can't load it.

	* uip/Makefile.in, uip/new.c, test/tests/new/test-basic: Add new
	program, and fn/fp/unseen symlinks.

	* test/{runtest,setup-test}: Move MH profile under Mail directory
	so each test script will have its own to muck with, if needed.

	* h/Makefile.in, h/crawl_folders.h, sbr/Makefile.in,
	sbr/crawl_folders.c, uip/folder.c: Extract the folder crawling
	code from folder.c into new crawl_folders function, using a
	callback to assemble the folder info in folder.c.  Drop compare
	function and use strcmp instead.  Rename addfold and addir to
	add_folder and add_children (add dir vs. add folder?
	confusing names).
