[patch] cygport-0.2.9 hooks for additional prep, install customization

[Charles Wilson <cygwin at cwilson dot fastmail dot fm>]

Forward port to latest release. Only change from previous, is that 
current cygport CVS now checks for ${SRCDIR} before cd'ing into it, so 
that part of the previous patch has been removed, below.

For further history and justifiation of this patch, see 
http://cygwin.com/ml/cygwin/2007-01/msg00110.html and follow the 
embedded links and threads.

	* cygport.in (src_prep_init_hook): new (empty) function
	(src_prep_fini_hook): ditto
	(src_prep): call src_prep_init_hook() after setting up the
	cygport directory structure, unpacking all entities in SRC_URI,
	but before applying any of the patches in PATCH_URI, and before
	mirroring the origsrc directory to the src directory, or
	applying the .src.patch and .cygwin.patch to the src directory).
	(src_prep): call src_prep_fini_hook() after doing ALL of the
	above.
	(src_install_init_hook): new (empty) function
	(src_install_fini_hook): new (empty) function
	(main) [case inst*]: call src_install_init_hook FIRST, then
	other automated installation steps, then src_install_fini_hook
	LAST
	(main): export all hook functions.
