documentation: convert "diffcore" and "repository-layout" to man pages

This patch renames the following documents and at the same time converts
them to the man format:

diffcore.txt          -> gitdiffcore.txt		(man section 7)
repository-layout.txt -> gitrepository-layout.txt	(man section 5)

Other documents that reference the above ones are changed accordingly.
