pathspec: move doc to pathspec.h
Move the documentation from Documentation/technical/api-setup.txt
to pathspec.h as it's easier for the developers to find the usage
information beside the code instead of looking for it in another doc file.
Also documentation/technical/api-setup.txt is removed because the
information it has is now redundant and it'll be hard to keep it up to
date and synchronized with the documentation in the header file.
