Move all includes from /usr/include/….h to /usr/include/osmocom/gtp/….h to be more consistent with other Osmocom projects, and to not "pollute" the top include directory if we add more header files. Also the new directory structure makes more obvious, which headers are public and which ones aren't. Adjust libgtp.pc.in so both #include <gtp.h> (legacy) and #include <osmocom/gtp/gtp.h> can be used. Related: OS#6373 Change-Id: If7e01c61168819bf7120667344e40c857da5490b
