Cleanup: split libtar header, move to sub directory

Some of the on-disk format internals are moved to a separate header
and some of the stuff from internal.h is moved to that format header.
C++ guards are added in addtion.

Everything PAX related is moved to pax_header.c, some internal
functions are marked as static.
