Move compression file name utilities to lib/

This makes more sense as a home for plain file name manipulation
utilities.  I also merged `include/comp_src.h.in` into
`lib/compression.c`, because structure definitions (as opposed to
declarations) don't belong in header files.

* src/compression.c: Move to ...
* lib/compression.c: ... here.  Remove unnecessary `pipeline.h` include.
* src/compression.h: Move to ...
* lib/compression.h: ... here.  Update positioning of all includes.
* lib/Makefile.am (libman_la_SOURCES): Add `compression.c` and
`compression.h`.
* lib/README: Add `compression.*`.
* src/Makefile.am (lexgrog_SOURCES, man_SOURCES, man_recode_SOURCES,
mandb_SOURCES): Remove `compression.c` and `compression.h`.

* include/comp_src.h (comp_list): Move to ...
* lib/compression.c (comp_list): ... here.  Update all references.
* include/manconfig.h (struct compression, comp_list): Move to ...
* lib/compression.h (struct compression, comp_list): ... here.  Add
includes where necessary.
* Makefile.am (noinst_HEADERS): Remove `include/comp_src.h`.
