lib: Split up huge src/guestfs.c into logical compilation units.

This file had grown by accretion to include:

 - code related to handles (now in src/handle.c)

 - safe allocation (src/alloc.c)

 - debug, errors, warnings (src/errors.c)

 - private data (src/private-data.c)

 - miscellaneous functions (src/canonical-name.c, src/utils.c)

This commit also removes about a dozen #include files which were
probably not really used.

This is just code motion.
