Two (not related to each other) refactorings:
Patches 1-12 split configure.ac into smaller files using the
m4_include mechanism.
Patches 13-15 split out parts of guestfs.pod (ie. guestfs(3)) into
three new manual pages:
guestfs-hacking(3) - how to extend and contribute to libguestfs
guestfs-internals(3) - architecture and internals
guestfs-security(3) - security and CVEs
Patch 16 is a minor tidy up of guestfs.pod.
Rich.
