[Libguestfs] [PATCH v6 41/41] UNFINISHED daemon: Reimplement most inspection APIs in the daemon, in OCaml.



Move the following APIs into the daemon, reimplemented in OCaml:

* inspect_os
* inspect_get_roots
* inspect_get_mountpoints
* inspect_get_filesystems
* inspect_get_format
* inspect_get_type
* inspect_get_distro
* inspect_get_package_format
* inspect_get_package_management
* inspect_get_product_name
* inspect_get_product_variant
* inspect_get_major_version
* inspect_get_minor_version
* inspect_get_arch
* inspect_get_hostname
* inspect_get_windows_systemroot
* inspect_get_windows_software_hive
* inspect_get_windows_system_hive
* inspect_get_windows_current_control_set
* inspect_get_drive_mappings
* inspect_is_live
* inspect_is_netinst
* inspect_is_multipart

The following inspection APIs have NOT been reimplemented in this commit:

* inspect_list_applications [deprecated]
* inspect_list_applications2
* inspect_get_icon

This also embeds the ocaml-augeas library (upstream here:
http://git.annexia.org/?p=ocaml-augeas.git;a=summary), but it's
identical to the upstream version and should remain so.
