New APIs for guest inspection.

This commit converts (some of) the Perl inspection code to C and
makes it available through core APIs.  The new APIs are:

inspect-os        - Does the inspection, returns list of OSes
inspect-get-*     - Get results of the inspection

where '*' is one of:

  type            - 'windows' or 'linux'
  distro          - Linux distro
  arch            - architecture
  product-name    - long product name string
  major-version
  minor-version   - major.minor version of OS
  mountpoints     - get a list of the mountpoints
  filesystems     - get all filesystems associated with the OS

This works for all existing supported Linux and Windows OSes.

Revert "add_drive_ro adds readonly=on option if available." (RHBZ#617200).

Adding the readonly=on option is not so clever.  This causes
qemu to present the disk as read-only to the guest.  (The
expected behaviour of snapshots=on,readonly=on was that it
would open the disk O_RDONLY but present a writable disk to
the guest).

Since the guest sees a read-only disk, we are unable to do any
recovery if a filesystem on the disk is inconsistent.  This basically
prevents most accesses to live disk images.

What we really want is a qemu option which presents a writable
disk to the guest, but only opens the disk on the host side with
O_RDONLY, to alleviate the udev bug RHBZ#571714.

  free (filename);
  if (r == -1)
    ocaml_guestfs_raise_error (g, "add_drive_ro");

Also included is a regression test.

perl: Add explicit close() method (RHBZ#602592).

This add an optional explicit $g->close method which may be
used to force the handle to be closed immediately.  Note the
provisos about this method in the manual page entry.  Callers
should *not* normally use this method.

The implementation of the handle also changes.  Before, the
handle was a blessed reference to an integer (the integer
being the pointer to the C guestfs_h handle).  Now we change
this to a hashref containing currently the following field:

  _g => pointer to C guestfs_h handle (as an integer)

If this field is not present, it means that the handle has been
explicitly closed.  This avoids double-freeing the handle.

The user may add their own fields to this hash in order to store
per-handle data.  However any fields whose names begin with
an underscore are reserved for use by the Perl bindings.

This commit also adds a regression test.

This commit also changes the existing warning when you call
a method without a Sys::Guestfs handle as the first parameter,

We could fix this so that the human-readable numbers get written
into the CSV file.  However would probably be wrong for most uses
of the CSV format (databases and spreadsheets) since they would not

misinterpret, eg. thinking that "1M" and "1G" are both 1.

file: Restrict to regular files (RHBZ#582484).

The file call can hang if called on char devices (because we are
using the file -s option).

This is hard to solve cleanly without adding another file API.

However this restricts file to regular files, unless called explicitly
with a /dev/ path.  For non-regular files, it will now return a
string like "directory".

There is a small semantic change for symbolic links.  Previously
it would not have worked at all on absolute links (or rather, the
results would have been undefined).  It would have treated relative
symlinks to regular files as the regular file itself.  Now it will
return the string "symbolic link" in both cases.

This commit also makes the API safe when called on untrusted
filesystems.  Previously a filesystem might have been set up so
that (eg) /etc/redhat-release was a char device, which would have
caused virt-inspector and virt-v2v to hang.  Now it will not hang.
