We pass be_path to tapdisk_destroy but we've already deleted it so it
fails to read tapdisk-params. However it appears that we need to
destroy the tap device after tearing down xenstore, to avoid the leak
reported by Greg Wettstein in
<201207312141.q6VLfJje012656@wind.enjellic.com>.
So read the tapdisk-params in the cleanup transaction, before the
remove, and pass that down to destroy_tapdisk instead. tapdisk-params
may of course be NULL if the device isn't a tap device.
There is no need to tear down the tap device from
libxl__initiate_device_remove since this ultimately calls
libxl__device_destroy.
Propagate and log errors from libxl__device_destroy_tapdisk.

Move a lot of
#include <stdfoo.h>
from individual files into libxl_internal.h. This helps avoid
portability mistakes where necessary system headers are omitted from
individual files, and is also of course a convenience when developing.
Also add
#include "libxl_osdeps.h" /* must come before any other headers */
to the top of most libxl*.c files, so that anyone who adds any headers
before libxl_internal.h will put the in the right place.

libxl_internal.h now #includes libxl.h and various system headers.
This
1. makes the order of header inclusion more predictable
2. explicitly allows libxl_internal.h to use objects defined in libxl.h
3. removes the need for individual files to include these headers
Also
- remove some unnecessary #includes of libxl_utils.h,
flexarray.h, etc. in some libxl*.c files,
- include libxl_osdeps.h at the top of libxl_internal.h
- add missing includes of libxl_osdeps.h to a couple of files
- change libxl.h to libxl_internal.h in a couple of files

Several places which were previsously indented using hard tabs are now
incorrectly indented. Fix them up.

A step on the path to sharing this code with the tail-end of the
DISK_BACKEND_TAP case.
I made the result of libxl__blktap_devpath non-const to achieve
this. The existing caller calls libxl__strdup on the result but since
the function is an internal one and the result is already garbage
collected I think this is unnecessary and we can just use the
non-const result directly.

Currently we pile all the backend and format information pertaining to
disk option in a single enum. This check-in separates the two and
uses two enums, one for disk format and another for disk backend.
This helps clearly differentiate between disk format and backend
within the implementation and also helps cleanup the code in this area
in preparation for the impending parser revamping to be done post 4.1.
Along with separating format and backend, this check-in also removes
unwanted types and renames variables in the disk interface and fixes
the code affected by the interface changes.
In specific, here are the disk interface changes made - In
libxl_device_disk structure physpath was renamed to pdev_path,
virtpath was renamed to vdev, phystype was removed and replaced with
backend and format enums. Also previously a single enum
libxl_disk_phystype held the values for qcow, qcow2, vhd, aio, file,
phy, empty and that got refactored into two enums, libxl_disk_format
to hold unknown, qcow, qcow2, vhd, raw, empty and libxl_disk_backend
to hold unknown, phy, tap and qdisk.

It's not clear that the namespace rules described in libxl.h are
intended to apply to internal types but I don't see why not.
