'-cpu host' makes the CPU look like the host CPU. This is useful
because it means the appliance can use all the host CPU's features,
eg. for fast checksumming or MD XORing.
'kvmclock' is the paravirtualized clock for qemu/KVM. It's much more
stable than relying on tsc or a virtualized device such as HPET, and
clock instability is one of the problems we have encountered when
running libguestfs on a heavily loaded machine, especially in a nested VM.
Note that we require qemu >= 1.2 (and have for a while) which has long
supported both of these options.
This large, but mainly mechanical commit, renames "attach method"
everywhere to "backend".
Backwards compatibility of the API (guestfs_{set,get}_attach_method)
and environment (LIBGUESTFS_ATTACH_METHOD) is maintained, but in new
code use guestfs_{set,get}_backend and LIBGUESTFS_BACKEND instead.
The default backend (launching qemu directly) is now called 'direct'
instead of 'appliance', although you can still use 'appliance' as a
synonym.
The cleanup of package managers cache is already implemented
by sprep_operation_package_manager_cache.ml, so remove this
TODO item.

Let tests/bigdirs/test-big-dirs.pl uses mke2fs to create small
inode ratio files.

RWMJ:
- Fix invocation of mke2fs with optional arguments.
- Run the test to check it works.
I tested this by comparing the output of virt-inspector over Windows
guests before and after the change, which was identical:

Note that we keep the old daemon calls, but rename them as
"internal_write" and "internal_write_append". This lets us implement
the new library-side calls more efficiently in the common case when
the uploaded content is smaller than the message buffer. In most
cases the new calls won't end up using a temporary file.
remove the local machine ID, leave it empty, let it be generated
during next booting.
