More specifically:
1. replaces xenctl_cpumap with xenctl_bitmap
2. provides bitmap_to_xenctl_bitmap and the reverse;
3. re-implement cpumask_to_xenctl_bitmap with
bitmap_to_xenctl_bitmap and the reverse;
Other than #3, no functional changes. Interface only slightly
afected.
This is in preparation of introducing NUMA node-affinity maps.

Cpumap types in tools (libxc and libxl) are changed to be based on bytes like
in the interface to the hypervisor.
To make handling easier the size of used cpumaps is always based on the
number of physical cpus supported by the hypervisor. This eliminates the need
to keep track of the cpumap size in external interfaces.
In libxl a macro for cycling through a cpumap is added (libxl_for_each_cpu).
Interfaces changed:
libxl_set_vcpuaffinity()
libxl_cpumap_alloc()
xc_vcpu_setaffinity()
xc_vcpu_getaffinity()
xc_cpupool_freeinfo()

Rename xc_set_xen_guest_handle to set_xen_guest_handle[0] and remove now
unused functions:
- xc_memalign
- lock_pages
- unlock_pages
- hcall_buf_prep
- hcall_buf_release

To be able to support arbitrary numbers of physical cpus it was necessary to
include the size of cpumaps in the xc-interfaces for cpu pools.
These were:
definition of xc_cpupoolinfo_t
xc_cpupool_getinfo()
xc_cpupool_freeinfo()
xc_cpupool_getinfo() and xc_cpupool_freeinfo() are changed to allocate the
needed buffer and return it.

Not actually used here but useful to confirm that a handle is passed
down to each location where it will be required once we switch to
hypercall buffers.

tools/libxc, tools/libelf: Relicense under LGPL v2.1
Relicense these two libraries under LGPL v2.1 only except where
individual files already included the "or later" provision.
Copyright holders have been contacted by Stephen Spector and have all
agreed this change.
Removed tools/libxc/ia64/aclinux.h since it appeared to be
unused. There is a separate, more up to date, copy in
xen/include/acpi/platform/aclinux.h which does appear to be used.
Clarify the license of MiniOS privcmd.h under the same terms as other
tools/include/xen-sys headers.

This patch eliminate the global variables in libxenctrl (used for
logging and error reporting).
Instead the information which was in the global variables is now in a
new xc_interface* opaque structure, which xc_interface open returns
instead of the raw file descriptor; furthermore, logging is done via
xentoollog.
There are three new parameters to xc_interface_open to control the
logging, but existing callers can just pass "0" for all three to get
the old behaviour.
All libxc callers have been adjusted accordingly.
Also update QEMU_TAG for corresponding qemu change.
