Currently qemu has a bug: When maxvcpus > 64, qemu will get wrong
vcpu bitmap (s->cpus_sts[i]) since it only get bitmap from a long
variable.
This patch, cooperate with another qemu patch, is to fix this bug.
This patch transfer a vcpu_avail string in a hex string format, so
that at qemu side it's more easier to get vcpu bitmap from hex string,
especially when many vcpus, like more than 64.
(Also update QEMU_TAG for matching qemu-side update)

This provides a replacement config file parser for "xl" based on bison
and flex.
Benefits:
* proper error reporting with line numbers
* parser can understand nearly all "xm" configuration files directly
(doesn't understand Python code but should do everything else)
* parser also understands the ;-infested "xl" style files
* removes the dependency on libconfig
* better checking for certain kinds of mistakes
* eliminates the strange "massage file and try again" code
This is intended to support all config files currently supported by
"xl" and almost all files supported by "xm". (NB that whether a
feature works depends on the implementation of that feature in
xl/libxl of course.)
This patch also introduces a new library "libxlutil" which is mainly
for the benefit of "xl". Users of libxl do not need to use libxlutil,
but they can do so if they want to parse "xl" files without being
"xl".

Reduce size of Xen-qemu shared ioreq structure to 32 bytes. This
has two advantages:
1. We can support up to 128 VCPUs with a single shared page
2. If/when we want to go beyond 128 VCPUs, a whole number of ioreq_t
structures will pack into a single shared page, so a multi-page
array will have no ioreq_t straddling a page boundary
Also, while modifying qemu, replace a 32-entry vcpu-indexed array
with a dynamically-allocated array.

This patch adds securty checks for pci passthrough related hypercalls
to enforce that the current domain owns the resources that it is about
to remap. It also adds a call to xc_assign_device to xend and removes
the PRIVILEGED_STUBDOMS flags.

xenbits supports the git protocol now, which is much faster (and
produces less noise in the build log too).
