Fix a couple of minor bugs in xen-access test program:
* Fix -m option handling.
* Fix a segfault that was occurring during program exit.

Several places include it in CFLAGS even though it is never defined. A
few others use it as nothing more than a gathering point for
CFLAGS. Get rid of it.

Otherwise make can search the path relative to certain standard paths
such as /usr/include (e.g., the line '-include $(XEN_ROOT)/.config' in
Config.mk suffers from this).

A software MCE injection tool, which is based on Xen MCE injection
mechanism. It fake MCE error and inject this error to a assigned
Domain Physical Address. Makefile make sure the tool can be built on
Xen. A README explain the usage for this tool.

and PV/ramdisk
Add support for 'file:' and 'data:' URI schemes for the parameters
'PV/kernel' and 'PV/ramdisk' in the VM.create() call. The 'data:'
scheme handling enables using a file which is stored inside the
management system (from where the XenAPI call is send) as kernel or
ramdisk.
Notes:
o all included: a detailed description can be found in the xenapi
documentation
o bumped up the version of the API document to 1.0.8 (because of
(minimal) interface extension)
o Future enhancements (like http:, ftp: schemes) fit seamlessly into
the current design / classes
o Unittest cases and xm-test case included

Defer fail_if()-s as much as possible (in favor of possibly generating
exceptions), and avoid generating exceptions when not strictly
necessary.
Avoid fail_if()-s for simple return code checks (making the code that
used them consistent with other, longer existing code).
Eliminate redundant generate_exception_if()-s checking lock_prefix
(which is already covered by the general check prior to decoding
operands).
Also fix the testing code to add PROT_EXEC for the mapping that is
intended to have instruction executed from.

This can be used to perform correct access checks, provide appropriate
error codes when injecting faults, and to implement an
instruction-stream prefetch cache (which is included here for HVM PTE

- No distinction between 'special' and 'normal' memory accesses.
- No reliance on caller-supplied %cr2 value
- Memory operations include segment identifier to allow callers
to support non-zero-based segments
TODO:
1. HVM emulations should take into account segment base, limit, and
attributes.
2. We ought to obey stack-size attribute on PUSH/POP instructions.
Could extend the mode input field, or could add an extra call-out
hook, or perhaps we don't care at all...
