Andrew Cooper 6b3da2ba3b libxl/save&restore&convert: Switch to new EMULATOR_XENSTORE_DATA records 
Read and write "toolstack" information using the new
EMULATOR_XENSTORE_DATA record, and have the conversion script take care
of the old format.

The entire libxc and libxl migration v2 streams are now bitness-neutral
in their records.

Andrew Cooper 47801b0451 docs/libxl: Re-specify XENSTORE_DATA as EMULATOR_XENSTORE_DATA 
The legacy "toolstack" record as implemented in libxl turns out not to
be 32/64bit safe.  As migration v2 has not shipped yet, take this
opportunity to adjust the specification and fix the incompatibility.

Libxl shall loose all knowledge of the old "toolstack" blob and use this
EMULATOR_XENSTORE_DATA record instead.  Compatibility shall be handled
by the legacy conversion script.

Andrew Cooper 74a7c7a928 tools/python: Conversion utility for legacy migration streams 
This utility will take a legacy stream as in input, and produce a v2
stream as an output.  It is exec()'d by libxl to provide backwards
compatibility.
