XendDomain.py:
Remove domain_db cache -- it's tedious to maintain and has zero use since
it gets flushed to the XendDB immediately on every update and it's never
consulted except for maintaining it.

Little blkif interface and xend fixes to make parallax work again.
Also minor debug printing fix to blktap.

Rename memparse() to parse_size_and_unit(). A more general-purpose
name, and avoids unecessary clash with Linux function name.

Ensure correct alignment of CPU0 stack -- it must be aligned on a
2^STACK_ORDER page boundary. This requirement is now also checked
at run-time, and a clear fatal error given if it is not satisfied.
This bug affected both x86/32 and x86/64.

Do not set jumbo MTU on the fake netfront/back loopback device. It
causes packet loss at the Ethernet bridge (since bridges do not
fragment IP packets).

Add l?e_create_page() macros. map_pages_to_xen() now takes a pfn range
rather than a byte range. Fix x86/64 RAM mapping to discard partial
frames.

Clean up, fix, and rationalise RAM mapping in Xen.
First, x86/64 must take care to map only registered RAM areas and not
adjacent I/O holes -- otherwise a cpu may cache I/O space and cause
coherency conflicts on the memory bus.
Second, map_pages() and the memguard mechanisms are no longer sub-arch
specific (moved to arch/x86/mm.c:map_pages_to_xen()).

Cleaner GDT interface. Xen now reserves the last 2 pages of a full-size
(16 page) GDT. A guest can register a GDT with up to 7k entries. Xen
automatically makes the GDT up to max size with empty page mappings,
and turns page faults in that area to #GP(selector).

Fallback behaviour of the network startup script is now same as it
always was: IP addresses of eth0 are transferred to the bridge device
but not deleted from eth0. This is needed for the 2.0-series tools,
which by default look only at eth0 to determine IP parameters for domU.
