kaf24@firebug.cl.cam.ac.uk 794c430127 The attached patch converts the balloon driver and xend to use 
xenstore instead of control messages.

Note: Because there is no way to set a watch on a non-existent key,
this patch includes a workaround to account for the fact that dom0's
store keys are not initialized by the tools before it boots.

kaf24@firebug.cl.cam.ac.uk 7edf4b7901 This patch adds two macros for construction of the 
frame_and_sectors field in blkif messages, to eliminate the
"magic shifts" in the blkif code.

It also increases the number of bits representing the sector
number within a page, from 3 to 5, to allow page sizes up to
16K (needed for IA64).

Tested to still work on x86.

kaf24@firebug.cl.cam.ac.uk bbb0eb3225 First cut of new time interfaces and synchronisation mechanisms. 
Based on an initial patch from Don Fry at IBM.
Still TODO: 
 1. Testing
 2. NTP synchronisation
 3. Fix wallclock interface a bit
 4. Support for platform timers other than PIT (e.g., HPET, IBM Cyclone)
 5. Scale 64-bit TSC diffs instead of 32-bit, just for sanity
 6. Error-correcting scale factor is still slightly wrong
 6. More testing
