block: BLOCK_IO_ERROR QMP event
This commit introduces the bdrv_mon_event() function, which
should be called by block subsystems (eg. IDE) when a I/O
error occurs, so that an QMP event is emitted.
The following information is currently provided in the event:
- device name
- operation (ie. "read" or "write")
- action taken (eg. "stop")
Event example:
{ "event": "BLOCK_IO_ERROR",
"data": { "device": "ide0-hd1",
"operation": "write",
"action": "stop" },
"timestamp": { "seconds":
1265044230, "microseconds": 450486 } }

Documentation: Add build support for documentation in pdf format
Makefile already supported dvi, html and info formats,
but pdf was missing.
pdf is especially convenient for printing and for
documentation reviews. I hope it will help to
improve qemu's documentation.
Make now supports the new target 'pdf' which will
create qemu-doc.pdf and qemu-tech.pdf. It is also
possible to build both files individually.
texi2pdf and texi2dvi are rather noisy, so normally
some less important warnings are suppressed.
When make is called with V=1 (verbose mode),
warnings are not suppressed.

kvm: Flush coalesced MMIO buffer periodly
The default action of coalesced MMIO is, cache the writing in buffer, until:
1. The buffer is full.
2. Or the exit to QEmu due to other reasons.
But this would result in a very late writing in some condition.
1. The each time write to MMIO content is small.
2. The writing interval is big.
3. No need for input or accessing other devices frequently.
This issue was observed in a experimental embbed system. The test image
simply print "test" every 1 seconds. The output in QEmu meets expectation,
but the output in KVM is delayed for seconds.
Per Avi's suggestion, I hooked flushing coalesced MMIO buffer in VGA update
handler. By this way, We don't need vcpu explicit exit to QEmu to
handle this issue.
