This patch adds a bdrv_flush_all() function.  It's necessary to ensure that all
IO operations have been flushed to disk before completely a live migration.

N.B. we don't actually use this now.  We really should flush the block drivers
using an live savevm callback to avoid unnecessary guest down time.

Live migration happens in the background, but it is useful to make the monitor
command appear as if it's blocking.  This allows a management tool to
immediately know when the live migration has completed without having to poll
the migration status.

This patch allows the monitor to be suspended from a monitor callback which
will prevent new monitor commands from being executed.

Forced the constant's width to long long so that it doesn't overflow,
problem spotted by C. W. Betts.

This adds support for CPUID_EXT_SSE41, CPUID_EXT_SSE42, CPUID_EXT_POPCNT
extensions.  Most instructions haven't been tested yet.

pfl->wcycle was set to 1 when the erase confirm command was set, which
lead to the next command being misinterpreted by Qemu:

pflash_write: Unimplemented flash cmd sequence (offset 00000000,
wcycle 0x1 cmd 0x20 value 0x70)

This patch fixes this issue by resetting pfl->wcycle to 0 on erase
confirm so that the next command is considered as a new one.

Use rldimi instead of rldicr/or pair, saves us one instruction.

load_seg_vm calls cpu_x86_load_seg_cache which updates hflags of
current env, real hardware doesn't do this, nor the code that handles
real mode lret/lcall/ljmp.

This unbreaks "unreal mode" and makes QEMU the first emulator being
able to run Project Angel demo by IMPACT Studios. (Not that there are
many physical machines out there capable of doing the same)
