We need to evaluate $libexecdir in configure, otherwise we literally end
up with "${prefix}/libexec" instead of the absolute path as
CONFIG_QEMU_HELPERDIR.

Update the -help output and documentation so that it recommends
'help' rather than '?' for the various "list valid values for this
option" cases. '?' is deprecated (as it can fail confusingly if
not quoted), so it's better to steer users towards 'help'. ('?'
still works, for backwards compatibility.)
This is the -help option part of the change otherwise done in
commit c8057f9, since we are now past release 1.2 and free to
change our help text without worrying about breaking libvirt.

Commit 4be403c accidentally defined the target_phys_addr_t type when
building user-mode emulators. Since the type doesn't really make
any sense except for system emulators, avoid defining it when building
in user mode.

If TIGHT_PNG is not enabled by the --enable-vnc-png configure flag
then do not report to the client that it is supported.
Also, since TIGHT_PNG is the same as the TIGHT encoding but with the
filter/copy replaced with PNG data, adding it to the supported
encodings list when it is disabled will cause the TIGHT encoding to be
used even though the client requested TIGHT_PNG.

Instructions that both use the RRX second operand and update CS were
incorrect, as the Carry flag was updated too early. An example of such an
instruction would be:
ands r12,r13,RRX
Ands, because of the "s" flag will update the carry flag. But the RRX second
operand rotates through the C flag which should happen before the update.
Fixed the ordering of the two, the old carry is read by "r13,RRX" before being
updated.

This patch creates a migration bitmap, which is periodically kept in
sync with the qemu bitmap. A separate copy of the dirty bitmap for the
migration limits the amount of concurrent access to the qemu bitmap
from iothread and migration thread (which requires taking the big
lock).
We use the qemu bitmap type. We have to "undo" the dirty_pages
counting optimization on the general dirty bitmap and do the counting
optimization with the migration local bitmap.
