1st: we were synchonizing the dirty bitmap before calling
memory_global_dirty_log_start().

2nd: We are marking all pages as dirty anywhere, no reason to go
through all the bitmap to "mark" dirty same pages twice.

So, call removed.

Exit loop if we have been there too long

Checking each 64 pages is a random magic number as good as any other.
We don't want to test too many times, but on the other hand,
qemu_get_clock_ns() is not so expensive either. We want to be sure
that we spent less than 50ms (half of buffered_file timer), if we
spent more than 100ms, all the accounting got wrong.

arch_init: Fix AltiVec build on Darwin/ppc

Commit f29a56147b66845914d0a645bf9b4c5bb9a6af57 (implement
-no-user-config command-line option (v3)) introduced uses of bool
in arch_init.c. Shortly before that usage is support code for
AltiVec (conditional to __ALTIVEC__).

GCC's altivec.h may in a !__APPLE_ALTIVEC__ code path redefine bool,
leading to type mismatches. altivec.h recommends to #undef for C++
compatibility, but doing so in C leads to bool remaining undefined.

Fix by redefining bool to _Bool as mandated for stdbool.h by POSIX.

Purge migration of (almost) everything to do with monitors

The Monitor object is passed back and forth within the migration/savevm
code so that it can print errors and progress to the user.

However, that approach assumes a HMP monitor, being completely invalid
in QMP.

This commit drops almost every single usage of the Monitor object, all
monitor_printf() calls have been converted into DPRINTF() ones.

There are a few remaining Monitor objects, those are going to be dropped
by the next commit.
