Mirror and migration use dirty bitmaps for their purposes, and since
commit [block: per caller dirty bitmap] they use their own bitmaps, not
the global one. But they use old functions bdrv_set_dirty and
bdrv_reset_dirty, which change all dirty bitmaps.
Named dirty bitmaps series by Fam and Snow are affected: mirroring and
migration will spoil all (not related to this mirroring or migration)
named dirty bitmaps.
This patch fixes this by adding bdrv_set_dirty_bitmap and
bdrv_reset_dirty_bitmap, which change concrete bitmap. Also, to prevent
such mistakes in future, old functions bdrv_(set,reset)_dirty are made
static, for internal block usage.

The splitting of qemu-file and addition of the buffered file landed
at the same time; so now split the buffered file code out.

Now we've got multiple QEMUFile source files, some of them need
access to things that were defined in qemu-file.c, so create
a -internal header for them.

The general feeling is that having migration/migration-blah
is overkill.

The migration code now occupies a fair chunk of the top level .c
files, it seems time to give it it's own directory.
I've not touched:
arch_init.c - that's mostly RAM migration but has a few random other
bits
savevm.c - because it's built target specific
This is purely a code move; no code has changed.
- it fails checkpatch because of old violations, it feels safer
to keep this as purely a move and fix those at some mythical future
date.
The xbzrle and vmstate tests are now only run for softmmu builds
since they require files in the migrate/ directory which is only built
for softmmu.
