According to linux kernel commit <89c1e79eb30> ("linux/bitmap.h: improve
BITMAP_{LAST,FIRST}_WORD_MASK"), these two macro could be improved.
This patch takes this change and also move them all in header file.

The shipping default setting for the Freescale M5208EVB board is to run
the CPU at 166.67MHz. The current qemu emulation code for this board is
defaulting to 66MHz. This results in time appearing to run way to slowly.
So a "sleep 5" in a standard ColdFire Linux build takes almost 15
seconds in real time to actually complete.
Change the hard coded default to match the default hardware setting.

dmg.o was moved to block-obj-m in 5505e8b76 to become a separate module,
so that its reference to libbz2, since 6b383c08c, doesn't add an extra
library to the main executable.
Until recently, commit 06e60f70a (blockdev: Add dynamic module loading
for block drivers) moved it back to block-obj-y to simplify the design
of dynamic loading of block modules. But we don't want to lose the
feature of less library dependency on the main executable.
The solution here is to move only the bz2 related code to a separate
DSO file, and load it when dmg_open is called.
dmg_probe doesn't depend on bz2 support to work, and is the only code in
this file which can run before dmg_open.
While we are at it, fix the unhelpful cast of last argument passed to
dmg_uncompress_bz2.

The event currently only contains the BlockBackend name. However, with

which device caused the event.
Event generation has to be moved from bdrv_eject() to the BlockBackend
because the BDS doesn't know the attached device, but that's easy
because blk_eject() is the only user of it.

Recently we moved a few options from QemuOptsLists in blockdev.c to
bdrv_runtime_opts in block.c in order to make them accissble using
blockdev-add. However, this has the side effect that these options are
missing from query-command-line-options now, and libvirt consequently
disables the corresponding feature.
This problem was reported as a regression for the 'discard' option,
introduced in commit 818584a4. However, it is more general than that.
Fix it by adding bdrv_runtime_opts to the list of QemuOptsLists that are
returned in query-command-line-options. For the future, libvirt is
advised to use QMP schema introspection for block device options.

qemu_bh_delete is already clearing bh->scheduled at the same time
as it's setting bh->deleted. Since it's not using any memory
barriers, there is no synchronization going on for bh->deleted,
and this makes the bh->deleted checks superfluous in aio_compute_timeout,
aio_bh_poll and aio_ctx_check.
Just remove them, and put the (bh->scheduled && bh->deleted) combo
to work in a new function aio_bh_schedule_oneshot. The new function
removes the need to save the QEMUBH pointer between the creation
and the execution of the bottom half.
