xen-block: implement BlockDevOps->drained_begin()
Detach event channels during drained sections to stop I/O submission from the ring. xen-block is no longer reliant on aio_disable_external() after this patch. This will allow us to remove the aio_disable_external() API once all other code that relies on it is converted.
Extend xen_device_set_event_channel_context() to allow ctx=NULL. The event channel still exists but the event loop does not monitor the file descriptor. Event channel processing can resume by calling xen_device_set_event_channel_context() with a non-NULL ctx.
Factor out xen_device_set_event_channel_context() calls in hw/block/dataplane/xen-block.c into attach/detach helper functions. Incidentally, these don't require the AioContext lock because aio_set_fd_handler() is thread-safe.
It's safer to register BlockDevOps after the dataplane instance has been created. The BlockDevOps .drained_begin/end() callbacks depend on the dataplane instance, so move the blk_set_dev_ops() call after xen_block_dataplane_create().

xen-block: support feature-large-sector-size
A recent Xen commit [1] clarified the semantics of sector based quantities used in the blkif protocol such that it is now safe to create a xen-block device with a logical_block_size != 512, as long as the device only connects to a frontend advertizing 'feature-large-block-size'.
This patch modifies xen-block accordingly. It also uses a stack variable for the BlockBackend in xen_block_realize() to avoid repeated dereferencing of the BlockConf pointer, and changes the parameters of xen_block_dataplane_create() so that the BlockBackend pointer and sector size are passed expicitly rather than implicitly via the BlockConf.
These modifications have been tested against a recent Windows PV XENVBD driver [2] using a xen-disk device with a 4kB logical block size.

xen: add header and build dataplane/xen-block.c
This patch adds the transformations necessary to get dataplane/xen-block.c to build against the new XenBus/XenDevice framework. MAINTAINERS is also updated due to the introduction of dataplane/xen-block.h.
NOTE: Existing data structure names are retained for the moment. These will be modified by subsequent patches. A typedef for XenBlockDataPlane has been added to the header (based on the old struct XenBlkDev name for the moment) so that the old names don't need to leak out of the dataplane code.
