Drop the assumption that we're using the main AioContext. Convert qemu_bh_new() to aio_bh_new() so we use the BlockDriverState's AioContext. The .bdrv_detach_aio_context() and .bdrv_attach_aio_context() interfaces are not needed since no fd handlers, timers, or BHs stay registered when requests have been drained.

Make bdrv_open() take a pointer to a BDS pointer, similarly to bdrv_file_open(). If a pointer to a NULL pointer is given, bdrv_open() will create a new BDS with an empty name; if the BDS pointer is not NULL, that existing BDS will be reused (in the same way as bdrv_open() already did).

error_is_set(&var) is the same as var != NULL, but it takes whole-program analysis to figure that out. Unnecessarily hard for optimizers, static checkers, and human readers. Dumb it down to obvious. Gets rid of several dozen Coverity false positives. Note that the obvious form is already used in many places.

If the filename is not prefixed by "blkdebug:" in blkdebug_parse_filename(), the blkdebug driver was not selected through that protocol prefix, but by an explicit command line option (file.driver=blkdebug or something similar). Contrary to the current reaction, this is not a problem at all; we just need to store the filename (in the x-image option) and can go on; the user just has to manually specify the config option.

This allows more systematic AIO testing. The patch adds three new operations to blkdebug: * Setting a "breakpoint" on a blkdebug event. The next request that triggers this breakpoint is suspended and is tagged with a name. The breakpoint is removed after a request has triggered it. * A suspended request (identified by it's tag) can be resumed * It's possible to check whether a suspended request with a given tag exists. This can be used for waiting for an event. Ideally, we would instead tag requests right when they are created and set breakpoints for individual requests. However, at this point the block layer doesn't allow this easily, and breakpoints that trigger for any request already allow a lot of useful testing. Signed-off-by: NKevin Wolf <kwolf@redhat.com>

Currently it is impossible to write a blkdebug script that ping-pongs between two states, because the second set-state rule will use the state that is set in the first. If you have [set-state] event = "..." state = "1" new_state = "2" [set-state] event = "..." state = "2" new_state = "1" for example the state will remain locked at 1. This can be fixed by first processing all rules, and then setting the state.
