CoQueue do not need to remove any element but the head of the list;
processing is always strictly FIFO. Therefore, the simpler singly-linked
QSIMPLEQ can be used instead.

The 'device' field in all BLOCK_JOB_* events and 'block-job-*' command
is no longer the device name, but the ID of the job. This patch
updates the documentation to clarify that.

img_commit() creates a block job without an ID. This is no longer
allowed now that we require it to be unique and well-formed. We were
solving this by having a fallback in block_job_create(), but now that
we extended the API of commit_active_start() we can finally set an
explicit ID and revert that change.

When a new job is created, the job ID is taken from the device name of
the BDS. This patch adds a new 'job_id' parameter to let the caller
provide one instead.
This patch also verifies that the ID is always unique and well-formed.
This causes problems in a couple of places where no ID is being set,
because the BDS does not have a device name.
In the case of test_block_job_start() (from test-blockjob-txn.c) we
can simply use this new 'job_id' parameter to set the missing ID.
In the case of img_commit() (from qemu-img.c) we still don't have the
API to make commit_active_start() set the job ID, so we solve it by
setting a default value. We'll get rid of this as soon as we extend
the API.

find_block_job() looks for a block backend with a specified name,
checks whether it has a block job and acquires its AioContext.
We want to identify jobs by their ID and not by the block backend
they're attached to, so this patch ignores the backends altogether and
gets the job directly. Apart from making the code simpler, this will
allow us to find block jobs once they start having user-specified IDs.
To ensure backward compatibility we keep ERROR_CLASS_DEVICE_NOT_ACTIVE
as the error class if the job doesn't exist. In subsequent patches
we'll also need to keep the device name as the default job ID if the
user doesn't specify a different one.

Currently the way to look for a specific block job is to iterate the
list manually using block_job_next().
Since we want to be able to identify a job primarily by its ID it
makes sense to have a function that does just that.

'stream-start' has a parameter called 'backing-file', which is the
string to be written to bs->backing when the job finishes.
In the stream_start() implementation it is called 'backing_file_str',
but it the prototype in the header file it is called 'base_id'.
This patch fixes it so the name is the same in both cases and is
consistent with other cases (like commit_start()).

This update should preserve git history, and switches git.qemu-project.org
over to be a mirror of the new official git repo hosted at
https://github.com/openbios from a git-svn import of the old coreboot SVN
repository. All prior history from the SVN repository should still be preserved
(i.e. commit hashes are the same for historical commits).
No other source changes are made by this commit since both the old and new
HEADs contain the same source tree (albeit with difference metadata) whilst the
previous git-svn HEAD can be retrieved via the svn-head branch.

Knowing the value of %asi at translation time means that we
can handle the common settings without a function call.
The steady state appears to be %asi == ASI_P, so that sparcv9
code can use offset forms of lda/sta. The %asi register gets
pushed and popped on entry to certain functions, but it rarely
takes on values other than ASI_P or ASI_AIUP. Therefore we're
unlikely to be expanding the set of TBs created.

Doing this instead of saving the raw PS_PRIV and TL. This means
that all nucleus mode TBs (TL > 0) can be shared. This fixes a
bug in that we didn't include HS_PRIV in the TB flags, and so could
produce incorrect TB matches for hypervisor state.
The LSU and DMMU states were unused by the translator. Including
them in TB flags meant unnecessary mismatches from tb_find_fast.

disas/arm-a64.cc is careful to include only the bare minimum that
it needs---qemu/osdep.h and disas/bfd.h. Unfortunately, disas/bfd.h
then includes qemu-common.h, which brings in qemu/option.h and from
there we get the kitchen sink.
This causes problems because for example QEMU's atomic macros
conflict with C++ atomic types. But really all that bfd.h needs
is the fprintf_function typedef, so replace the inclusion of
qemu-common.h with qemu/fprintf-fn.h.

Now that json-streamer tries not to leak tokens on incomplete parse,
the tokens can be freed twice if QEMU destroys the json-streamer
object during the parser->emit call. To fix this, create the new
empty GQueue earlier, so that it is already in place when the old
one is passed to parser->emit.
