Instead, put the CURLAIOCB on a wait list and yield; curl_clean_state will
wake the corresponding coroutine.

Because of CURL's callback-based structure, we cannot easily convert
everything to CoMutex/CoQueue; keeping the QemuMutex is simpler.  However,
CoQueue is a simple wrapper around a linked list, so we can easily
use QSIMPLEQ and open-code a CoQueue, protected by the BDRVCURLState
QemuMutex instead of a CoMutex.

This is pretty simple.  The bottom half goes away because, unlike
bdrv_aio_readv, coroutine-based read can return immediately without
yielding.  However, for simplicity I kept the former bottom half
handler in a separate function.

This is in preparation for the conversion from bdrv_aio_readv to
bdrv_co_preadv, and it also requires changing some of the size_t values
to uint64_t.  This was broken before for disks > 2TB, but now it would
break at 4GB.

If curl_easy_init fails, a CURLState is left with s->in_use = 1.  Split
curl_init_state in two, so that we can distinguish the two failures and
call curl_clean_state if needed.

While at it, simplify curl_find_state, removing a dummy loop.  The
aio_poll loop is moved to the sole caller that needs it.

The curl driver has a ugly hack where, if it cannot find an empty CURLState,
it just uses aio_poll to wait for one to be empty.  This is probably
buggy when used together with dataplane, and the simplest way to fix it
is to use coroutines instead.

A more immediate effect of the bug however is that it can cause a
recursive call to curl_readv_bh_cb and recursively taking the
BDRVCURLState mutex.  This causes a deadlock.

The fix is to unlock the mutex around aio_poll, but for cleanliness we
should also take the mutex around all calls to curl_init_state, even if
reaching the unlock/lock pair is impossible.  The same is true for
curl_clean_state.

When using the mapped-file security mode, we shouldn't let the client mess
with the metadata. The current code already tries to hide the metadata dir
from the client by skipping it in local_readdir(). But the client can still
access or modify it through several other operations. This can be used to
escalate privileges in the guest.

Affected backend operations are:
- local_mknod()
- local_mkdir()
- local_open2()
- local_symlink()
- local_link()
- local_unlinkat()
- local_renameat()
- local_rename()
- local_name_to_path()

Other operations are safe because they are only passed a fid path, which
is computed internally in local_name_to_path().

This patch converts all the functions listed above to fail and return
EINVAL when being passed the name of the metadata dir. This may look
like a poor choice for errno, but there's no such thing as an illegal
path name on Linux and I could not think of anything better.

This fixes CVE-2017-7493.

ppc patch queue for 2017-05-11

This pull request supersedes the one from yesterday (20170510), fixing
an important style bug in one patch, and adding an extra couple of
simple patches.

Highlights of this set:
  * Some fixes for POWER9
  * TCG support for POWER9 radix MMU
  * VGA rom for Mac machine types
  * Fixes for the XICS interrupt controller
  * MTTCG support for ppc targets

As suggested by Paolo, I've tried to add the Docker tests to my
standard pre-pull-request tests.  I haven't wholly suceeded; this has
been tested with some of the Docker images, but others I haven't
managed due to problems that as best I can tell are not due to
problems in this patch series.  I'll continue working on this for
future pull requests.  Specifically, 'travis', 'fedora', and 'centos6'
seem to work.  'min-glib' jammed while gtesting moxie, which seems
very unlikely to be caused by this series.  'ubuntu', 'debian' and
'debian-bootstrap' hit build errors almost immediately that look like
problems with the container configuration, and 'debian-*-cross' hit
build errors later on which also look like missing dependencies from
the container.

DELAY_SLOT_CLEARME has not impact on the code generation: in both case
ctx->envflags is cleared, either by clearing all the flags, or by
setting it to 0. This is left-over from pre-TCG era.

There is a confusion (and not only in the SH4 target) between tb->flags,
env->flags and ctx->flags. To avoid it, split ctx->flags into
ctx->tbflags and ctx->envflags. ctx->tbflags stays unchanged during the
whole TB translation, while ctx->envflags evolves and is kept in sync
with env->flags using TCG instructions. ctx->envflags now only contains
the part that of env->flags that is contained in the TB state, i.e. the
DELAY_SLOT* flags.

The SIGNAL PROCESSOR helper returns its value through the CC register.
set_cc_static should be called just after the helper.
