If the ensure-alignment code gets triggered, then the
"if (host_start && real_start != current_start)" check will always trigger,
so save 2 syscalls and put that check first.
Note that we can't just switch to using MAP_FIXED for that check, because
then we couldn't differentiate between a failure because "there isn't
enough space" and "there isn't enough space *here*".

Instead of doing
if (check1) {
if (check2) {
success;
}
}
retry;
Do a clearer
if (!check1) {
goto try_again;
}
if (!check2) {
goto try_again;
}
success;
try_again:
retry;
Besides being clearer, this makes it easier to insert more checks that
need to trigger a retry on check failure, or rearrange them, or anything
like that.
Because some indentation is changing, "ignore space change" may be useful
for viewing this patch.

Consider passing a JSON based block driver to "qemu-img commit"
$ qemu-img commit 'json:{"driver":"qcow2","file":{"driver":"gluster",\
"volume":"gv0","path":"sn1.qcow2",
"server":[{"type":\
"tcp","host":"10.73.199.197","port":"24007"}]},}'
Currently it will commit the content and then report an incredibly
useless error message when trying to re-open the committed image:
qemu-img: invalid URI
Usage: file=gluster[+transport]://[host[:port]]volume/path[?socket=...][,file.debug=N][,file.logfile=/path/filename.log]
With this fix we get:
qemu-img: invalid URI json:{"server.0.host": "10.73.199.197",
"driver": "gluster", "path": "luks.qcow2", "server.0.type":
"tcp", "server.0.port": "24007", "volume": "gv0"}
Of course the root cause problem still exists, but now we know
what actually needs fixing.

Some trace backends will compile code based on the declared trace
events. It should not be assumed that the backends can resolve any QEMU
specific typedefs. So trace events should restrict their argument
types to the standard C types and fixed size integer types. Any complex

since nothing will be dereferencing these pointer arguments.

The timestamp argument to a trace event method is documented as follows:
The method can also take a timestamp argument before the trace event
arguments:
def runstate_set(self, timestamp, new_state):
...
Timestamps have the uint64_t type and are in nanoseconds.
In reality methods with a timestamp argument actually receive a tuple
like (123456789,) as the timestamp argument. This is due to a bug in
simpletrace.py.
This patch unpacks the tuple so that methods receive the correct
timestamp argument type.

A persistent build problem we see is where a source file
accidentally omits the #include of log.h. This slips through
local developer testing because if you configure with the
default (log) trace backend trace.h will pull in log.h for you.
Compilation fails only if some other backend is selected.
To make this error cause a compile failure regardless of
the configured trace backend, split out the parts of log.h
that trace.h requires into a new log-for-trace.h header.
Since almost all manual uses of the log.h functions will
use constants or functions which aren't in log-for-trace.h,
this will let us catch missing #include "qemu/log.h" more
consistently.

Nested BDRV_POLL_WHILE() calls can occur. Currently
assert(!wait_->wakeup) fails in AIO_WAIT_WHILE() when this happens.
This patch converts the bool wait_->need_kick flag to an unsigned
wait_->num_waiters counter.
Nesting works correctly because outer AIO_WAIT_WHILE() callers evaluate
the condition again after the inner caller completes (invoking the inner
caller counts as aio_poll() progress).
