eff3609 moved the async signal handler initialization to later in the process
to enable aio_fork and aio_pthread on platforms without realtime signals. This
commit broke the use of the native aio interface. aio_pending_size is
initialized to 0, so aio.c will not allow async i/0 at all if modules do not
set that variable correctly. Initialize to 100 right from the start.

With this change, the define to check for AIO is HAVE_AIO, consistant
with other subsystems.
It is now also on by default in the autoconf build, as it has been for waf.

This way we can't end up with a mismatch between outstanding events and the counter.
We may still have problems with canceling and not correctly freeing the aio
struct, but at least the counter won't get out of sync anymore.
On platforms that don't have an RT signal space, signal initialization
fails. aio_fork and aio_pthread don't need the signal, so this would
block them from running as well.
Now that we always require a 64 bit off_t, we no longer need SMB_OFF_T.

call out of smbd_aio_complete_aio_ex() and into the caller.

This has been a wrapper around server_event_context() for some time
now, and removing this from dummmysmbd.c assists with library
dependencies.

Change smb2_read code to allocate return DATA_BLOB just before the read.
Preparing for SMB2 sendfile change which will not need to allocate
return buffer.

In the includes we define SIGRTMIN to 32 if it's not defined already. This
value could be fairly low and it's better to use NSIG(number of defined
signals) as the lower mark for the available signals.
We have similar defenition in the source3/smbd/aio.c, which can be safely
removed, as it comes from includes.h then.
With regards,
Timur Bakeyev.

The aio_fork module does not need this, as it does not communicate via signals
but with pipes. Watching a strace log with those become_root() calls in aio.c
is absolutely awful, and it does affect performance.
