e454681276 Linux-specific optimization in aio_open code. 
Use initial_allocation_size to allocate on disk if sent. Ignore
failures (upper level will cope).

cb405947ca Add an optimization to pthread aio writes to also do fsync if requested. 
Should help by ensuring complete writes done in sub-thread, not in
the main thread.

8ee30be431 Add in the threaded async open engine. 
Fixes all issues raised originally. This code
will only do threaded opens with thread-specific
credentials (Linux for now) and changes credentials
before doing the call. Also only fires on O_CREAT|O_EXCL
so will only create new files, never open old ones
async.

Volker, this is isolated enough that it shouldn't
prevent you from refactoring it into a new module
when the aio pread/pwrite code is moved into the
default aio path.

e02a788f60 Simplify the logic around doing an immediate event reschedule. 
We don't need to do a talloc here, we already have a long-lived
pointer we can pass in as the private data.
