[SCM] Samba Shared Repository - branch master updated

The branch, master has been updated
       via  8ee30be Add in the threaded async open engine.
      from  d81e206 Move set_thread_credentials_permanently() to set_thread_credentials() as we need to
keep the saved set uid/gid otherwise there is an interaction with open[at]() and NO_ATIME returning
EPERM. As this is meant for threaded code inside the process we don't need to do an irreverisble change anyway.

commit 8ee30be431246863a0ddb2f942b7b6fe51788d6d

    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.
