Use a script to update DEBUG macro invocations to use it as a variadic
macro, supplying format string and its arguments directly, instead of
wrapping them in parens.

This script was used to update the code:

grep -rwl --include '*.[hc]' DEBUG . |
    while read f; do
        mv "$f"{,.orig}
        perl -e \
            'use strict;
             use File::Slurp;
             my $text=read_file(\*STDIN);
             $text=~s#(\bDEBUG\s*\([^(]+)\((.*?)\)\s*\)\s*;#$1$2);#gs;
             print $text;' < "$f.orig" > "$f"
        rm "$f.orig"
    done

To correctly decide if an object is a member of the main sssd domain, a flat name
is needed. However, the information may not be available when the module is
inited so it may be necessary to refresh this data later while processing a
request.

Changes the simple access provider's interface to be asynchronous. When
the simple access provider encounters a group that has gid, but no
meaningful name, it attempts to resolve the name using the
be_file_account_request function.

Some providers (like the AD provider) might perform initgroups
without resolving the group names. In order for the simple access
provider to work correctly, we need to resolve the groups before
performing the access check. In AD provider, the situation is
even more tricky b/c the groups HAVE name, but their name
attribute is set to SID and they are set as non-POSIX

Call it everywhere instead of directly dereferencing be_req->fn
This is in preparation of making be_req opaque.

Need to split out the function or new additions to the handler funtion will not
allow simple access tests to compile anymore.
