This fixes the build without LDAP development headers.

In an overload situation, the winbind helper child process inherits all those
hundreds of fd's which it will never talk to. Close them.
We (Christian Ambach and me) just saw a crash in libkrb5. Christian's analysis
showed that libkrb5 also does select, probably exceeding FD_SETSIZE and
crashing due to that reason. The parent winbind in theory does not do Kerberos
at all, so this should fix that problem.
The crash is interesting because the child process did not really crash.
Somewhere in glibc backtrace() is called, probably due to an assert() or some
explicit consistency check. This then somehow generates a signal probably due
to corrupted memory structures. That signal triggers Samba to again call
backtrace(). This blocks hard on a ptrace_once(). Sorry for the long backtrace
here, but this *is* interesting.
The child process blocking and not really crashing makes the situation worse:
The parent process does not get told the child has crashed and more client
sockets pile up.
This patch is intended to put some relief on this problem by closing the
majority of sockets the parent holds.

The previous code was too subtle, and tried to filter via two xfail
scripts. The --fail-immediately for the source3 knownfail would then
fail samba4 know failures.

This means that we control the connection setup, don't rely on signals
for timeouts and the connection uses socket_wrapper where that is
required in our test environment.
According to bug reports, this method is also used by curl and other
tools, so we are not the first to (ab)use the OpenLDAP libs in this
way.
It is ONLY enabled for socket_wrapper at this time, as this is the
best way to get 'make test' working for S3 winbind tests in an S4
domain.

This avoids these routines doing a DNS lookup that has already been
done, and ensures that the emulated DNS lookup isn't thrown away.

This ensures we follow the dynconfig convention for the socket
directory, and makes it easier to ensure that the client and server
both refer to the same socket.

Looking for smb.conf files with find -name \*.conf would find and not
find all sorts of things that were just not valid inputs. When
restricted to under source3 it then finds no inputs in the top level
build, as it only worked on the generated smb.conf files from 'make
test' environments.
Instead, just run it on the one file we know is valid, and if we want
to run it on more files, then we can make this test run against more
environments, or specific target files.

This is constant data according to the man pages I find for this
fucntion, and causes a segfault to free() when linked to Heimdal. I
am advised that while it is constant for gss_mech_krb5, it may not be
for other mechanisms, so an assert will ensure this is dealt with by
the programmer who extends this code in future.

This only works for Heimdal and MIT Krb5 1.8, other versions will get
an ACCESS_DEINED error.
We no longer manually verify any details of the PAC in Samba for
GSSAPI logins, as we never had the information to do it properly, and
it is better to have the GSSAPI library handle it.

With newer GPFS releases, libgpfs contains a function
gpfs_lib_init(). It marks the pseudo-device the lib uses
as interface to the GPFS kernel module to not be to
destroyed after each call to GPFS.
This saves us some microseconds creating and removing the device
each time we do a call to libgpfs.

We have winbindd write a custom krb5.conf or use a kdc locator plugin
to do this properly now.

By reworking the 'fake DNS' file to use struct dns_rr_srv it should be
possible to emulate that resolver layer as well as the Samba4
sockaddr_storage* based layer. This will then give us a common DNS
emulation for 'make test'.
