There are now many better ways to access a remote SMB filesystem,
which do not rely on LD_PRELOAD and the associated dangers.  FUSE,
gvfs and the CIFS VFS are all much better options which do not require
knowing every possible libc entry point that can deal with a file
descriptor.

As an example of the maintainence that would be required to keep this
going, recent changes to deal with thread races and close-on-exec have
resulted in dup3(), but this isn't currently mapped.  While this would
not be hard to add, it illistrates why it is better to move to an
interface designed for this task.

This corrects the issues reaised in bug #6129, and some others that were not
originally identified.  It also accounts for some code that was in the original
bug report but appears to have since been made common between S3 and S4.

Thanks to Erik Hovland <erik@hovland.org> for the original bug report.

smbsh.c is located in the examples directory. It does not make sense
to install a man page without installing the tool itself.

This fixes bug #4724.

- talloc and tdb have been moved to separate libraries.  Link with those.

The libsmbclient interface has suffered from difficulty of improvement and
feature enrichment without causing ABI breakage.  Although there were a number
of issues, the primary ones were:

(a) the user of the library would manually manipulate the context structure
    members, meaning that nothing in the context structure could change other
    than adding stuff at the end;

(b) there were three methods of setting options: setting bits in a flags field
    within the context structure, setting explicit options variables within an
    options structure in the context structure, and by calling the
    smbc_option_set() function;

(c) the authentication callback did not traditionally provide enough
    information to the callee which required adding an option for a callback
    with a different signature, and now there are requests for even more
    information at the callback, requiring yet a third signature and option to
    set it (if we implement that feature).

This commit provides a reorganization of the code which fixes (a) and (b).
The context structure is now entirely opaque, and there are setter and getter
functions for manipulating it.  This makes maintaining ABI consistency much,
much easier.

Additionally, the options setting/getting has been unified into a single
mechanism using smbc_option_set() and smbc_option_get().

Yet to be completed is a refactoring of the authentication callback (c).

The test programs in examples/libsmbclient have been modified (if necessary;
some applications require no changes at all) for the new API and a few have
been minimally tested.

GetTimeOfDay() seems to no longer be exported.  For the smbsh example, just
use the native gettimeofday() for now.
