xlockmore port improvements patch

        Some time ago I send PR about PAM support in xlockmore. Now
        I spend some time to work on xlockmore. I found that PAM
        works fine by default (with --enable-pam), but only with
        modules that does not requires root rights to authenticate.
        But almost all PAM configurations ends with pam_unix call.
        Here is the trouble. xlock drops root privileges after
        startup. I use BAD_PAM again to wrap this setuid().  IMHO,
        usage of BAD_PAM is right in this case. Also abort trap was
        fixed. Here was error in PAM_conv function. I'll send
        explanations of changes and situation to xlock-discuss
        mailing list later. May be fixes will be committed into
        next release of xlockmore.

At Kris's request, back out the MACHINE_ARCH spelling correction until
after 5.4-RELEASE.

Assist getting more ports working on AMD64 by obeying the
Ports Collection documentation and use 'ARCH' rather than 'MACHINE_ARCH'.

- Add several new X_*_PORT variables which point to various pieces of X11 based
  on the setting of X_WINDOW_SYSTEM, and make ports use them.
- Add information to CHANGES about how to handle the transition.

Don't use bitmap we don't have.

Fix building when MAKE_KERBEROS4 is defined.

Upgrade to 5.03.

Upgrade to 5.02.    

The `--with{,out}-mesagl' option to configure is spelled `--with{,out}-mesa'.   

Add ${KRB5_HOME}/include to $CFLAGS and ${KRB5_HOME}/lib to   $XLOCKLIBS for
people using kerberos5.    

Link against ${PTHREAD_LIBS} if we want MESAGL. Mesa is now compiled   with
thread support also on XFree86-3 systems.    

Add a knob to disable the `allow-root' functionality, which lets root   unlock
the screensaver regardless of the current owner.    

Upgrade to 5.01.    

Add ${PTHREAD_LIBS} to the libs to fix building on XFree86-4.    

Style fixes for ports/x11.    

Upgrade to 5.00.    

Convert category x11 to new layout.  

Use new variable XFREE86_VERSION.    

Upgrade to 4.17.1. This release contains the security fix in patch-sec1.    

Make this at least compile for XFree86-4.0.1.    

Fix a local root exploit in xlock    

Upgrade to 4.17.    

(1) Add new variable, XFREE86_VERSION, to specify which version of       XFree86
(3 or 4) to depend to when USE_XLIB is set.       XFREE86_VERSION defaults to 3
for now, but adventurous users can       override it in /etc/make.conf.  When
XFREE86_VERSION=3, USE_XLIB       will add a dependency to x11/XFree86; when it
is set to 4, the       dependency will be to x11/XFree86-4-libraries.  When     
 XFREE86_VERSION=4, the PKG_IGNORE_DEPENDS and ALWAYS_BUILD_DEPENDS       hacks
to avoid messing with XFree86 are turned off.
