Remove @my_libs@ from imlib2-config
Fix detecting OpenSSL, in particular on OS X.
Add options for qemu and xen, and disable all by default.

Before, anita depended on qemu0 or qemu.  Now, it has options for
qemu-0, qemu (currently 2) and xen (currently 4.1).  By default, all
are off because all of them are quite large and they need only be
present at run time.

Discussed with gson@, who did not object.
Fix building with newer giflib.
Fixes for Darwin
Changes 1.9.4:
- auerswald
  - Fix several potential security issues in the NAS server.
    See http://radscan.com/pipermail/nas/2013-August/001270.html for
    a description. In addition, CVE numbers have been defined for
    these issues:
    CVE-2013-4256
    CVE-2013-4257
    CVE-2013-4258
  - Fixed some warnings while building some of the clients.
  - narrow a possible race condition in
    auvoxware.c:disableProcessFlow() reported by Paul Fox.
- steve_mcintyre
  - add a format string to aulog.c (found using -Wformat-security warnings)
  - Don't preprocess man pages
- Add proper includes in server/os/connection.c to prevent some
  compile warnings and a possible server coredump under the right
  conditions on x86_64 Linux systems.
Changes 1.19.0:
- Support float and 32/24 bit integer output also with fixed-point decoders (conversion from 16 bit precision).
- A-Law output encoding is actually implemented now (Michael introduced the encoding back in the old days without ever implementing theconversion table, apparently).
- Added --with-cpu=arm_fpu as decoder choice for runtime switch between plain fpu code and NEON.
- Fix ARM builds to work properly on debian systems without special CFLAGS (NEON decoder, specifically).
- Make scripts/benchmark-cpu.pl check the return value instead of delivering crazy timings for crashed mpg123.
- Trigger track initialization in mpg123_info() to avoid use of uninitialized variables (watch out for MPG123_NEED_MORE return value!).
- Fix integer code to 32 bit numbers where it would waste 64 bit on modern systems.
- Add non-executable stack marking also to ARM assembly.
Makefile
Removed audio/libmpg123.
Justification:
- nothing depends on it
- hasn't been updated for over 7 years
- use audio/mpg123 instead
Updated audio/mpg123 to 1.19.0
Update x11/x3270 to 3.3.14ga11

Upstream changes
----------------

Changes in version 3.3.14ga10, 27. April 2014

    [x3270] Restored the ability to use the special 3270 fonts with code
 page 1047.

Changes in version 3.3.14ga9, 13. April 2014

    [all 3270] Fixed a crash when disabling tracing after opening the
 trace file fails.

Changes in version 3.3.14beta8, 31. March 2014

    [all 3270] Changed the keyboard to unlock when a BIND-IMAGE is received.
 This matches the behavior of PCOMM and is consistent with some comments
 found on IBM webpages. The net result is that the keyboard will be unlocked
 (and scripts may be allowed to proceed) earlier than with previous versions
 of the emulators. This is good for talking to hosts that don't send an initial
 Write command (as can happen with CICS); previously this Write was the only
 trigger for unlocking the keyboard at connect or BIND time. But it is bad if a
 script implicitly depended on the old behavior. Scripts confused by this change
 may need to add a Wait(InputField) to cover these cases.
    [all 3270] Got rid of the E status for keyboard lock in the scripting prompt.
 The status is now L (locked) or U (unlocked).
    [all 3270] Added decoding of UNBIND reasons to traces.
    [all 3270] Increased the number of situations where keyboard input can result
 in typeahead instead of drops.

Changes in version 3.3.14ga6, 23. January 2014

    [all] Fixed a problem with displaying text in NVT mode when the host does
 no TELNET negotiation.
    [all] Deprecated the dsTrace and eventTrace resources (and associated
 toggles and x3270 menu options) and replaced them with a new single trace
 resource and toggle. The old resources and toggles are still available, but
 are effectively aliases for the new single setting.

Changes in version 3.3.14alpha5, 30. December 2013

    [x3270] Turned the scrollbar on by default. Mapped the PageUp and
 PageDown keys to the (new) Scroll action, to scroll up or down one screen,
 respectively. Modified the Reset action to cancel any screen scrolling.
    [all Windows] Got everything to build under MSVC again, using either
 the command line or MS Visual Studio. A Visual Studio solution file is now
 included in the source tarball. Windows targets also cross-compile again
 with the latest Cygwin MinGW.

Changes in version 3.3.14alpha4, 21. December 2013

    [all] Added a printTextScreensPerPage resource to control how many
 screens of text are displayed per page when tracing screens to the printer.
    [all] Corrected screen tracing to the printer so it observes the
 printer.name and printer.command resources.

Changes in version 3.3.14alpha3, 16. December 2013

    [all, wc3270] Fixed problem with message display during file
 transfers initiated by scripts.
    [all] Fixed a problem reading files with the Source action, when the
 file does not end with a CR or NL.

Changes in version 3.3.14alpha2, 4. November 2013

    [all] Added support for CICS IND$FILE file transfers.

Changes in version 3.3.14alpha1, 30. October 2013

    [all] Allow file transfers to start when the screen is unformatted.
    [all] Fixed a problem with the initial data stream trace snapshot
 when the screen is unformatted.
    A wrapper function was put around the Windows snprintf function,
to ensure that it always NUL-terminates strings. The lack of such a
 wrapper could lead to string overflows in some situations.
