encperf: report encoded & raw-equivalent bytes
Report encoded and raw-equivalent bytes as well as compression ratio (I like
to have these statistics so I can compute overall compression ratios for
groups of datasets in a spreadsheet.)
In earlier Visual Studio and MinGW editions, BSD socket errno:s were
left undefined. This is no longer the case. This may cause build or
runtime errors. To avoid this, we are using a common header file which
corrects all definitions. This header will also be used with other
projects such as sercd, unfs3, PulseAudio etc.

Improved font path specifiecation for el5 & generic binaries.
Font paths were incompletely specified, resulting in font issues with some applications (nedit, for instance). Also, added support for font catalogues back in, even though el5 doesn't supoort it, this should make font handling more robust for the genric binaries.

Fixes for various build issues with el5 build
Fixed various static linking problems with latest el5 spec.
Some definitions were being overridden in StaticBuild.cmake,
causing checks for various fltk capabilities to fail. Also,
fontconfig was not being configured properly for default font
locations, causing the vncviewer to fail to locate fonts when
used as a generic binary.

Major update of EL5 build
The patches required for the 2014-12-09 Xorg CVE advisory would not
have been feasible to back-port to the 1.7 version of Xorg that we
were previously using to built against for EL5 and the generic
binaries. However, building the newer version of Xorg required
some fairly extensive re-tooling. In a nutshell, here's what was
done:
* The build is now done against Xorg X117R7, with all CVE patches
(taken from debian sources) applied. Note that this requires
updating various packages beyond the versions readily available
for EL5. This included things like automake, autoconf, libtool,
m4, and flex. Wherever possible, the EL6 rpm was used unaltered.
The most chalenging package to upgrade was libxml2, which was
necessary to supply the python26-libxml2 requirement from mesa.
* Mesa libGL is now supplied with the package, installed in the
%{_libdir}/tigervnc directory. The Xvnc binary is linked using
an rpath so that we always link against our version of libGL.
This was done to prevent linker errors with the generic binaries
in the case where the distro supplied libGL is built with
different options (in particular, kernel versions < 2.4.20 do
not support glx-tls, so the generic binaries would likely break
whenever used on newer distros that build libGL with glx-tls
turned on by default). Additionally, this allows swrast_dri.so
to be bundled without worrying about overwriting the distro
supplied library.
* A static libsha1 is built for Xorg to link against. The EL5
version of libgcrypt does not satisfy Xorg's requirements,
and linking against OpenSSL creates nearly a dozen runtime
dependencies.

Restructure Xvnc/libvnc.so code to avoid C++ header hacks
The internal Xorg headers are very incompatible with C++ and we've had
to resort to all kinds of hacks in order to include them in our C++
code. This approach isn't really viable long term so restructure things
so that we have a glue layer written in C that bridges the Xorg core
with the RFB classes.

Remove support for openSUSE 11.4
Project Evergreen stopped supporting 11.4 in October and it's not feasible to
back-port the patches for the Xorg 2014-12-09 CVEs, so as a result we can no
longer provide pre-built packages for this distribution. The genric binaries
can be used instead.

Assume inet_pton() is missing on Windows
It's much more difficult to test for this on Windows since the

missing. We can remove this check when we raise the base requirements

Major rework of Java viewer clipboard handling
* Clipboard dialog UI significantly improved.
- Fixes issue where scrollpane size did not track dialog size
- Removed unnecessary JPanel
- Adjusted default size of dialog to something more appropriate.
* Clipboard dialog is now a pure clipboard viewer
- Window title now reflects thati fact.
- Eliminates problems with concurrency and updating contents.
- Clipboard dialog now updates contents if a clipbard transfer
occurs and the dialog is visible.
- Prevents possible loop condition when text in the scrollpane
is selected (ie: selection buffer triggers clipboard updates).
* Custom TransferHandler implemented.
- Limits the size of outbound clipboard transfers.
- On Windows and Linux this implementation does not appear to
provoke huge memory spike issue when the transferable is
accessed. Unfortunately, the OSX implemenation still
suffers from this problem, but that is a JRE issue. For the
time being, this at least minimizes the problem. Additionaly,
if an OutOfMemoryError is thrown, it's now caught and an error
is logged rather than the viewer bailing out.
- Vastly simpler implementation - the copy/paste methods inherent
in the JTextArea are utilized for interfacing with the system
clipboard. This eliminates the need for checking permissions,
as well as streamlining the code quite a bit.
