Define the CMake cache variable, with empty string as its default.

Make build.sh pass the BUGSPLAT_DB environment variable as a CMake
command-line variable assignment.

Change CMake 'if (DEFINED ENV{BUGSPLAT_DB})' to plain 'if (BUGSPLAT_DB)'.

Make CMake pass new --bugsplat switch to every one of SIX different
invocations of viewer_manifest.py.

Give llmanifest.main() function an argument to allow supplementing the base
set of command-line switches with additional application-specific switches.

In viewer_manifest.py, define new --bugsplat command-line switch and pass to
llmanifest.main(). Instead of consulting os.environ['BUGSPLAT_DB'], consult
self.args['bugsplat'].

Produce CMake message when BugSplat is engaged so we can detect in build log.

Don't try to copy BugSplat DLLs when NOT engaged.

Missed a place in the Copy3rdPartyLibs.cmake file (thank Windows Find) that needs to differentiate between 32 and 64 bit Windows builds

Fix for MAINT-7131 Unable to start the x64 Viewer on Windows 8.1 x64.  This appears to be because two of the MS DLLs we ship with the 64 bit viewer are 32bit. Manually replacing them with their 64 bit equivalents allowed the viewer to start on Windows 8.1.  The change forces the cmake file which copies the DLLs to look in C:\windows\SysWOW64 for 32 bit versions and C:\windows\system32 for 64 bit versions. (yes really).

Generalize Copy3rdPartyLibs.cmake to eliminate some clone-and-tweak redundancy.

The .dylib files in the Linux Vivox package were erroneous to start with;
while the affected changeset bypassed copy errors, it too was wrong. Now that
the Linux Vivox package contains Linux .so files, revert to the correct
filenames to copy.

Updating SDL to 290561, c-ares to 290399, Boost to 290566, colladadom
to 290576, curl to 290567, fontconfig to 290569, freetype to 290557,
google-mock to 290574, libpng to 290558, libxml2 to 290562, llqtwebkit
to 290578, openssl to 290560, PCRE to 290406, zlib to 290556.  Document
compiling and linking in new 00-COMPILE-LINK-RUN.txt in indra/cmake.  It
is the README for the building process based on things learned during
this library project.  Switch building process back to style used for
new llqtwebkit2 repo.  This builds shared libraries for Qt4 products
on all platforms using current build machines and TC task templates.
All platforms are building.  All have comparable FPS rates.  Builds are
getting quieter.  Forward, comrades!

colladadom to 290229, curl to 290186, fontconfig to 290258, freetype to 290255,
google-mock/gmock/gtest to 290199, libpng to 290081, libxml2 to 290157,
llqtwebkit to 290262/250147 (to be fixed shortly), openssl to 290083,
pcre to 290150, zlib to 290080.  The freetype2 headers are now normalized
to what they would normally be on a unix-type system.  Libxml2 and
pcre are available on all platforms.  Libraries generally move in the
direction of static archives rather than shared libraries (e.g. openssl).
The llqtwebkit side is a step back from the more ambitious goal.  What
will be used (290262) will be a simple rebuild of the existing 4.7.1
library with updated package dependencies.  The bigger work will be in
the future.

Update library dependencies to reference builds using new templates and
modern build hosts for:  SDL, c-ares, boost, curl, libpng, llqtwebkit2,
openssl and zlib.  Update manifest, library copying and 'test_apps' setup
to reflect that zlib and openssl are now always static (on Mac and
Linux).  Viewer and test_apps now functional on 10.7 Mac.

Part of the switchover to dynamic Qt4.  This mostly completes the
Mac side.  Webkit is functional on Mac, plugins work.  The two
test programs, llfbconnectest and llplugintest, need a little
more work to run without manual fixup ('.' on PATH and maybe a
symlink to libz.1.dylib and they run and function on Mac).  Also
need to address libz.dylib vs libz.a.  Currently resolving against
dylib which is not what I want.

openssl on Mac (copy, deploy).  Revert Linux manifest work which tried
to work around 0555 permissions on .sos (and didn't work).

SDL to 1.2.15, c-ares to latest 1.10.0 build, Boost to 1.55.0
with coroutine updates/fixes, curl to 7.34.0, libpng to 1.6.8,
openssl to 1.0.1e, zlib to latest 1.2.8 build, llqtwebkit
built from 4.7.1 sources refactored and tested in 3p-llqtwebkit2
repository.

Windows is functional with a good number of warning messages
at runtime from libpng and KDU.  MoaP/slplugin functioning.

Copy3rdPartyLibs needed to copy the now-corrected fmodexL libraries
and it had a bad library reference on Linux for release.  In
llaudio land, the audio engine interfaces, even the fmodex
specializations, seem to want to be external-structure free
so use a forward declaration and pointer to FMOD_DSP_DESCRIPTION
and deal with it in the ctor/dtor.
