Bundle new upstream version of libmv from own branch

This version of libmv includes new gflags and glog libraries which makes
it possible to compile libmv with clang compiler.

Also remove code from CMakeLists which was disabling libmv if using clang.

Tested on linux with gcc-4.6 and clang-3.0, windows cmake+msvc and scons+mingw.
Could be some issues with other platforms/build system which shall be simple to resolve.

+    Replace "third_party/glog/src/glog/logging.h" with <glog/logging.h>
+    
+    It was needed because of how build systems is setup in Blender but think
+    this will be helpful change for other applications too because it makes
+    it's easier to move libraries around and even use libraries installed
+    on the operation system.

+
+    Upgrade gflags and glog libraries - stage 2 (final)
+    
+    Changes to upstream code which are needed to make libmv compile smooth on all platforms
+    
+    * Replace <gflags/gflags.h> with "third_party/gflags/gflags/gflags.h" which is easier
+      to setup things in libmv and also helps with setting up building libmv into
+      external applications.
+    * Replace "glog/logging.h" and  "glog/logging.h" with <glog/logging.h> and  <glog/logging.h>
+      which is needed on Windows platform because otherwise files like logging.cc will be using
+      relative path which points to headers used by linux instead of headers need to be used
+      on Windows.
+    * Replace _asm int 3 with __debugbreak(). Such assembler code is obsolete and doesn't work
+      with 64bit versions of MSVC compilers.
+    * Do not use stacktrace for MinGW and FreeBSD because it leads into issues accessing
+      some specific data on this platforms.
+    * Define HAVE_LIB_GFLAGS for Windows builds.
+    * Do not define __declspec(dllimport) for MinGW platforms.
+    * Setup proper includes and datatypes for int32, uint32, int64 and uint64 for MinGW
+    * Do not define va_copy for MinGW platforms (it's already defined there).
+    * Patch localtime_r to be working fine with MinGW, disable strerror_r for MinGW because
+      of lack of needed functions.

+    Upgrade gflags and glog libraries - stage 1
+    
+    This commit copies sources from latest original release of gflags and glog
+    over currently bundled versions of this libraries without any modifications.
+    
+    This revision can't b compiled, all needed changes to make new libraries working
+    fine will be done with next commit to make it clear which changes were necessary
+    for easier bundling further newer version and extract patches and put them to
+    gflags/glog upstream repo.
+    
+    Such upgrade of libraries is needed to make it able to compile libmv
+    with clang compilers. Currently used versions:
+    
+    - gflags is version 2.0
+    - glog is version 0.3.2
