[UPnP] tidy up device names & versions
[UPnP] Platinum now ignores local devices by default now
[UPnP] We already used multicast to discover devices, remove confusing comments & unused variable
[UPnP] Platinum now stats files before serving via http. This means serving files from vfs was broken. Solution is to remove all filesystem access to Platinum and expand NPT_XbmcFile. Anything apart from GetInfo:: (stat) is ignored as Platinum only serves up library items, not file systems. Thanks to elupus for fix, and pieh for spotting this in the first place
Merge pull request #1230 from alcoheca/upgrade-platinum

[gsoc] [UPnP] Upgrade Platinum
[win32] fix build after e195496
[osx] - fix osx xcodeproject (remove unneeded framework and resorted the upnp stuff)
[osx] - readded the framework (was indeed needed) - to the correct place in the project
[ios/atv2] - sync xcode projects for the upnp bump
[GSOC] Add latest snapshot of google test (r619).
[GSOC] Add gtest directory to be bootstrapped.
[GSOC] Add files from gtest to be ignored by git.
[GSOC] Have the testsuite built when the 'check' target is invoked.
Support a separate target named 'testsuite' which builds the test suite
without running it.

Also note that a configure option (--enable-gtest) must explicitely
be set in order to configure the Google Test Framework. If it is
not set, running the 'check,' 'testsuite,' or 'testframework,'
make targets will simply display a message saying the framework
has not been configured.
[GSOC] Port xbmc/threads/test test cases to use Google test framework.
[GSOC] Use google test for xbmc/utils/test test cases.
