Update gles+osgjs.



This PR

    cleans some gles coverity defects (remaining should only be false positive that need to be sorted out cleanly)
    updates osgjs plugin to support serialization; the history of changes is squashed; details can still be found on cedricpinson fork if needed

As compressed animation channels are no longer part of the main repo, I added a compilation flag for the osgjs plugin. The commit is isolated and the flag is not activated by default.
I am yet to find a better solution to make this plugin entirely free from our specific code.

Note: this PR will not change the gles compilation issues. We only compile on OSX/ubuntu and did not encounter any issue with the plugin.
