Basic Alembic support All in all, this patch adds an Alembic importer, an Alembic exporter, and a new CacheFile data block which, for now, wraps around an Alembic archive. This data block is made available through a new modifier ("Mesh Sequence Cache") as well as a new constraint ("Transform Cache") to somewhat properly support respectively geometric and transformation data streaming from alembic caches. A more in-depth documentation is to be found on the wiki, as well as a guide to compile alembic: https://wiki.blender.org/index.php/ User:Kevindietrich/AlembicBasicIo. Many thanks to everyone involved in this little project, and huge shout out to "cgstrive" for the thorough testings with Maya, 3ds Max, Houdini and Realflow as well as @fjuhec, @jensverwiebe and @jasperge for the custom builds and compile fixes.

Alembic: integrate cache file into the dependency graph * The cache file datablock is now evaluated as part of the dependency graph, creating/freeing the Alembic file handle matching the current frame. Modifiers and constraints depend on this evaluation. * Cache file handles and readers now only exist on COW datablocks, never the original ones. * Object data paths are flushed back to the original for the user interface. * The cache file keeps a list of all readers associated with its handle, and automatically frees them when the handle is freed.

Fix over creation of cache files handles (leading to memory leaks). Multiple threads could create multiple handles for the same cache file, so protect handle creation with a mutex, to make sure only one is created.

Alembic: store a pointer to the object reader in the cache modifiers and constraints. This avoids traversing the archive everytime object data is needed and gives an overall consistent ~2x speedup here with files containing between 136 and 500 Alembic objects. Also this somewhat nicely de- duplicates code between data creation (upon import) and data streaming (modifiers and constraints). The only worying part is what happens when a CacheFile is deleted and/or has its path changed. For now, we traverse the whole scene and for each object using the CacheFile we free the pointer and NULL-ify it (see BKE_cachefile_clean), but at some point this should be re-considered and make use of the dependency graph.
