* Added new interface BufferCache -- basically a memory allocator with the

option to cache a freed buffer -- and implementations
  BlockBufferCache{NoLock,Kernel}.
* ZlibPackageDataReader does now dynamically get its read and uncompress
  buffers from a provided BufferCache when needed.
* Allocating the buffers once and keeping them over the whole life time was a
  bit too memory heavy, since we create a reader for every file for which a
  vnode is created. A FS module global factory provides a buffer cache.
* Added a mutex to PackageFile::DataAccessor which guards the access to the
  data reader which isn't thread safe.
