Christian Thaeter 232afe77e9 Filehandling
* add 'backend' for backend global initialization/destruction
  and common functions.
* WIP: 'file' acts as interface to named files, provides posix
  filehandles with and acquire/release function pair.
* 'filehandle' manages posix filehandles internally, refcounted.
* WIP: 'filehandlecache' keeps unused filehandles in a MRU cache

* WIP: test for filehandle management
* improved filedescriptor test
