core: remove all the 'inner' functions in codebase

* move 'dict_keys_join()' from api/glfs_fops.c to libglusterfs/dict.c
  - also added an argument which is treated as a filter function if
    required, currently useful for fuse.

* now 'make CFLAGS="-std=gnu99 -pedantic" 2>&1 | grep nested' gives
  no output.
