cli: taking my revenge for forcing "geo-replication" into commandline

Accept unambigous initial fragments of keywords, eg.

  gluster vol geo stat

is recognized. Compared to readline integration:

- no external dependency
- works in shell too
- works for inner keywords of operations
  (as in above example, or "vol crea <vol> repl 3 ...")
- you save pressing tabs :)

If not desired in customer builds, can be disabled by an #ifdef
(not integrated into build system as of now); however, I think
folks in house could like it.
