xlator options: revamp xlator option validation/reconfigure code
- move option handling to options.c (new file) - remove duplication of option validation code - remove duplication of gf_log / sprintf - get rid of xlator_t->validate_options - get rid of option validation in rpc-transport - get rid of validate_options() in every xlator - use xlator_volume_option_get to clean up many functions - introduce primitives to init/reconfigure option types Change-Id: I51798af72c8dc0a2b9e017424036eb3667dfc7ff BUG: 3415 Reviewed-on: http://review.gluster.com/235 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@gluster.com>
