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
