Description

Patches adding functionality to the C client library often want to make these new capabilities available/explorable via the cli.c shell.

Examples include ZOOKEEPER-1112 (SASL; the original patchset included a duplicated cli_sasl.c) and ZOOKEEPER-2122 (SSL; the current PR switches it to use getopt).

This ticket is about adding /optional/ getopt support to cli.c without breaking existing uses, and would be a prerequisite for extensions which "require" new flags.
