Subject: Infrastructure for excluding code generators from the Thrift compiler.
X-Git-Tag: 0.2.0~957

Infrastructure for excluding code generators from the Thrift compiler.

Add a new autoconf macro (a thin wrapper around AC_ARG_ENABLE) that
makes it pretty easy to include or exclude specific code genreators.

This will be tested along with future changes that use it.
