(stp_main_loop): Call cleanup_and_exit() when STP_EXIT
is received. Don't send a request for the transport

* elaborate.cxx: Temporarily disable verbose variable access.
* main.cxx: Support more arguments, build/run passes. Revamp
temporary file generation and partial-pass output generation.
* tapsets.cxx, translate.cxx: Emit just enough extra punctuation
and fluff to make generated probe pass -Werror.
* buildrun.cxx, buildrun.h: New files for passes 4/5. Partial
support for build pass, nothing on probe execution yet.
