Code cleanups after running with "sparse" Lots of minor warnings picked up: * non-ANSI declarations * static variable declarations and a real bug-fix in exit_if_enabled (use of "0" rather than "o"); could have caused a crash.
Add libjte libjte is made up of the code from cdrkit (genisoimage) with extra wrapper code, automake, etc. provided by George and Thomas. Hopefully ready to work with as a standard shared library.
