Improvements to jim configure

Create and use config.h
Check for backtrace, fork, vfork, syslog, regcomp and others
Disable extensions which require missing functions/features
Check for one arg vs. two arg mkdir()
Distinguish between mingw and native windows
The aio extension has reduced functionality for ANSI C only
