Reduce stack usage by ~0.5k
main() uses ~0.5k of stack for local variables and such. When we enter
main tracing loop, most of these variables are no longer used.
But they still take up stack for the entire life of strace.
We can avoid this wastage if we move init code into a separate function.
(Need to be careful and not allow automatic inlining).
* strace.c (init): New function. Most of pre-existing code of
main is now living here.
(main): Call init() to do initialization.
