Modified Files:
	src/bin/ls: Makefile extern.h ls.c
Added Files:
	src/bin/ls: main.c
Log Message:
Rename ls.c::main() -> ls.c::ls_main(), and add a wrapper in main.c::main().
This allows other programs to link in against ls (e.g, ftpd), without having
to have hacks to deal with multiple main()s.

Yes, I know this is ugly. The clean alternative (move lots of this
into libutil, yada yada yada) isn't fun, and the effort probably isn't
justified...
