Changes since 1.17: +8 -2 lines 

Clean up the includes in mg.
This does the following:
Moves all POSIX headers from sysdef.h into the individual .c files so that
each file now only includes what it needs. All headers are properly sorted.
Moves the remainder of sysdef.h to other files (mostly def.h) and deletes
sysdef.h now that it's no longer contains anything.
Tweak a comment that references sysdef.h so that it no longer does that.
