finit.c:
o Perform signal setup as soon as possible, no need to do any
mounting of /proc or /sys beforehand
o Move signal setup and callbacks to a file of its own
o Use more #defines for hard coded strings
o Use a more neutral default hostname
signal.c:
o New file, for setup and signal handlers
o Add support for SIGSTOP/SIGSTP and SIGCONT. This pauses finit
respawning of xinit/shell. Useful for, e.g., debugging
o Document each ignored and handled signal better
o Disable SIGUSR1 and SIGUSR2 for now, will be reenabled later
