This patch traps segfaults caused by 3rd party service callbacks in a
separate process context. Effectively preventing a single programming
mistake from taking down the entire system. Previously it was up to the
callback coder to write error free code so that PID 1 did not crash.

Standard init implementations save current and previous runlevels
in utmp, now finit does too. Also, the initial runlevel at boot
has changed from 10 to the more obvious 0.

This patch reorders the shutdown/reboot handler slightly and fixes
a bug in sleep(). It seems the sleep() syscall was interrupted by
receiving lots of SIGCHLD. Unsurprisingly since we just sent all
processes SIGTERM, but unfortunate since that was too short time
to deliver SIGTERM to watchdogd.
We now call sleep() again, as long as it returns a non-zero value,
until at most two (2) seconds have passed. During this time we
basically pend for watchdogd to do its job and let the WDT reboot
the system. If the two second timeout passes we send SIGKILL and
forcibly reboot(RB_AUTOBOOT) the system.

Improve upon API names, both internal and external, to make it clearer
where methods are located and clarify responsibility.

Tried to solve the signal.h name clash by using #include_next, but
seeing as this is not recommended[1] and breaks builds on some cross
compilers, the files were simply renamed: signal.[ch] --> sig.[ch]
