Joachim Nilsson f277166354 sig.c: Use watchdogd to reboot system 
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.

Joachim Nilsson f55f68d032 Cleanup and refactor of public plugin API 
Improve upon API names, both internal and external, to make it clearer
where methods are located and clarify responsibility.

Add new Makefile target "dev" to create untagged development snapshots.

Bump version for upcoming release.

Joachim Nilsson fbfffbc9a4 Eliminate name clash with system signal.h header file. 
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]
