std.os.abort: ported signal handling from musl
* Document deviation from Linux man page, which is identical to musl.
Man page wants always enabled user-provided abort handlers.
Worst case logic bug, which this can introduce:
+ user disables SIGABRT handler to prevent tear down to last safe
state
+ abort() gets called and enables user-provided SIGABRT handler
+ SIGABRT tears down to supposed last safe state instead of crash
+ Application, instead of crashing, continues
* Pid 1 within containers needs special handling.
- fatal signals are not transmitted without privileges,
so use exit as fallback
* Fix some signaling bits
* Add checks in Debug and ReleaseSafe for wrong sigprocmask
