[PATCH v1 00/20] signal: refactor some functions

Hey,

This series refactors a bunch of functions in signal.c to simplify parts
of the code.
As requested, v2 drops all 3 commits that were pure coding-style
changes. The only other coding-style change is the simplification of
rt_sigaction which seemed to be worth keeping.
The greatest single change is declaring the static do_sigpending()
helper as void which makes it possible to remove a bunch of unnecessary
checks in the syscalls later on.

Thanks!
Christian
