util.signal: Implement signalfd for *BSD
...
The Lua hook based signal handling does not work correctly if signal
handling is setup in a coroutine. signalfd solves that in a nice way,
but is Linux-only.

util.signal: Fail signalfd() if unable to change signal mask
...
By aborting early, the failure should be brought to the attention
somehow.

util.signal: Add support for signalfd(2) on Linux
...
signalfd allows handling signal events using the same method as sockets,
via file descriptors. Thus all signal dispatch can go through the same
main event loop as everything else, removing need for thread-scary
signal handling where execution would just jump to the signal handler
regardless of the state of Lua, and needing to keep track of Lua
states/threads.

util.pposix,signal: Pass around various OS numbers as integers [Lua 5.3]
...
Passing around PIDs, UIDs etc as integers makes it more sane in Lua 5.3.
Getting 1234.0 as PID is silly. Shouldn't change any behavior as these
are all integers on the C side and the integral floats are accepted as
integers when passed back from Lua into C.
