f2cf54608d Migrate existing rust code to Signal type
Everything but signal handlers has been changed to use `Signal` instead of
`c_int` or `i32` signal values.

Event handlers are using `usize` to match C++, at least for now.

47b4e3d067 fixup! Switch signals from usize to i32
Just address two clippy lints that are fallout from changing the signal type.
There's no longer any need to convert these (which gets rid of an unwrap).

161734f310 Remove bitset module
This was added to support signals; however we are unlikely to use this
for anything else. Remove it; just use a u64 to report signals that have
been set.

6809a8dfbc Use a bit set for pending signals
This optimizes over both the rust rewrite and the original C++ code. The rust
rewrite saw `std::bitset` replaced with `[bool; 65]` which could result in a
lot of memory copy bandwidth each time we checked for and received no signals.
The original C++ code would iterate over all signal slots to see if any were
set. The code now returns a single u64 and only checks slots that are known to
have signals via an intelligent `Iterator` impl.
