Bumps signal-hook from 0.3.18 to 0.4.5.

Changelog

Sourced from signal-hook's changelog.

0.4.5

• pipe::register_raw now really sets close-on-exec (FD_CLOEXEC) on the file descriptor, for both pipes and sockets (#206).
• Removed the 32-bit Android sigemptyset/sigaddset fallback, which panicked in emulate_default_handler (#207). Android below API 21 is no longer supported.

0.4.4

• Documentation about SIGBUS (#204).

0.4.3

• Don't exclude .c files from release package.

0.4.2

• Fix double-close on pipe unregister (#200).
• Don't include development scripts in release package (195).

signal-hook-mio-0.3.0

signal-hook-tokio-0.4.0

signal-hook-async-std-0.4.0

• Release to bump dependency on signal-hook.

0.4.1

• Don't pin specific dependency versions accidentally.

0.4.0

• Changed the low_level::pipe to look OwnedFd instead of IntoRawFd, to enforce ownership of the file descriptor (#196).

signal-hook-registry-1.4.8

• Restore errno on signal handler exit (#194, #191).

signal-hook-registry-1.4.7

• Using earlier monopolization to reduce binary size (#190).

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
