Signal handling library

Docs | Github | Crate

The library is focused on higher-level abstractions for handling signals. All low-level stuff should be in nix.

Currently we have two mechanisms for handling exeptions:

1. The exec_handler module for replacing process with newly runned command designed as crash safety measure
2. The Trap mechanism that masks out signals and allows wait for them explicitly

Both are specifically suited for making process supervisors.

Note, masking out signals may also be achieved by trap (just don’t call either wait() or next())

On TODO list:

The library tested only on linux
