Nix, the purely functional package manager
6208ca7209
Most of this is a `catch SysError` -> `catch SystemError` sed. This is a rather pure-churn change I would like to get out of the way. **The intersting part is `src/libutil/error.hh`.** On Unix, we will only throw the `SysError` concrete class, which has the same constructors that `SystemError` used to have. On Windows, we will throw `WinError` *and* `SysError`. `WinError` (which will be created in a later PR), will use a `DWORD` instead of `int` error value, and `GetLastError()`, which is the Windows equivalent of the `errno` machinery. Windows will *also* use `SysError` because Window's "libc" (MSVCRT) implements the POSIX interface, and we use it too. As the docs describe, while we *throw* one of the 3 choices above (2 concrete classes or the alias), we should always *catch* `SystemError`. This ensures no matter how the implementation changes for Windows (e.g. between `SysError` and `WinError`) the catching logic stays the same and stays correct.
