Prior to this change, wcstoi("0x") would fail with missing digits.
However strtoul will "backtrack" to return just the 0 and leave the x as
the remainder. Implement this behavior.
Prior to this change, wcstoi() would return an error if the requested
type were unsigned, and the input had a leading minus sign. However this
causes problems for printf, which expects strtoul behavior.
Add "modulo base" behavior which wraps the negative value to positive.
Factor this into an option; the default is False (but code which
previously used strtoull directly should set it to true).
fish_wcstoi_partial is like fish_wcstoi: it converts from a string to an
int optionally inferring the radix. fish_wcstoi_partial also returns the
number of characters consumed.
Unfortunately we cannot use wide string literals in match statements
(not sure if there's an easy fix).
Because of this, I converted the input to UTF-8 so we could use the match
statement. This conversion is confusing, let's skip it.
This can be triggered on linux with:
```js
import { spawn } from 'child_process';
const shell = spawn('/home/alfa/dev/fish-shell/build-c++/fish', []);
```
Under node 19.8.1.
*No clue* how that happens, but since this is a workaround we shall
skip it.
Add completions for ssh-copy-id.
Refactored __ssh_history_completions into its own file for autoloading across
completions.

CHANGELOG.rst
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.
Signal is a newtype around NonZeroI32. We could use NonZeroU8 since all signal
values comfortably fit, but using i32 lets us avoid a fallible attempt at
narrowing values returned from the system as integers to the narrower u8 type.
Known signals are explicitly defined as constants and can be matched against
with equality or with pattern matching in a `match` block. Unknown signal values
are passed-through without causing any issues.
We're using per-OS targeting to enable certain libc SIGXXX values - we could
change this to dynamically detecting what's available in build.rs but then it
might not match what libc exposes, still giving us build failures.
This should be used in lieu of manually targeting individual operating systems
when using features shared by all BSD families.
e.g. instead of
#[cfg(any(target_os = "freebsd", target_os = "dragonflybsd", ...))]
fn foo() { }
you would use
#[cfg(feature = "bsd")]
fn foo() { }
This feature is automatically detected at build-time (see build.rs changes) and
should *not* be enabled manually. Additionally, this feature may not be used to
conditionally require any other dependency, as that isn't supported for
auto-enabled features.
