82b4d7225c env_get_runtime_path: Check for getpwuid() failure
Otherwise this is a NULL dereference and then crash.

Fixes #5550.

3cc581fbb0 Unconditionally set the tty mode in reader_readline
There was a bogus check for is_interactive_session. But if we are in
reader_readline we are necessarily interactive (even if we are not in
an interactive session, i.e. a fish script invoked some interactive
functionality).

Remove this check.

Fixes #5519

1680b741b2 Make while loops evaluate to the last executed command status
A while loop now evaluates to the last executed command in the body, or
zero if the loop body is empty. This matches POSIX semantics.

Add a bunch of tricky tests.

See #4982

fec10830d3 Correctly handle exited jobs in process_mark_finished_children
This is effectively a pick of 2ebdcf82ee
and the subsequent fixup. However we also avoid setting WNOHANG unless
waitpid() indicates a process was reaped.

Fixes #5438

c66b3128ec Use wcstod_l on NetBSD
It has wcstod_l, but not uselocale, so we can't use the fallback.

3847d2e9d1 Also set the read-only flag for non-electric vars
For some reason, we have two places where a variable can be read-only:

- By key in env.cpp:is_read_only(), which is checked via set*

- By flag on the actual env_var_t, which is checked e.g. in
  parse_execution

The latter didn't happen for non-electric variables like hostname,
because they used the default constructor, because they were
constructed via operator[] (or some such C++-iness).

This caused for-loops to crash on an assert if they used a
non-electric read-only var like $hostname or $SHLVL.

Instead, we explicitly set the flag.

We might want to remove one of the two read-only checks, or something?

Fixes #5548.

2abd0cde85 builtin_printf.cpp: remove is_hex_digit, redo is_octal_digit
Our is_hex_digit() was redundant, we can just use iswxdigit; the libc
implementation is a more efficient table lookup anyhow.

Do is_octal_digit() in terms of iswdigit instead of using wcschr.

2bb53f7253 Fix locale_t under macOS 10.10
`xlocale.h` is not available on Linux, so we can't just universally
include it.

`HAVE_XLOCALE_H` was already being tested/set in the CMake script as a
possible requirement for `wcstod_l` support, this just adds it to
`config_cmake_h.in` and uses it in `wutil.h` to gate the include.
