56e05dab02 another attempt to workaround a glibc bug
This is another attempt to fix issue #3644 that we believe is due to issue
https://sourceware.org/bugzilla/show_bug.cgi?id=20632.

2e9a349dd0 normalize use of stdio functions taking a stream
We should never use stdio functions that use stdout implicitly. Saving a
few characters isn't worth the inconsistency. Too, using the forms such
as `fwprintf()` which take an explicit stream makes it easier to find
the places we write to stdout versus stderr.

Fixes #3728

177e06808c Replace all printf invocations with wprintf
Remember, GNU doesn't allow mixing narrow and wide IO.

b118ed69d3 convert narrow stderr output to wide forms
On some platforms, notably GNU libc, you cannot mix narrow and wide
stdio functions on a stream like stdout or stderr. Doing so will drop
the output of one or the other. This change makes all output to the
stderr stream consistently use the wide forms.

This change also converts some fprintf(stderr,...) calls to debug()
calls where appropriate.

7c40abe4a6 switch from \1xb to \e in the code
Using `\e` is clearer and shorter than `\x1b`. It's also consistent with how
we write related control chars; e.g., we don't write `\x0a` we write '\n'.

396bf1235d workaround glibc bug that can corrupt malloc arena
If an interactive shell has its tty invalidated attempts to write to
stdout or stderr can trigger this bug:

https://sourceware.org/bugzilla/show_bug.cgi?id=20632

Avoid that by reopening the stdio streams on /dev/null if we're getting
an ENOTTY error when trying to do things like give or take ownership of
the tty.

This includes some unrelated style cleanups but including them seems
reasonable.

fa837a2e4a Prevent crash when reaping jobs in exit handlers
If an interactive job is started, and it is reaped within fish's
exit handler, we may attempt to print its status message after
cur_term has been set to NULL. This results in a crash.

This change makes fish only print the status message if cur_term is
not NULL.

d51a1e4fe2 kill CAST_INIT, use reinterpret_cast<> on sockaddr
Just use static_cast directly instead of inscrutible "shortcut"
macro.

It was not always used and doesn't seem to do much besides scramble
things up; encountering CAST_INIT() in the code seems likely to lead
to head scratching due to the transformation taking place.

It was added to save folks typing the type twice, now with 100
columns available, let's roll that convenience macro back.

sockaddr_dl:

Perform reinterpret_cast<sockaddr_dl> conversion. The cast affected
alignment and looks fishy to a compiler (but it's fine). Ditch
C-style cast and communicate we're doing that on purpose.

5bf1b0e5f5 fix random lint issues
This only eliminates errors reported by `make lint`. It shouldn't cause any
functional changes.

This change does remove several functions that are unused. It also removes the
`desc_arr` variable which is both unused and out of date with reality.

ff1d651415 rename get_is_interactive and remove stupid test
I'm doing this as part of fixing issue #2980. The code for managing tty modes
and job control is a horrible mess. This is a very tiny step towards improving

1f06e5f0b9 add better support for IWYU and fix things
Remove the "make iwyu" build target. Move the functionality into the
recently introduced lint.fish script. Fix a lot, but not all, of the
include-what-you-use errors. Specifically, it fixes all of the IWYU errors
on my OS X server but only removes some of them on my Ubuntu 14.04 server.

9dd6873e58 lint: remove or comment out unused functions
Cppcheck has identified a lot of unused functions. This removes funcs that
are unlikely to ever be used. Others that might be useful for debugging I've
commented out with "#if 0".

9151ec7092 Eliminate narrow_string_rep_t
This was used to cache a narrow string representation
of commands, so that if certain system calls returned errors
after fork, we could output error messages without allocating
memory. But in practice these errors are very uncommon, as are
commands that have wide characters. It is simpler to do a best-effort
output of the wide string, instead of caching a narrow string
unconditionally.
