03571b82be cleanup env code and contains()
Switch from null terminated arrays to `wcstring_list_t` for lists of
special env var names. Rename `list_contains_string` to `contains` and
modify the latter interface to not rely on a `#define`.

Rename `list_contains_string()` to `contains()` and eliminate the
current variadic implementation. Update all callers of the removed
version to use the string list version.

509ee64fc9 implement our own assert() function
I recently upgraded the software on my macOS server and was dismayed to
see that cppcheck reported a huge number of format string errors due to
mismatches between the format string and its arguments from calls to
`assert()`. It turns out they are due to the macOS header using `%lu`
for the line number which is obviously wrong since it is using the C
preprocessor `__LINE__` symbol which evaluates to a signed int.

I also noticed that the macOS implementation writes to stdout, rather
than stderr. It also uses `printf()` which can be a problem on some
platforms if the stream is already in wide mode which is the normal case
for fish.

So implement our own `assert()` implementation. This also eliminates
double-negative warnings that we get from some of our calls to
`assert()` on some platforms by oclint.

Also reimplement the `DIE()` macro in terms of our internal
implementation.

Rewrite `assert(0 && msg)` statements to `DIE(msg)` for clarity and to
eliminate oclint warnings about constant expressions.

Fixes #3276, albeit not in the fashion I originally envisioned.

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.

1fb8f4e277 lint: misc cleanups
Earlier lint cleanups overlooked a couple of modules because on macOS at
the moment oclint ignores them. I noticed this when I ran `make lint-all`

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`desc_arr` variable which is both unused and out of date with reality.

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.

46840ae375 another wcstring to wchar_t * change
In keeping with the change made by @ridiculousfish earlier today modify
the `keyword_description()` function to return a const wchar_t pointer.

Also, simplify the `token_type_description()` function to use the recently
introduced mapping array. This changes the wording of many of the token
type descriptions. However, I can't see this as being a problem since
the original descriptions (e.g., "token_redirection") are no clearer to
someone not acquainted with the implementation.

59f0261dba enhance fish_indent to normalize keywords
Fish keywords can be quoted and split across lines. Prior to this change
`fish_indent` would retain such odd, obfuscated, formatting. This change
results in all keywords being converted to their canonical form.

This required fixing a bug: the keyword member of parse_node_t wasn't being
populated. This hadn't been noticed prior to now because it wasn't used.
