88d2d54276 Stop printing help summary on error
This now displays

- the error message

- a (significantly shorter) backtrace

- A call to open `help $cmd` if necessary

See #5434.
Fixes #3404.

f92c2921d2 Remove mini() and maxi()
C++11 provides std::min/std::max which we're using all over,
obviating the need for our own templates for this.

util.h now only provides two things: get_time and wcsfilecmp.
This commit removes everything that includes it which doesn't
use either; most because they no longer need mini or maxi from
it but some others were #including it unnecessarily.

b13ee818d2 Some early cleanup of tokenizer
Prior to this the tokenizer ran "one ahead", where tokenizer_t::next()
would in fact return the last-parsed token. Switch to parsing on demand
instead of running one ahead; this is simpler and prepares for tokenizer
changes.

e6e1805c5f another step in fixing issue #3985
This changes all of the builtins to behave like `string` to return
STATUS_INVALID_ARGS (121) if the args passed to the command don't make
sense. Also change several of the builtins to use the existing symbols
(e.g., STATUS_CMD_OK and STATUS_CMD_ERROR) rather than hardcoded "0"
and "1" for consistency and to make it easier to find such values in
the future.

Fixes #3985

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.

a928517e95 improve converting strings to ints/longs
The existing code is inconsistent, and in a couple of cases wrong, about
dealing with strings that are not valid ints. For example, there are
locations that call wcstol() and check errno without first setting errno
to zero. Normalize the code to a consistent pattern.  This is mostly to
deal with inconsistencies between BSD, GNU, and other UNIXes.

This does make some syntax more liberal. For example `echo $PATH[1 .. 3]`
is now valid due to uniformly allowing leading and trailing whitespace
around numbers. Whereas prior to this change you would get a "Invalid
index value" error. Contrast this with `echo $PATH[ 1.. 3 ]` which was
valid and still is.

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.

df10b53c0c restyle builtin modules to match project style
Now that the IWYU cleanup has been merged compile all, not just a couple, of
the builtin modules independent of builtin.cpp. That is, no longer `#include
builtin_NAME.cpp` in builtin.cpp. This is more consistent, more in line with
what developers expect, and is likely to reduce mistakes.

Reduces lint errors from 384 to 336 (-13%). Line count from 6307 to 4988 (-21%).

Another step in resolving issue #2902.

Remove the "make iwyu" build target. Move the functionality into the

c1bd3b5824 Eliminate global variables associated with builtin IO
This change eliminates global variables like stdout_buffer. Instead we wrap up
the IO information into a new struct io_streams_t, and thread that through
every builtin. This makes the intent clearer, gives us a place to hang new IO
data, and eliminates the ugly global state management like builtin_push_io.
