87a532f533 make it hard to use history command incorrectly

cfefaaf4ee revert the --shadow-builtin flag
Implementing the --shadow-builtin flag has proven to be highly controversial.
Revert the introduction of that flag to the `function` command. If someone
shoots themselves in the foot by redefining a builtin as a function that's
their problem and not our responsibility to protect them from doing so.

Fixes #3319

710addde16 fix history --delete regression
The recent change to reconcile the history builtin command and function
broke an undocumented behavior of `history --delete`. This change
reinstates that behavior. It also adds an explicit `--exact` search mode
for the `--search` and `--delete` subcommands.

Fixes #3270

ee26eafc25 Ensure we continue to cover enums in switches
Where we already manage to cover an enum entirely in a switch
statement such that default: cannot be reached, help ensure
it stays that way by condemning that route.

Also adjust a 'const' I came across that is ignored.

b53f42970c correct handling of history args
This fixes several problems with how the builtin `history` command handles
arguments. It now complains and refuses to do anything if the user specifies
incompatible actions (e.g., `--search` and `--clear`). It also fixes a
regression introduced by previous changes with regard to invocations that
don't explicitly specify `--search` or a search term.

Enhances the history man page to clarify the behavior of various options.

This change is already far larger than I like so unit tests will be added
in a separate commit.

Fixes #3224.

Note: This fixes only a couple problems with the interactive `history
--delete` command in the `history` function. The main problem will be
dealt with via issue #31.

09291735e6 Use locales preferred date format, fix up options
We don't seem to mention in the documentation that we were forcing
-t for all interactive uses. If we want to do that we should apply
that in the builtin.

history.fish reimplementing every option and doing things kind of
differently is a real pain and it's not clear if the docs are
referring to the or the wrapper script or both.

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`desc_arr` variable which is both unused and out of date with reality.

51468b7646 add function --shadow-builtin flag
It's currently too easy for someone to bork their shell by doing something
like `function test; return 0; end`. That's obviously a silly, contrived,
example but the point is that novice users who learn about functions are
prone to do something like that without realizing it will bork the shell. Even
expert users who know about the `test` builtin might forget that, say, `pwd`
is a builtin.

This change adds a `--shadow-builtin` flag that must be specified to
indicate you know what you're doing.

42068931c7 eliminate "useless parentheses" lint errors
Some `oclint` errors regarding "useless parentheses" are meaningfull. But

fc44cffac5 restyle switch blocks to match project style
I missed restyling a few "switch" blocks to make them consistent with the rest
of the code base. This fixes that oversight. This should be the final step in
restyling the C++ code to have a consistent style. This also includes a few
trivial cleanups elsewhere.

I also missed restyling the "complete" module when working my way from a to z
so this final change includes restyling that module.

Total lint errors decreased 36%. Cppcheck errors went from 47 to 24. Oclint P2
errors went from 819 to 778. Oclint P3 errors went from 3252 to 1842.

Resolves #2902.

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
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

c2f1df1d4a fix handling of non-ASCII chars in C locale
The relevant standards allow the mbtowc/mbrtowc functions to reject
non-ASCII characters (i.e., chars with the high bit set) when the locale
is C or POSIX.  The BSD libraries (e.g., on OS X) don't do this but
the GNU libraries (e.g., on Linux) do. Like most programs we need the
C/POSIX locales to allow arbitrary bytes. So explicitly check if we're
in a single-byte locale (which would also include ISO-8859 variants)
and simply pass-thru the chars without encoding or decoding.

Fixes #2802.

ef31aa94f8 clarify the documentation of builtin random
The random builtin command may or may not produce values with a truly
random distribution. So make the documentation reflect that reality. Also,
make the command consistent with similar shells (e.g., bash, zsh) which
produce a range of [0..32767].

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.
