8a033b9f3d Add undo
Add the input function undo which is bound to `\c_` (control + / on
some terminals). Redoing the most recent chain of undos is supported,
redo is bound to `\e/` for now.

Closes #1367.
This approach should not have the issues discussed in #5897.

Every single modification to the commandline can be undone individually,
except for adjacent single-character inserts, which are coalesced,
so they can be reverted with a single undo. Coalescing is not done for
space characters, so each word can be undone separately.

When moving between history search entries, only the current history
search entry is reachable via the undo history. This allows to go back
to the original search string with a single undo, or by pressing the
escape key.
Similarly, when moving between pager entries, only the most recent
selection in the pager can be undone.

18b56637f7 self-insert bindings to insert their own sequence
Prior to this fix, self-insert would always wait for a new character.
Track in char_event what sequence generated the readline event, and then
if the sequence is not empty, insert that sequence.

This will support implementing the space binding via pure readline
functions.

39099ceb10 Remove R_BEGIN_INPUT_FUNCTIONS
The enum starts at 0 (defined to be!), so we can eliminate this one.

That allows us to remove a reliance on the position of
beginning_of_line, and it would trigger a "type-limits" warning.

Also leave a comment because I actually hit that.

edab366d3a Eliminate the "input callback queue"
This was a sort of side channel that was only used to propagate redraws
after universal variable changes. We can eliminate it and handle these

8ff866b26b Add repaint-mode bind function
If we switch the bind mode, we add a "force-repaint" there just to
redraw the mode indicator.

That's quite wasteful and annoying, considering that sometimes the prompt can take
half a second.

So we add a "repaint-mode" function that just reexecutes the
mode-prompt and uses the cached values for the others.

Fixes #5783.

Expand abbr explicitly (#5762)
* Add "expand-abbr" bind function

This can be used to explictly allow expanding abbreviations.

* Make expanding abbr explicit

NOTE: This accepts them for space only, we currently also do it for \n
and \r.

* Remove now dead code

We no longer trigger an abbr implicitly, so we can remove the code
that does it.

* Fix comment

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.

The fish_key_reader program was the only user of the

0461743. So remove it from the main fish code. This was found by `make

f3e93f0666 fix handling input in the C locale
In the C/POSIX locale EOF on the tty wasn't handled correctly due to a change
a few months ago to fix an unrelated problem with that locale. What is
surprising is that the core fish code doesn't explicitly depend on
input_common_readch returning WEOF if a character isn't seen within
`wait_on_escape_ms` after an escape.

b055b8440c enhance the key_reader program
The original `key_reader` program was useful but didn't do much that `xxd`
or `od -tx1z` didn't do. Furthermore, it wasn't built and installed by
default. This change adds features that make it superior to those programs
for decoding interactive key presses and makes it a first-class citizen
like the `fish_indent` program that is always available.

f2246dfb34 reduce number of Unicode private-use characters
This narrows the range of Unicode codepoints fish reserves for its own
use from U+E000 thru U+F8FE (6399 codepoints) to U+F600 thru U+F73F (320
codepoints). This is still not ideal since fish shouldn't be using any
Unicode private-use codepoints but it's a step in the right direction.

This partially addresses issue #2684.

4b9fece9f4 allow configuring the escape delay timeout
Introduce a "fish_escape_delay_ms" variable to allow the user to configure the
delay used when seeing a bare escape before assuming no other characters will
be received that might match a bound character sequence. This is primarily
useful for vi mode so that a bare escape character (i.e., keystroke) can
switch to vi "insert" to "normal" mode in a timely fashion.
