b5305ce3d3 Handle backslashes properly in locate_brackets_of_type
This needs to be rewritten, I'm pretty sure we have like 6 of these
kinds of ad-hoc "is this quoted" things lying around.

But for now, at least don't just check if the *previous* character was
a backslash.

Fixes #7685.

e43913a547 Stop expanding globs in command position when performing error checking
Before running a command, or before importing a command from bash history,
we perform error checking. As part of error checking we expand commands
including variables and globs. If the glob is very large, like `/**`, then
we could hang expanding it.

One fix would be to limit the amount of expansion from the glob, but
instead let's just not expand command globs when performing error checking.

Fixes #7407

fbaa5d193d Declare functions in headers or use internal linkage (static)
Found with gcc's -Wmissing-declarations which gives warnings like

	../src/tinyexpr.cpp:61:5: warning: no previous declaration for ‘int get_arity(int)’ [-Wmissing-declarations]
	   61 | int get_arity(const int type) {

The same warnings show up for builtin functions like builtin_bg because they
currently don't include their own headers. I left that.
Also reformat the touched files.

cf075b4179 Teach up-line to cross empty lines
The line offset of a trailing newline on the commandline was computed incorrectly.
As a result, up-arrow did not work for a commandline like the one inserted by:

	commandline -i echo '' ''

Note this and the previous commit in the changelog.

f6c1ef58df Indent continuations after | and &&
This indents continuations after pipes and conjunctions if they contain
a newline.

Example:

    cmd1 &&
        cmd2

But it avoids the "double indent" if it indented unconditionally:

    cmd1 | begin
        cmd2
    end

More work towards improving #7252

0f7bba5f0e Introduce operation_context_t
This commit recognizes an existing pattern: many operations need some
combination of a set of variables, a way to detect cancellation, and
sometimes a parser. For example, tab completion needs a parser to execute
custom completions, the variable set, should cancel on SIGINT. Background
autosuggestions don't need a parser, but they do need the variables and
should cancel if the user types something new. Etc.

This introduces a new triple operation_context_t that wraps these concepts
up. This simplifies many method signatures and argument passing.

6fb7f9b6b8 Fix completion for builtins (with subcommands)
Presently the completion engine ignores builtins that are part of the
fish syntax. This can be a problem when completing a string that was
based on the output of `commandline -p`.  This changes completions to
treat these builtins like any other command.

This also disables generic (filename) completion inside comments and
after strings that do not tokenize.

Additionally, comments are stripped off the output of `commandline -p`.

f7dac82ed6 Escape separators (colon and equals) to improve completion
Fish completes parts of words split by the separators, so things like
`dd if=/dev/sd<TAB>` work.
This commit improves interactive completion if completion strings legitimately
contain '=' or ':'.  Consider this example where completion will suggest
a🅰️1 and other files in the cwd in addition to a:1

touch a:1; complete -C'ls a:'

This behavior remains unchanged, but this commit allows to quote or escape
separators, so that e.g. `ls "a:<TAB>` and `ls a\:<TAB>` successfully complete
the filename.

This also makes the completion insert those escapes automatically unless
already quoted.
So `ls a<TAB>` will give `ls a\:1`.

Both changes match bash's behavior.

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.
