65749f06a3 mux: fix poll interval. show update indicator
Add an update indicator to the top right of client tabs; this is
overlaid on top of the surface when the last update from the server was
more than ~3s ago and if we expected it sooner than that.

While making this work, I noticed that the exponential poll backoff
had gotten broken in an earlier refactor; instead of a series of polls
backing off slowly, we were aggressively running the backoff up to the
max 30 second interval over the span of a few ms.   This commit fixes
up the backoff computation to only happen when we are ready to send
a poll.

ca2e9c013a termwiz: do not depend on derive_builder
derive_builder has some extra dependencies that take a while to compile.
The builder feature can be expressed via a 30-line macro. So let's do
that to make termwiz compile faster.

f51650c891 termwiz: remove dep on palette
The palette crate has a codegen step that translates svg_colors.txt to named.rs.
That makes it hard to build using buck.

Remove the palette dependency so termwiz is easier to build using buck.

I made sure the following code:

    fn main() {
        use termwiz::color::RgbColor;
        let r = RgbColor::from_rgb_str("#02abcd").unwrap();
        let r1 = r.to_tuple_rgba();
        let r2 = r.to_linear_tuple_rgba();
        println!("r1 = {:?}", r1);
        println!("r2 = {:?}", r2);
    }

prints

    r1 = (0.007843138, 0.67058825, 0.8039216, 1.0)
    r2 = (0.000607054, 0.4072403, 0.6104956, 1.0)

before and after the change.

e6b4aa835a re-wrap lines when resizing
Adds logic to resize handling that will consider the original logical
line length when the width of the terminal is changed.

The intent is that this will cause the text to be re-flowed as if it had
been printed into the terminal at the new width.  Lines that were
wrapped due to hittin the margin will be un-wrapped and made into a
single logical line, and then split into chunks of the new width.

This can cause new lines to be generated in the scrollback when
making the terminal narrower.  To avoid losing the top of the buffer
in that case, the rewrapping logic will prune blank lines off the
bottom.

This is a pretty simplistic brute force algorithm: each of the lines
will be visited and split, and for large scrollback buffers this could
be relatively costly with a busy live resize.  We don't have much choice
in the current implementation.

6fdae9b226 Make UnixTerminalWaker::wake non-blocking
I was running `hg log --config pager.pager=sp` and pressing space without
releasing it. After about 10k lines sp appears to deadlock. It seems sp uses a
single thread for both reading terminal events and sending wake events and it
sends too many wake events without reading the events.

Failing to write to the wake pipe due to EWOULDBLOCK does not seem to be a
problem - there are enough events in the pipe to wake up the other side.
Therefore let's just make wake_pipe_write nonblocking and treat EWOULDBLOCK as
a success.

Context: The stuck thread looks like:

7c7825c070 term: extract configuration to a trait
This isn't complete but begins the process of extracting
the embedding application configuration into a trait provided
by the application rather than passing the values in at
construction.

This allows the application to change configuration at

The first option to handle this is the scrollback size.

6da7b3ecd0 internalized password/auth UI for ssh
This is a bit of a large commit because it needed some plumbing:

* Change mux creation to allow deferring associating any domains,
  and to change the default domain later in the lifetime of the
  program
* De-bounce the empty mux detection to allow for transient windows
  during early startup
* Implement a bridge between the termwiz client Surface and the
  frontend gui renderer so that we can render from termwiz to
  the gui.
* Adjust the line editor logic so that the highlight_line method
  can change the length of the output.  This enables replacing
  the input text with placeholders so that we can obscure password
  input

1ab438c1e2 improve emoji width calculation
I noticed while scrolling `emoji-test.txt` that some of the combined
emoji sequences rendered very poorly.  This was due to the unicode
width being reported as up to 4 in some cases.

Digging into it, I discovered that the unicode width crate uses a
standard calculation that doesn't take emoji combination sequences
into account (see https://github.com/unicode-rs/unicode-width/issues/4).

This commit takes a dep on the xi-unicode crate as a lightweight way
to gain access to emoji tables and test whether a given grapheme is
part of a combining sequence of emoji.

23b4876d75 fix an issue with utf-8 in OSC sequences
I've noticed this off and on for a while, and thought it was something
fishy with my shell dotfiles.

Tracing through I found that the final byte in the "Face with head
bandage" emoji 🤕 U+1F915 was being interpreted as the MW control
code and causing the vt parser to jump out of the OSC state.

The solution for this is to hook up proper UTF-8 processing in the
same way that it is applied in the ground state.

Since we don't have enough bits to introduce new state values (we're
pretty tightly packed in the 16 bits available), I've introduced a
memory of the state to which the utf8 parser needs to return once
a complete sequence is detected.
