If the client program is drip feeding us input at a rate faster than 1
character per mux_output_parser_coalesce_delay_ms (e.g. it is printing
output read from a serial port faster than this), we would previously
wait indefinitely for new input, because we would always poll with a new
timeout [...]delay_ms in the future. In the worst case, this would create
a busy loop that starves the other panes of an opportunity to read from
their ptys, making all of them unresponsive. Address this by making a
note of when the first character was read, and do not wait longer than
[...]delay_ms after this time.
Fixes#3466.

mentioned that running `wezterm cli spawn --domain-name SSH:foo`,
closing that tab and running `wezterm cli spawn --domain-name SSH:foo`
again failed.
The error message had no useful context.
This commit adds more context.
macos doesn't have a num lock concept, so there is no num lock state
reported in modifiers. wezterm doesn't emulate that state because it
cannot guarantee to observe all key presses and correctly track it.
It's obvious that Nushell is intended to be skipped by default for close
confirmation. However, on Windows, Nushell instances are named `nu.exe`,
not `nu`, so they don't get skip-closed properly. Add `nu.exe` alongside
`nu`, so Windows behaves as expected.
We need access to the underlying raw/physical key in order
to correctly encode in some modes, so we need the full KeyEvent
struct for that.
Move the encoder up so it sits alongside the win32 input mode
encoder.
This should give us better results for both shifted/unshifted
and the "base layout" (US english) representations of a number
of keys.
Note that this is still not 100% technically correct: the unshifted
keys require knowledge of the keyboard layout that we don't have
at this OS-independent layer.
Right now we're assuming a US layout to unshift punctuation, which
is not right if you're not using that layout. To resolve that,
more work is needed on each OS to be able to extract that information
and then to store it in the KeyEvent.

We were missing encoding of these for the base xterm encoding
(I haven't daily driven a keyboard with a numpad in over 10 years!).
Improve mapping for the kitty protocol.

This commit teaches the termwiz layer about positional modifiers,
and expands our modifier concept to also pass through led states
such as caps lock and num lock.
Those aren't actually keyboard modifiers, but the state is useful
to recognize.
Adjust the shift key normalization so that we don't uppercase
alpha characters when both SHIFT and CAPS_LOCK are held.
This processing will remove both SHIFT and CAPS_LOCK in that
situation.
Add a method to KeyEvent that will undo the OS keyboard layer
normalization of positional to generic modifier key presses.
eg: the OS may map LeftControl -> Control, but we actually
prefer to have LeftControl so if we can unambiguously reverse
that mapping, we do so.
