We should be treating the end of data the same way we treat a newline.
A common issue that affects a good number of plugins is that we don't deal with
trailing space well. For example, most plugins that respond with a large list of
values, where we iterate over an array or list, or something else, they usually
end up responding with a trailing space before the newline.
If we feed that same string back as an update, we can end up in a situation
where we lock up (or become very, very slow), because we want to read more data
than is available. Why? Because `Serial.parseInt()` (used by Focus under the
hood) will swallow up any leading whitespace. So if we have "255 \n" as an
argument list, we'll parse the first number, and the second `parseInt()` will
return 0, because it times out waiting for a number, consuming both the space
and the newline in the process. Thus, the next `::isEOL()` will still return
false, because `peek()` returns `-1`, signaling no data.
That can confuse the heck out of our plugins. To combat that, we should treat
end of data the same as EOL, and return false if `peek()` returns -1, too.

This is the result of running the `include-what-you-use` wrapper, followed by
the `clang-format` wrapper on the Kaleidoscope codebase. It is now safe to use
both without needed any manual corrections after the fact, but it's still
necessary to run clang-format after IWYU, because the two differ in the way they
indent comments after header files.

Tested to work on both a Model 01 and a Model 100. This will become
unnecessary when the GD32 Arduino core grows the ability to autoflush on
SOF packets from the host
This standardizes namespace closing brackets for namespace blocks. Each one is
on its own line, with a comment clearly marking which namespace it closes.
Consecutive lines closing namespace blocks have no whitespace between them, but
there is one blank line before and after a set of namespace block closing lines.
To generate the namespace comments, I used clang-format, with
`FixNamespaceComments: true`. But since clang-format can't exactly duplicate
our astyle formatting, it made lots of other changes, too. To isolate the
namespace comments from the other formatting changes, I first ran clang-format
with `FixNamespaceComments: false`, committed those changes, then ran it again
to generate the namespace comments. Then I stashed the namespace comments,
reset `HEAD` to remove the other changes, applied the stashed namespace
comments, and committed the results (after examining them and making a few minor
adjustments by hand).

To make it easier - or in some cases, even possible - to put the keyboard into
programmable mode, we need to be able to initiate a reset from the host side.
For example, ynlike on AVR, where we can send a HUP to the serial port, on GD32,
we need to do it a bit differently: by sending the keyboard a Focus request to
reboot itself.
This implements the command itself.

This implements a new `FocusSerial` command: `plugins`. The `plugins` command
will reply back with a list of plugins enabled in the firmware. The list is not
exhaustive, only plugins that opt-in to this mechanism will be listed. It is
opt-in, because for a lot of plugins, having them listed isn't useful in a
practical sense.
The goal with this feature is to allow Chrysalis to detect plugins that would
affect what keys it offers, or which additional settings it displays, and do so
in a consistent way. This is why IdleLEDs has an `onNameQuery` handler too, even
though it can be detected otherwise: for consistency.
