Rename "initial" state to "telopt_negotiation"
There was a rare race where if a client disconnected during the
initial Telnet option negotiation pause, an attempt to log an entry
about it would raise an exception because the "initial" state
placeholder in the default menu data was incorrectly-named. Fix
that, and rename the state to "telopt_negotiation" so it's less
confusing to debug if similar issues are discovered with this state
in the future.

Test that ANSI input is filtered
Add a simple regression test to make sure ANSI escape sequences
aren't allowed in input lines. The escape (byte \x1b) character
should be filtered from non-binary-mode clients because we filter to
a "printable" set. For binary-mode clients an escape won't be valid
UTF-8 and so will cause the entire line of input on which it's found
to be skipped.

Only wrap on actual spaces
Trying to match on Unicode character classes to determine where to
wrap lines turns out to be a fragile and blacklist-heavy exercise.
Instead, just wrap on actual (ASCII \x20) space characters. This
fixes a bug where the escape characters starting ANSI sequences were
sometimes matching as a wrap point garbling the output, but also
simplifies the code by no longer needing to exclude carriage returns
in a CR+LF line ending sequence. Further it solves a couple TODO
reminders to stop wrapping on non-breaking (Unicode \xa0) space
characters.

Filter non-ASCII input when not in binary mode
If the client does not have binary send enabled per prior Telnet
option negotiation, filter for non-ASCII characters. This fixes a
bug where previously only binary mode senders were checked for
non-ASCII input and 7-bit senders were checked for non-UTF-8 input
rather than the other way around.

Retool word wrapping
Better handle CR+LF injection when encountering words longer than
the terminal width. If a word is so wide it cannot be wrapped, leave
it on a line by itself and allow the terminal to apply its own
wrapping rules instead. Fixes a bug where excessive EOL markers
would get added in such situations. Also more accurately handles
skipping ANSI escape sequences in subsequently wrapped content.
Include a word-wrapping test in the selftests to avoid regressing
here.
