catgirl correctly handles receiving "self-messages". pounce always
sends them.

This fixes the case where an IRCd does not normalize channel names,
e.g. PRIVMSG #TEST is relayed as-is, rather than as #test or whatever
the canonical casing of the channel name is. It also fixes the case
of opening a query window with incorrect case, e.g. /query nickserv.
However, this solution is only completely correct when
CASEMAPPING=ascii.[1] I do not think the extra mappings of
CASEMAPPING=rfc1459 are relevant enough to justify adding the code
to handle it.

Silencing all windows with `M-+' (across multiple catgirl instances)
can be cumbersome, so provide an option to hide events, JOIN/PART noise,
etc. by default (each window's threshold will persist across load/save
cycles, i.e. when using the `-s/save' option).
Started out as `-v | visibility = threshold' to set a specific level,
the idea of a simpler toggle comes from june, who also squashed other
bugs (as usual).

ircConnect() yields a connected TCP socket after which "inet dns" is
no longer needed.
Possibly having loaded private key material, it seems a tad more
comforting to speak TLS *after* dropping any network capabilities
(except for socket read/write to the IRC host, of course).
Instead of moving the final pledge into irc.c:ircConnect() and thus
complicating the code around pledge across two C modules, simply
stub out an mnemonic ircHandshake() and call that explicitly.
This restores behaviour gained with
981ebc4 "Remove explicit tls_handshake(3) from ircConnect" which
was reverted for other reasons.

dataMkdir() already picked the appropiate directory so make it
return that such that unveilData() can go as only that one directory
needs unveiling.

This could just iterate over idNames instead, but using complete
means more recently used windows will match first.

Opening the same file *path* twice is a TOCTOU, although not a critical
one: worst case we load from one file and save to another - the impact
depends on how and when catgirl is started the next anyway.
More importantly, keeping the file handle open at runtime allows us to
drop all filesystem related promises for `-s/save' on OpenBSD.
uiLoad() now opens "r+", meaning "Open for reading and writing." up
front so uiSave() can write to it. In the case of a nonexistent save
file, it now opens with "w" meaning "Open for writing. The file is
created if it does not exist.", i.e. the same write/create semantics as
"w" except uiLoad() no longer truncates. existing files.
uiSave() now truncates the save file to avoid appending in general.

It is technically undefined behavior (see C11 6.5.6p8) to construct
a pointer more than one past the end of an array. To prevent this,
compare n with the remaining space in the array before adding to
ptr.

Based on seprint(2) from Plan 9. I'm not sure if my return value
exactly matches Plan 9's in the case of truncation. seprint(2) is
described only as returning a pointer to the terminating '\0', but
if it does so even in the case of truncation, it is awkward for the
caller to detect. This implementation returns end in the truncation
case, so that (ptr == end) indicates truncation.

Reuse the /window command to preserve /wi abbreviation.

|
So that the first part of $SSH_CLIENT can be passed as username.

Using the +draft/reply client tag, which is supported by BitBot.
This hides the bot's replies to ignored users or ignored bot command
messages.
This commit is dedicated to the land of Estonia.

This feature is rarely used, so just skip STATUSMSG prefixes in the
target so messages get routed correctly.

This restores showing the topic and names for automatic joined
channels, while still avoiding touching the windows, by using Cold
heat.
|
|
This allows for non-ASCII characters in timestamps, and simplifies
things by including the trailing space in the width.

This directly correlates hard-wrapped lines with the soft lines
they were wrapped from.
Choosing uint here because it doesn't change the size of struct
Line. It doesn't at all matter since buffers only hold 1024 lines
at a time anyway.

Restrict mode will focus on sandboxing, while kiosk will continue
to restrict IRC access through a public kiosk. Kiosk mode without
restrict mode allows execution of man 1 catgirl with /help, assuming
external sandboxing.
The /list and /part commands are also added to the list of disabled
commands in kiosk mode, since they are pointless without access to
/join.

This allows limiting the nick colors used to the 16-color terminal set
without modifying the TERM environment variable. Produces different
results from just using the default configuration in a 16-color
terminal, but what can you do?

Split ignore fields and match each separately to avoid an early *
eagerly matching across several fields. For example, "* JOIN * *" should
not match messages which happen to contain the word "JOIN" followed by
two other words.
Ignore capacity is reduced to 64 to keep the size of the array the same.
I don't think it's an issue.

I'm not sure about that replies check in handleStandardReply. If more of
those are added the reply counter system will definitely need
refactoring.
|
|
Split UI initialization into two steps either side of the call to
connect, so that C-c works as interrupt while it's blocked.

While the automatic search via LESS is neat, I don't think it's very
useful. Just always open the manual to the COMMANDS section, and fix it
to append to LESS rather than replace it.

Accumulate names in a buffer and show away status.
|
|
It's pretty awkward with large channels since NAMES isn't sorted by
prefixes or anything... But having it accumulate names across many
replies would require more reworking.

This restores normal scrolling behaviour.
|
|
So they can be preserved forever!
|
|
Still missing: split scrolling and preserving a blank on reflow either
from resize or ignore toggling.
Anecdata: on one of my instances of catgirl, RAM usage of the previous
release was ~30M, RAM usage of this commit was ~12M.

Not yet rendered in the UI! Just done in parallel.
|

In preparation for doing line wrapping outside of ncurses.
