June McEnroe 70f627bc47 Enable -Wmissing-prototypes
In other words, warn when a function is missing static. I don't see
why this isn't in -Wextra.

June McEnroe 1a2477ef7a Implement new line editing "library"
Losing tab complete and text macros, for now.

This new implementation works on an instance of a struct and does
not interact with the rest of catgirl, making it possible to copy
into another project. Unlike existing line editing libraries, this
one is entirely abstract and can be rendered externally.

My goal with this library is to be able to implement vi mode. Since
it operates on struct instances rather than globals, it might also
be possible to give catgirl separate line editing buffers for each
window, which would be a nice UX improvement.

June McEnroe 573bc855a6 Simplify cursor positioning in input
Do some extra work by adding the portion before the cursor to the
input window twice, but simplify the interaction with the split
point. This fixes the awkward behaviour when moving the cursor
across colour codes where the code would be partially interpreted
up to the cursor.

Woops! BASE64_SIZE is the size of the string buffer. Somehow ergo

Alyssa Ross 431230e0ea Support custom pkg-config executable names
When cross-compiling, it's common to have executables prefixed with
the name of the architecture you're building for,
e.g. aarch64-unknown-linux-musl-cc or x86_64-unknown-freebsd-pkg-config.
Lots of build tools support a PKG_CONFIG environment variable to
enable this use case.

With this change, I was able to successfully cross-compile and run
catgirl.

C. McEnroe 9c1b241c17 Cycle between adding colon suffix and not in tab complete
Allows completing a nick at the beginning of a message without a
colon by continuing to press tab, as well as after another nick
already followed by a colon without turning it into a comma-separated
list of nicks all followed by a colon. For example, tab can be used
to cycle between the following pairs:

    nick1: |
	nick1 |

	nick1, nick2: |
	nick1: nick2 |

C. McEnroe 4363d4b535 Parse IRC formatting in timestamp string
Strip formatting when calculating the timestamp width to avoid
moving a bunch of code around. Use styleAdd (now with an initial
style parameter) to show timestamps.

This allows changing the style of the timestamps from the default
gray using literal IRC formatting codes in the string. Not ideal,
but no new options needed.

Suggested by Hoël Bézier and Sebastian LaVine.

psykose 27b5fd0251 Fix strptime decode for musl libc
POSIX does not define a %F for strptime[1], but does define %F for
strftime[2]. Afaik most libc's implement %F for both, but musl is very
standards-compliant and does not have %F on strptime, leading to
unparsed message tag times, which causes all backlog sent from bouncer
on startup to have a timestamp of the current time, instead of the
actual timestamp sent.

C. McEnroe be9bffdf49 Match id names case-insensitively
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.

C. McEnroe d9388fa2a8 FreeBSD: Revert caph_enter(3) call to cap_enter(2)
caph_enter(3) is the same as cap_enter(2) except that it returns
success even if the kernel does not support capability mode. Since
we only enter capability mode when explicitly requested by the
restrict option, it should fail loudly if it is not supported. On
the other hand, we make calls to caph_rights_limit(3) and friends
in some places regardless of whether we actually enter capability
mode (to keep the code simple), so those should continue to succeed
even if capability mode is not supported.

C. McEnroe 347e2b461f Don't apply uiThreshold to Network and Debug
Messages don't really need to be hidden from <network> and I think
it could be confusing. Debug messages are all Cold so everything

doesn't clutter the status line needlessly.

Klemens Nanni f8e3414af0 Add -q/quiet option to raise default message visibility threshold
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).

Klemens Nanni ae332f6e8d Perform TLS handshake after final pledge
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.

Klemens Nanni ae64d277b8 Explicitly clear TLS secrets afer handshake
No need to keep them at runtime;  do so unconditionally for the sake of
simplicity.

Declare TLS config globally so ircConnect() can clear it and declare
both client and config statically as they are not used outside the irc.c
module.

Klemens Nanni 40b3f52aaf Revert "Remove explicit tls_handshake(3) from ircConnect"
This reverts commit 981ebc4f12.

This broke `-o' to print the server certificate;  without explicit
handshake there will be no tls_read(3) in this short code path.
