aea7050efe Don't create a double stack frame when calling aliases
The old code created a new stack frame in parse_line_alias_special(), then
another one in parse_line().  This prevented $functioncall() from working,
and made the output of CALL look odd.

|Rain| mentioned this years ago in starman.irc.

8cc9684c76 Ensure close_server() clears the who/ison/userhost queues for the right server
close_server() should call clear_server_queues() on the server that's being
closed, not from_server.  This also lets us remove a few other calls to
clear_server_queues() that are right next to calls to close_server().

2520bd32f6 Separate parsing of channel WALLs into a function and clean it up
Channel WALL notices now have to match "[%Wall%/%] *", and have to be for
a channel that the client is actually on.  Otherwise, they just appear as
ordinary NOTICEs.

d1816fdc8b Don't mangle ANSI sequences in NOTICEs.
We pass through ANSI just fine in PRIVMSGs, so we might as well treat
NOTICEs the same way too.  The old code wasn't just stripping them out,
either - it was turning them into printable garbage.

75bd647d15 Switch stripansi() to stripansicodes() in the CTCP reply parser.
stripansi() actually just munged control-characters, so it just turned ANSI
codes into visible junk.

stripansicodes() instead leaves control characters alone but removes complete
ANSI sequences from the string.  I'm not sure if even that is necessary,
really - after all, we always allowed ^B, ^C etc style formatting in CTCP
replies.

498631e74a Introduce get_kick_reason() and switch all kick commands to use it
get_reason() is then used only for the implementation of get_kick_reason()
and for the $getreason() scripting function.  Add current nick as an
explicit argument for get_reason(), which pushes all use of from_server
out of the ransom reason functions.

Also switch a few instances of send_to_server() to my_send_to_server() where
the current server has been returned by prepare_command().

ff251080da Add get_kill_reason() that uses BitchX.kill, and convert all /KILL users to it
Previously only send_kill() used BitchX.kill - the other KILL commands (eg.
/WHOKILL) were using the random kick reasons.  Standardise them all on
BitchX.kill, and add this file to the source so it can be installed along
with the other random reason files.

27e32a0319 Cleanup and simplify get_reason() and related functions
Rename randreason() to fread_random() to better reflect its function,
and change it to a one-pass algorithm.  Have it write into a caller-provided
buffer instead of a static buffer.  Fixes a file leak when an empty
file is given to this function.

Change freadln() so that it never returns an empty line - it only returns
0 at end-of-file now.  This simplifies its callers.

Factor out some common code from the several get_reason()-type functions,
which greatly simplifies them.

ee0cd23ae5 Rearrange code in bankick() to silence a compiler warning
Re-checking the command name to see if it's a timed ban means that the
compiler can't see that it's the same check.

This also makes sure you can't specify a negative timeout.

05cf540a99 Fix use of uninitialised variable and hostmask matching logic in userhost_unban()
Initialise ip_str so that it isn't used uninitialised.

Don't strip server flags from user@ portion of the hostmask, so that it will
not miss matching bans.

Switch ip_str from alloca() to malloc_sprintf() / new_free() - there's no
particular need for alloca() here.

bc94fbe64a Remove a strange old piece of code apparently for detecting a server gone to lunch
This code appears to be some kind of backstop so that the client will notice
a server connection that's died because of a network interruption.  Checking
errno that was last set christ-knows-where is not the right way to do this,
though.

The normal write to the server for the lag check should eventually see the
host/net unreachable error if this happens.

1883e2c0c3 Minor fix to /STACK to make it match /SET behaviour
Previously /STACK would not accept just the initial part of a /SET name
even if it wasn't ambiguous.  Now it uses the same matching behaviour
as /SET.

This also removes an unused variable in do_stack_set().

6dbc712046 Rework and improve the scheduling of the server lag check
Previously the server lag check was run by update_clock() if the number of
seconds since client startup was a multiple of 20 (unless it had already been
done this second).  This meant that if update_clock() was not being called
frequently (eg. if your IRC connection was very quiet), it might go a long
time between lag checks.

This commit adds a /set LAG_CHECK_INTERVAL (defaulting to 30).  For each
server, a lag check ping is scheduled for every LAG_CHECK_INTERVAL seconds
after the connection is finalised/registered.  Setting this value to 0
disables the lag check pings entirely.

The old code set the lag to 'unknown' immediately after sending out a ping,
which meant that it was quite unpredictable how long the lag value would
stay around for.  The new code only sets this once the current lag value
has become stale (ie. a ping reply is overdue based on the current lag
value).  If your lag is staying the same or reducing, you shouldn't see
the [Lag ??] at all.

c0c7cdbdcc Rework the calculation of the select timeout in io() to be based on absolute wake time
An absolute wake time is now calculated and updated by set_server_bits(),
TimerTimeout() and tclTimerTimeout().  This is then used to calculate the actual
select() timeout, instead of having those functions calculate a relative timeout
value themselves.  This significantly simplifies those functions, since the
underlying values tend to be recorded as absolute times.

It also allows us to disentangle tclTimeTimeout from TimerTimeout(), and move the
responsibility for calculating the QUEUE_SENDS wake time from TimerTimeout() to
set_server_bits() where it belongs.

The QUEUE_SENDS and CONNECT_DELAY wake up times will also now be correctly
calculated, based on the last sent time and connect time respectively.

8cdc62ae0d Wire up /SET DOUBLE_STATUS_LINES so it actually does something
The DOUBLE_STATUS_LINES /SET has existed for a long while, but setting it has
never actually had an effect.  This change causes it to affect the
/window double setting of new windows: 0 means new windows are created without
double status lines, 1 means only the first window is created with double
status lines and subsequent windows aren't (this is the default) and 2 means
that all windows are created with double status lines.

Note that setting this variable in your .ircrc can't actually affect the first
window, because that's created before the .ircrc is loaded.  The compiled-in
default value (DEFAULT_DOUBLE_STATUS_LINES in config.h) is the only thing that
can affect the first window.

b14d0ddcb9 Add timer_cmp() utility function to compare two timevals.
This is preferable to using time_diff() to compare two timevals, because
time_diff() gives its result as a 'double' which only has 53 bits of
precision.

Also switch a couple of places from using time_diff() to using
this function.

f1c27a4f64 Switch server->connect_time from time_t to struct timeval
This means that settings like CONNECT_DELAY and CONNECT_TIMEOUT are compared
against the current time with sub-second resolution.  With the old way, the
delays could be up to a second longer than asked for, which had the effect of
almost doubling the default CONNECT_DELAY value of 1.
