The "HILIGHT_REC" structure used to keep a pointer to the "servertag"
string, owned by the "CONFIG_NODE", causing a double-free.

it is possible to delete the current history entry using the
erase_history_entry key binding
|
|
it is possible to use Irssi::UI::Window::get_history_entries to save the
history entries, load_history_entries to load entries into the command
history and delete_history_entries to remove history entries (for example
to remove history selectively)
|
|
this allows access to the global history even when a using /window history
named or /set window_history on, and you want to recall something from one
of the other windows' histories.
usage (default): ctrl+up/down

Originally found by oss-fuzz (issue 525) in get_ansi_color using ubsan.
After a lot of analysis I'm 99% sure this isn't security relevant so
it's fine to handle this publicly.
The fix is mainly adding a function that does it right and use it
everywhere. This is harder than it seems because the strtol() family of
functions doesn't have the friendliest of interfaces.
Aside from get_ansi_color(), there were other pieces of code that used
the same (out*10+(*in-'0')) pattern, like the parse_size() and
parse_time_interval() functions, which are mostly used for settings.
Those are interesting cases, since they multiply the parsed number
(resulting in more overflows) and they write to a signed integer
parameter (which can accidentally make the uints negative without UB)
Thanks to Pascal Cuoq for enlightening me about the undefined behavior
of parse_size (and, in particular, the implementation-defined behavior
of one of the WIP versions of this commit, where something like signed
integer overflow happened, but it was legal). Also for writing
tis-interpreter, which is better than ubsan to verify these things.

Don't allow command history to wrap around
|
|
Allows syntax info to be picked up and displayed by help command.
Fixes #687
|
|
We are no longer using over_counter for any functional purpose, so
remove it.
|
|
This changes the behavior of the command history to avoid wrapping back
to the bottom once the top of the history is reached.
|
|
If text is being entered and then the user presses the up arrow
followed by the down arrow, the expected behavior is to return to the
text being entered. Prior to this commit that was not the case.
Fixes #462
