fix buffer overflow when handling long composed input
To reproduce the issue:
"
If you already have the multi-key enabled on your system, then add this line
to your ~/.XCompose file:
[...]
<question> <T> <E> <S> <T> <question> :
"1234567890123456789012345678901234567890123456789012345678901234567890"
"
Reported by and an initial patch by Andy Gozas <andy@gozas.me>, thanks!
Adapted the patch, for now st (like dmenu) handles a fixed amount of composed
characters, or otherwise ignores it. This is done for simplicity sake.

Scrolling back and then entering keyboardselect's copy mode causes
glitched text to appear when moving the cursor. This is because the
keyboardselect patch is not aware of the scrollback history (term.hist),
so it takes the text from the last displayed screen (term.line).

This patch 1) improves reloading X resources - by considering fonts in
a way nearly identical to function `zoomabs`' - and 2) re-renders st so
that changed colors and fonts can be seen.
* fix externalpipein patch
don't close the slave fd, according to the original patch in
https://lists.suckless.org/hackers/2004/17218.html
* externalpipein patch: add example command
press S-C-M to set the terminal background green dynamically.
Replace `printf ...` with `dynamic-colors cycle` command mentioned in
https://lists.suckless.org/hackers/2004/17218.html to cycle though the
available dynamic color themes.
The openurlonclick and scrollback patches are now working together,
so links can be clicked in the scrollback buffer too. This update also
adds url underlining and other improvements to the openurlonclick patch.
The full list of changes in the openurlonclick patch:
- Adds scrollback support
- Adds modkey option
- Better url detection
- Underlines url when the mouse pointer is over a link
- Opens a browser as a background process, so it won't lock the terminal anymore
- Fixes a segmentation fault bug
the array is not accessed outside of base64dec() so it makes sense to
limit it's scope to the related function. the static-storage duration of
the array is kept intact.
this also removes unnecessary explicit zeroing from the start and end of
the array. anything that wasn't explicitly zero-ed will now be
implicitly zero-ed instead.
the validity of the new array can be easily confirmed via running this
trivial loop:
for (int i = 0; i < 255; ++i)
assert(base64_digits[i] == base64_digits_old[i]);
lastly, as pointed out by Roberto, the array needs to have 256 elements
in order to able access it as any unsigned char as an index; the
previous array had 255.
however, this array will only be accessed at indexes which are
isprint() || '=' (see `base64dec_getc()`), so reducing the size of the
array to the highest printable ascii char (127 AFAIK) + 1 might also be
a valid strategy.

This patch replaces the previous one I sent.
The following changes are made in this patch:
- Fix tracking of pressed buttons. Previously, pressing two buttons and
then releasing one would make st think no buttons are pressed, which
in particular broke MODE_MOUSEMOTION.
- Always send the lowest-numbered pressed button on motion events; when
no button is pressed for a motion event in MODE_MOUSEMANY, then send
a release. This matches the behaviour of xterm. (Previously, st sent
the most recently pressed button in the motion report.)
- Remove UB (?) access to potentially inactive struct member
e->xbutton.button of XEvent union.
- Fix (unlikely) possibility of overflow for large button numbers.
The one discrepancy I found between st and xterm is that xterm sometimes
encodes buttons with large numbers (>5) strangely. E.g., xterm reports
presses of buttons 8 and 9 as releases, whereas st properly (?) encodes
them as presses.
