3eb170a9a5 Add scrollback support to the openurlonclick patch
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

d8ec7a396c base64_digits: reduce scope, implicit zero, +1 size
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.

5bf86e1ca2 Fix mousereport
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.

b5d7194d90 Fix overtyping wide characters.
Overtyping the first half of a wide character with the
second half of a wide character results in display garbage.
This is because the trailing dummy is not cleaned up.

i.e.  ATTR_WIDE, ATTR_WDUMMY, ATTR_WDUMMY

Here is a short script for demonstrating the behavior:

	#!/bin/sh
	alias printf=/usr/bin/printf
	printf こんにちは!; sleep 2
	printf '\x1b[5D'; sleep 2
	printf へ; sleep 2
	printf ' '; sleep 2
	echo

c02ad97409 fix possible rare crash when Xutf8TextPropertyToTextList fails
from the XmbTextListToTextProperty(3) man page:

"If insufficient memory is available for the new value string, the functions
return XNoMemory.  If the current locale is not supported, the functions return
XLocaleNotSupported.  In both of these error cases, the functions do not set
text_prop_return."

78adbd2406 fix a problem that the standard streams are unexpectedly closed
In the current implementation, the slave PTY (assigned to the variable
`s') is always closed after duplicating it to file descriptors of
standard streams (0, 1, and 2). However, when the allocated slave PTY
`s' is already one of 0, 1, or 2, this causes unexpected closing of a
standard stream. The same problem occurs when the file descriptor of
the master PTY (the variable `m') is one of 0, 1, or 2.

In this patch, the original master PTY (m) is closed before it would
be overwritten by duplicated slave PTYs. The original slave PTY (s)
is closed only when it is not one of the standarad streams.

5452c4f4d3 Removing 't' case for SIXEL patch ref. #35.
#if SIXEL_PATCH
	case 't':
		/* TODO should probably not be hard-coded */
		ttywrite(";420;720t", 10, 1);
		break;
	#endif // SIXEL_PATCH

This would result in printing ";420;720t" when exiting neovim.

Without this code a line is written to standard err instead:

erresc: unknown csi ESC[23;0t

The ttywrite was added as part of this commit:
   - b50be8225d

which states:

> When a S or T CSI escape was encountered, the lines which were scrolled
> away would be deleted from the scrollback buffer. This has been
> corrected - the lines are now preseved.
>
> This fixes a bug where issuing `clear` followed by `lsix` would cause
> the line on which the `lsix` was issued to disappear from the scrollback
> buffer.
>
> Note that the line may scroll out of view and thus dissapear, but it
> will now be preserved in the scrollback buffer.

Given that we could not reproduce the above bug without the ttywrite in
this case I am not convinced that this is actually needed. Leaving this
here in case this comes up again in the future.
