SD sequence (`${CSI}${N}T`) was scrolling the whole width
of the terminal instead of just between the margins.
RI sequence (`${ESC}M`, move cursor up 1 line) was doing the same.
Fixed that.
Fixes#2576 where in tmux scrolling one of several
side-by-side panels down resulted in all visually scrolling.
Implement the following CSI escape sequences from
https://invisible-island.net/xterm/ctlseqs/ctlseqs.html:
> CSI Ps ; Ps ; Ps t
> [..]
> Ps = 1 4 ⇒ Report xterm text area size in pixels.
> Result is CSI 4 ; height ; width t
> [..]
> Ps = 1 6 ⇒ Report xterm character cell size in pixels.
> Result is CSI 6 ; height ; width t
Extracted from changes in https://github.com/termux/termux-app/pull/2973
by @MatanZ and adopted to play well with the just merged #3098 (.ws_xpixel
and .ws_ypixel values in winsize).
This allows to get terminal size in pixel using `TIOCGWINSZ` ioctl.
Set `.ws_xpixel` using `columns * cell_width` and set `.ws_ypixel` using `rows * cell_height`.
Cell width and height is font width and line spacing, respectively.
- The AutoFill type and hints are no longer hardcoded in `TerminalView` class and `TermuxActivity` layout xml. They are dynamically set to required values before making a manual AutoFill request and reverted back afterwards to default values. The hardcoded value `AUTOFILL_TYPE_TEXT` returned by `getAutofillType()` was causing the AutoFill UI to show on Activity starts, this will return `AUTOFILL_TYPE_NONE` by default now so that AutoFill UI isn't shown automatically.
- The AutoFill importance is no longer hardcoded in `TermuxActivity` layout xml and is returned by `TerminalView` class itself by `getImportantForAutofill()`.
- The AutoFill function in `TermuxActivity` for making a manual AutoFill request is moved to `TerminalView` class. This and moving of hardcoded values to `TerminalView` class mentioned above is done as complete logic of AutoFill should be handled by `TerminalView` class itself and not scattered in various places.
- The Terminal context menu now supports AutoFilling a username. Note that GBoard/Google Password Manager seems to have a bug where it will still show `Pick a saved password` instead of username, even though `AUTOFILL_HINT_USERNAME` is being requested, however it will still AutoFill a username of selected entry correctly.
- Pressing the back button to close the keyboard will also cancel the current manually requested AutoFill request and UI will not show when keyboard is opened again.
Closes#3909
In other terminals, such as gnome-terminal, Shift-PgUp and Shift-PgDn
scroll the screen by a full page, rather than a single line. Adjust
termux to match.
Currently the Termux terminal emulator prints "HI" in red with:
```sh
printf "\e[31;m HI \e[0m"
```
This is not how other terminals (tested on xterm, gnome-terminal,
alacritty and the mac built in terminal) handle it, since they parse
""\e[31;m" as "\e[31;0m", where the "0" resets the colors.
This change aligns with other terminals, as well as improves performance
by avoiding allocating a new int[] array for each byte processed by
`parseArg()`, and most importantly simplifies things by removing the
`mIsCSIStart` and `mLastCSIArg` state, preparing for supporting ':'
separated sub parameters such as used in

Do not use `upload-release-action` for uploading artifacts and generating checksum and instead keep using standard `sha256sum` and internal github tools. `upload-release-action` also generates checksum in the wrong format, check https://github.com/termux/termux-app/pull/3241#discussion_r1106019790.
The exception below causing app crash happens because of malicious input where combining characters keep getting added to same column of the row and this increases the size of `mSpaceUsed` and `mText`, eventually causing a buffer overflow of `mSpaceUsed`, which is limited to max `32767` value as per java `short` limit, but the limit itself isn't the issue, but an endless number of combining characters being added. Check `MAX_COMBINING_CHARACTERS_PER_COLUMN` field javadocs for why the limit `15` was chosen.

See also following links for history of related changes to `TerminalRow` for combining characters. Note that jackpal terminal does not crash for above, which termux-app is based on, but changes were done by fornwall in initial commit of termux-app to change the behaviour, hence the crash, but he added the `FIXME: Put a limit of combining characters` comment as a note to solve the current issue in future, which is now.

The `Docs` refer to "something" that is changed, and not the type of change being made. If docs are to be changed in future, it should be added as a scope instead, like `Added(docs): Add some docs` or `Fixed(docs): Fix some docs`.
Presence of phantom process killer on Android 12 doesn't mean Termux is
broken. It could be unstable because of abrupt termination of all
processes by signal 9 under certain cases. But this doesn't mean it is
unusable on all devices with Android 12 or higher.
The word "broken" could be too scary for new users.
This will work for both `SHIFT` extra key and hardware keyboards. The `SHIFT` extra key can be long held to lock it in an enabled state and `PGUP` and `PGDN` keys can be long held to repeat scrolling.
Closes#867
