88d8293fb4 Move win-agnostic parts of draw/drawregion to st.c
Introduces three functions to encapsulate X-specific behavior:
 * xdrawline: draws a portion of a single line (used by drawregion)
 * xbegindraw: called to prepare for drawing (will be useful for e.g.
   Wayland) and returns true if drawing should happen
 * xfinishdraw: called to finish drawing (used by draw)

05c66cb37d Split mode bits between Term and TermWindow
Moves the mode bits used by x.c from Term to TermWindow, absorbing
UI/input-related mode bits (visible/focused/numlock) along the way.

This is gradually reducing external references to Term.  Since
TermWindow is already internal to x.c, we add xsetmode() to allow st to
modify window bits in accordance with escape sequences.

IS_SET() is redefined accordingly (term.mode in st.c, win.mode in x.c).

33201ac65f Move CRLF input processing into ttywrite
This also allows us to remove the crlf field from the Key struct, since
the only difference it made was converting "\r" to "\r\n" (which is now
done automatically in ttywrite).  In addition, MODE_CRLF is no longer
referenced from x.c.

The only thing differentiating ttywrite and ttysend was the potential
for echo; make this a parameter and remove ttysend.

cfc7acdfd9 Move remaining selection mode logic into selextend
The "done" parameter indicates a change which finalizes the selection
(e.g. a mouse button release as opposed to motion).

bcb5d3adbe Move terminal-related selection logic into st.c
The front-end determines information about mouse clicks and motion, and
the terminal handles the actual selection start/extend/dirty logic by
row and column.

While we're in the neighborhood, we'll also rename getbuttoninfo() to
mousesel() which is, at least, less wrong.

d84f3f4bd1 Rely on ttyresize to set tty size
This removes ttynew's dependency on cresize being called first, and then
allows us to absorb the ttyresize call into cresize (which always

32d3b1d00f Factor out equivalent code from ttyread/ttysend
The echo-to-terminal portions of ttyread and ttysend were actually doing
the same thing.  New function twrite() now handles this.  The parameter
show_ctrl determines whether control characters are shown as "^A".  This
was the only difference between tputc and techo, and techo is now unused
and removed.

(This commit should not change st's behaviour.)

e829e13bb1 Apply ATTR_REVERSE after ATTR_FAINT
An example where the new behaviour makes more sense:

Suppose some text is formatted with ATTR_FAINT for red for the foreground, so it
is rendered in a dark red. In that case, when selected with the mouse, the
intended behaviour is that foreground and background color are swapped: so the
selection should be rendered in dark red and the text in the default background
color.

Before this patch, what happened was that the selection would be in normal red
and the text in the darkened background color, making it almost unreadable.

For an example application that uses the FAINT attribute, try dmesg from
util-linux with color support, it uses FAINT for segfault messages.

ee5cc8e903 base64dec: skip non-printable characters like \r\n
Non-printable characters, such as line breaks, in a base64 encoded
string violate the "string length must be a multiple of four" rule.

This patch pads the result buffer by one extra unit of four bytes,
and skips over non-printable characters found in the input string.

f2bfd513b1 keep some glyph modes for the cursor
st currently does not keep any mode for the cursor that was active
in the underlying glyph (e.g. italic text), the mode is always
ATTR_NULL [1].  At [2] you can find a screenshot that shows the
implications.  Other terminals (at least vte-based, such as
XFCE-terminal) keep some modes for the cursor.  I find the current
behaviour very disruptive, so here is a patch that keeps a few
(arbitrarily chosen) modes for the cursor.

20f713548d Change default keybindings
CTRL+SHIFT is an impossible combination in the terminal world
(0x20 | x & 0x1F), so it is perfect to be used for internals
shortcuts of terminals, and being a double combination
reduces the prossibility of having comflicts.
