Devin J. Pohly e0215d5377 Reduce visibility wherever possible
When possible, declare functions/variables static and move struct
definitions out of headers.  In order to allow utf8decode to become
internal, use codepoint for DECSCUSR extension directly.

Devin J. Pohly 30683c70ab Limit usage of extern to config.h globals
Prefer passing arguments to declaring external global variables.  The
only remaining usage of extern is for config.h variables which are
needed in st.c instead of x.c (where it is now included).

Devin J. Pohly a3beb626d2 Remove x.c dependency on term
The xinit function only needs to the rows/cols, so pass those in rather
than accessing term directly.  With a bit of arithmetic, we are able to
avoid the need for term.row and term.col in x2col, y2row, and
xdrawglyphfontspecs as well, completing the removal.

Term is now fully internal to st.c.

Devin J. Pohly a5dc1b4697 Pull term references out of xdrawcursor
Gradually reducing x.c dependency on Term object.  Old and new cursor
glyph/position are passed to xdrawcursor.  (There may be an opportunity
to refactor further if we can unify "clear old cursor" and "draw new
cursor" functionality.)

Devin J. Pohly 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)

Devin J. Pohly 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).

Devin J. Pohly 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.

Devin J. Pohly 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.

Devin J. Pohly 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

This commit is purely about reducing externs and LOC.  If the main and

eventually), these should come along with them.

Benno Fünfstück 1f24bde82b Fix color with FAINT attribute

Benno Fünfstück 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.

Nils Reuße 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.
