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)

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).

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

The "done" parameter indicates a change which finalizes the selection
(e.g. a mouse button release as opposed to motion).

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.

There was only a single reference to the `win` variable in st.c, so
exporting that to x.c allows us to rid ourselves of another extern.

config.h includes references to KeySyms and other X stuff. Until we
come up with a cleaner way to separate configuration, it is simpler
(leads to more code removal) to have this here.

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.)

This commit is purely about reducing externs and LOC. If the main and
run functions ever move elsewhere (which will probably make sense
eventually), these should come along with them.

Modifiers and keysyms are specific to X, and the functions match and
kmap are only used in x.c. Needed to global-ize the key arrays and
lengths from config.h (for now).

This makes x(un)loadfonts internal to x.c. Needed to reorder includes
and move a typedef to keep the compiler happy.
