* src/marker.c: Try and speed up byte<->char conversion with many markers.
When considering markers (to find a starting point for the conversion),
typically one of the two bounds is nearby (coming from
cached_(byte|char)pos) but the other is far (point-min or point-max),
so change the exit condition so we stop as soon as *one* of the bounds
is near.
(BYTECHAR_DISTANCE_INITIAL, BYTECHAR_DISTANCE_INCREMENT): New constants.
(buf_charpos_to_bytepos, buf_bytepos_to_charpos): Use them to try and
reduce the number of markers we consider.
