width/height elements of click events.
(Accessing Events): Add posn-string, posn-image, and
posn-object-width-height. Change posn-object to return either
image or string object.
(posn-string, posn-image): New defuns.
(posn-object): Return either image or string object.
(posn-object-x-y): Return 8th element of position.
(posn-object-width-height): New defun.
buffer_posn_from_coords, and marginal_area_string functions to
include both string object and image object in the lispy position.
Also add actual glyph width and height to position.
(read_key_sequence): Use real buffer position from mouse
event to find keymap property even when click is in marginal area.
(What Is a Function): `functionp' returns nil for macros. Clarify
behavior of this and following functions for symbol arguments.
(Function Documentation): Add `\' in front of (fn @var{arglist}) and
explain why.
(Defining Functions): Mention DOCSTRING argument to `defalias'. Add anchor.
(Mapping Functions): Add anchor. Unquote nil in mapcar* example.

(READ_OUTPUT_DELAY_INCREMENT, READ_OUTPUT_DELAY_MAX)
(READ_OUTPUT_DELAY_MAX_MAX): New constants.
(process_output_delay_count, process_output_skip): New vars.
(Vprocess_adaptive_read_buffering): New variable.
(make_process): Initialize adaptive read buffering members.
(Fstart_process): Set adaptive_read_buffering member.
(deactivate_process): Cleanup adaptive read buffering.
(wait_reading_process_input): Temporarily omit delayed
subprocesses from the set of file descriptors to read from;
adjust the select timeout if we skipped any subprocesses.
(read_process_output): Increase adaptive read buffering delay if
we read less than a full buffer; reduce delay when we read a
full buffer.
(send_process): Simplify using local Lisp_Process var.
Reset adaptive read buffering delay after write.
(init_process): Initialize process_output_delay_count and
process_output_skip.
