Overhaul and simplify single_kboard API.  Allow calls to `recursive-edit' in process filters.  Small fixes.

* lisp/server.el (server-process-filter): Protect `display-splash-screen'
  call in a condition-case.  Explain why.

* src/callint.c (Fcall_interactively): Update call to
  `temporarily_switch_to_single_kboard'.

* src/fns.c (Fy_or_n_p): Ditto.

* src/frame.c (Fdelete_frame): Remove unused variable `count'.

* src/keyboard.c (wrong_kboard_jmpbuf): Remove global variable.

* src/keyboard.c (read_char): Add wrong_kboard_jmpbuf parameter to allow
  for recursive calls.  Update longjmp invocations.  Remember the
  original current_kboard, and longjmp to `wrong_kboard_jmpbuf' when a
  filter, timer or sentinel changes it.  Comment out unnecessary calls to
  `record_single_kboard_state' and `any_kboard_state'.  Update recursive
  calls.

* src/keyboard.c (read_key_sequence): Add `wrong_kboard_jmpbuf' local
  variable.  Update setjmp and read_char calls.  Abort if
  interrupted_kboard died in read_char.

* src/keyboard.c (any_kboard_state, single_kboard_state)
  (record_single_kboard_state): Comment out obsolete functions.
  (push_frame_kboard): Remove function.
  (pop_kboard): Switch out of single_kboard mode if the
  kboard has been deleted.
  (temporarily_switch_to_single_kboard): Change first
  parameter to a frame pointer.  Throw an error when caller wants to
  change kboards while in single_kboard mode.
  (restore_kboard_configuration): Abort if pop_kboard changed
  the kboard in single_kboard mode.
  (Frecursive_edit): Switch to single_kboard mode only in
  nested command loops.
  (cmd_error, command_loop, command_loop_1, timer_check):
  Comment out unnecessary call to `any_kboard_state' and
  `record_single_kboard_state'.

* src/keyboard.c (delete_kboard): Exit single_kboard mode if we have just
  deleted that kboard.

* src/keyboard.c (interrupt_signal): Use `Fkill_emacs' to exit Emacs, not
  `fatal_error_signal'.

* src/keyboard.h (read_char, single_kboard_state)
  (record_single_kboard_state): Remove.
  (temporarily_switch_to_single_kboard): Update.

* src/lread.c: Include setjmp.h.  Update declaration of `read_char'.
  (read_filtered_event): Call `read_char' with a local
  `wrong_kboard_jmpbuf'.

* src/minibuf.c (read_minibuf): Update call to
  `temporarily_switch_to_single_kboard'.

* src/termchar.h (tty_display_info): Rename `previous_terminal_frame'
  member to `previous_frame'.

* src/xdisp.c (redisplay_internal): Update references to
  `previous_terminal_frame'.
  (display_mode_line, Fformat_mode_line): Replace calls to
  `push_frame_kboard' with `push_kboard'.

before actually reading anything.  Handle all cases, including
START = END = nil and an already-narrowed buffer.
Convert END to a marker if it is a number.

(readevalloop): Compute ENTIRE properly.
(syms_of_lread) <load-history>: Doc fix.

Gcpro FOUND as well as FILE, but not EFOUND.
Unless preloading, record FOUND instead of FILE in Vload_history.
Rename repeat local FILE to MSG_FILE.

current buffer to read.  Callers changed.
When specified, narrow to this region only when reading,
not during eval.  Track next point to read from during eval.
Also restore point to "real" buffer position before eval.
(Feval_region): Don't save excursion and restriction here, and
don't narrow to region.  Just pass region to readevalloop.
Note: Point is now preserved even when PRINTFLAG is nil.
