maint: Clean up m-files before Octave 8.1 release.
* external.txi, oop.txi, Table.h, documentation.cc, gui-preferences-ed.h,
lo-specfun.cc, range.tst : Eliminate triple newlines.
* Map.m, MemoizedFunction.m, delaunayn.m, inputParser.m,
__publish_latex_output__.m, publish.m, unpack.m, fminbnd.m,
__add_default_menu__.m, gammainc.m, gallery.m, hadamard.m, weboptions.m:
Add newline after keyword "function" or before keyword "endfunction" for
readability.
* getaudiodata.m, pkg.m : Add semicolon to end of line for error() statement.
* movegui.m: Combine mutliple calls to set() into one for performance.
* __unimplemented__.m (missing_functions): Remove missing functions that have
been implemented.
* __vectorize__.m, check_default_input.m, betaincinv.m, gammaincinv.m:
Remove semicolon at end of line with "function" declaration.
* weboptions.m: Remove semicolon at end of line with "if" keyword.
* integrate_adaptive.m, factor.m: Use keyword "endif" rather than bare "end".

Briefly, instead of having the Octave // interpreter block and wait for keyboard input, the terminal // widget would be in charge of accepting keyboard events and use // readline in callback mode. Then the terminal widget and the // interpreter will not block except when executing code. Then we // could have the interpreter qobject directly accept signals. //!
