renamed scintilla.[ch] to symbols.[ch]: fixes builds on case-insensitive file systems

* There is a "Scintilla.h" as well.
* should fix macOS and builds on native Windows hosts
* It wasn't practical to refer to the Scintilla includes using paths since
  the Scintilla location is configurable (--with-scintilla).
  So we'd have to write something like #include <include/Scintilla.h>.
  For Scinterm we cannot avoid collisions neither as its path is also
  configurable (--with-scinterm).
  Effectively, we must prevent name clashes across SciTECO and all
  of Scintilla and Scinterm.
