yacc: remove trailing end of line at end of file

Browse Source 
There are still spurious spaces at the end of some lines.  But this is
addressed in the master branch, and I am reluctant to try to backport
this.

* data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: here.
* tests/calc.at (AT_CHECK_SPACES): New.
Use it.
Be sure not to introduce trailing empty lines in the *.y files.
* NEWS: Doc it.
* cfg.mk (syntax-check): Remove the exception.

Trailing end-of-lines in %parse-param or %lex-param would result in
invalid C++. This is fixed.
** Spurious spaces and end-of-lines
The generated files no longer end (nor start) with empty lines.
* Noteworthy changes in release 2.6.1 (2012-07-30) [stable]
Bison no longer executes user-specified M4 code when processing a grammar.
