c++: rename semantic_type as value_type

Browse Source 
We always refer to the triplet "kind, value, location".  All of them
are nouns, and we support api.value.type and api.location.type.  On
this regard, "semantic_type" was a poor choice.  Make it "value_type".

The test suite was not updated to use value_type, on purpose, to
enforce backward compatibility.

* data/skeletons/c++.m4, data/skeletons/glr.cc, data/skeletons/glr2.cc,
* data/skeletons/variant.hh, doc/bison.texi: Define value_type rather
than semantic_type.
Add a backward compatibility typedef.
* examples/c++/glr/c++-types.yy: Migrate.

** Changes
*** C++ value_type
Prefer value_type to semantic_type to denote the semantic value type,
specified by the `api.value.type` %define variable.
** New features
*** Option -H, --header and directive %header
The option -H/--header supersedes the option --defines, and the directive
%header supersedes %defines. Both --defines and %defines are, of course,
maintained for backward compatibility.

*** Option --html
Since version 2.4 Bison can be used to generate HTML reports. However it
was a two-step process: first bison must be invoked with option --xml, and
then xsltproc must be run to the convert the XML reports into HTML.
