api.header.include: document it, and fix its default value

Browse Source 
While defining api.header.include worked as expected, its default
value was incorrectly defined.  As a result, by default, the generated
parsers still duplicated the content of the generated header instead
of including it.

* data/skeletons/yacc.c (api.header.include): Fix its default value.
* tests/output.at: Check it.
* doc/bison.texi (%define Summary): Document api.header.include.
While at it, move the definition of api.namespace at the proper
place.
