in r2276.  Now the following symbols will be exported when InnoDB is built
as a dynamic plugin:

* the virtual method pointer table of class ha_innodb
* the three variables that MySQL will reference when linking at runtime:

	_mysql_plugin_declarations_
	_mysql_plugin_interface_version_
	_mysql_sizeof_struct_st_plugin_

Furthermore, the following symbols are weak globals, to allow us to access
the built-in InnoDB in the mysqld executable, in case it contains a statically
linked InnoDB:

	builtin_innobase_plugin
	innodb_hton_ptr

pars/pars0grm.h: Remove.  The primary file is include/pars0grm.h.

pars/make_bison.sh: Add from trunk.  Somehow, this file was not merged
at the same time with make_flex.sh.  Add sed magic for replacing the
file name and for hiding yychars, yynerrs, yylval, and yyparse.

pars/pars0grm.c: Apply the changes made by make_bison.sh.

lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static.  It is
referenced from pars0grm.c.

Actually, according to
	nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:

* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs

The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.

The class ha_innodb is renamed from class ha_innobase by a #define.  Thus,
there will be no clash with the builtin InnoDB.  However, there will be some
overhead for invoking virtual methods of class ha_innodb.  Ideas for making
the vtable hidden are welcome.  -fvisibility=hidden is not available in GCC 3.
