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

Actually, according to

the following symbols are still global:

* 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.

Heikki.  It was harmless as long as the clustered index record contained
a long enough local prefix of externally stored columns, to allow secondary
index records to be built without fetching BLOBs.

InnoDB transactions should never look at a clustered index record whose
