[PATCH 08/13] checkpolicy: add missing function declarations

["Christian Göttsche" <cgzones@googlemail.com>]

Ideally they should be declared in the corresponding header file, but
the overall include style in the checkpolicy code is quite messy.
Declare them for now in the source file before defining them to silence
related compiler warnings:

    policy_define.c:84:6: error: no previous prototype for function 'init_parser' [-Werror,-Wmissing-prototypes]
    void init_parser(int pass_number)
         ^
    policy_define.c:93:6: error: no previous prototype for function 'yyerror2' [-Werror,-Wmissing-prototypes]
    void yyerror2(const char *fmt, ...)
         ^
