gdb: move pascal_language into p-lang.h
Move the pascal_language class declaration into the p-lang.h header file. This allows for the function implementations to be spread over the different p-*.c files without the need for global trampoline functions. As a consequence of this change many of the Pascal value and type printing helper functions have become member functions within the pascal_language class. There should be no user visible changes after this commit. gdb/ChangeLog: * p-exp.y (exp): Update call to pascal_is_string_type. (pascal_parse): Rename to... (pascal_language::parser): ...this. * p-lang.c (is_pascal_string_type): Rename to... (pascal_is_string_type): ...this. (pascal_one_char): Rename to... (pascal_language::print_one_char): ...this.
