[PATCH 1/3] Change how Python architecture and language are handled

[Tom Tromey]

>>> -  gdbpy_enter (struct gdbarch *gdbarch, const struct language_defn *language);
>>> +  explicit gdbpy_enter (struct gdbarch *gdbarch = nullptr,
>>> +			const struct language_defn *language = nullptr);

Tom> Will do.

Some of it is documented at the 'class' level:

/* Called before entering the Python interpreter to install the
   current language and architecture to be used for Python values.
   Also set the active extension language for GDB so that SIGINT's
   are directed our way, and if necessary install the right SIGINT
   handler.  */
class gdbpy_enter

However I've added some text to the constructor as well.
