and Latin1 encoders.

Fix error position of the unicode error in ASCII and Latin1
encoders when a string returned by the error handler contains multiple
non-encodable characters (non-ASCII for the ASCII codec, characters out
of the U+0000-U+00FF range for Latin1).

groupindex must a dictionary and indexgroup must be a tuple.

Previously, indexgroup was a list. Use a tuple to reduce the memory usage.

Frame.is_other_python_frame() now also handles _PyCFunction_FastCallDict()
frames.

Thanks to the new code to handle fast calls, python-gdb.py is now also able to
detect the <built-in id method of module ...> frame.

A pattern is equal to itself.

Typo catched by Serhiy Storchaka, thanks!

Replace int(value.address)+offset with value.cast(unsigned char*)+offset.

It seems like int(value.address) fails on old versions of GDB.

Start 3.6.0rc1. (Note, patch level was incorrectly set to 3.6.0b4+ following b3. It is now b4+ again.)

PyStructSequence_Field, PyStructSequence_Desc, and wrapperbase are now of
type "const char *" rather of "char *".
