Fix some error-handling bugs in python frame filters
While writing a Python frame filter, I found a few bugs in the current
frame filter code. In particular:
* One spot converts a Python long to a CORE_ADDR using PyLong_AsLong.
However, this can fail on overflow. I changed this to use
get_addr_from_python.
* Another spot is doing the same but with PyLong_AsUnsignedLongLong; I
changed this as well just for consistency.
* Converting line numbers can print "-1" if conversion from long
fails. This isn't fatal but just a bit ugly.
I've included a test case for the first issue. The line number one
didn't seem important enough to bother with.

* python/py-framefilter.c (py_print_frame): Use
get_addr_from_python. Check for errors when getting line number.

* gdb.python/py-framefilter.py (ElidingFrameDecorator.address):
New method.
