avoid python exception in FrameDecorator.py
This fixes a bug in FrameDecorator.py.
FrameVars seems to assume that Frame.block can return None if there is
no block. However, it actually throws an exception.
I saw this bug while developing a frame filter, but unfortunately I
don't know how to reproduce it. It seems to me that the SAL tests in
_is_limited_frame should exclude the bad cases; and in my attempts to
write a test they do.
Nevertheless I think the fix is reasonably obvious and ought to go in.

fix erroneous error-handling in frame filter code
This fixes PR python/16487.
The bug here is that the function-name-handling code in py_print_frame
had a small logic error (really a misplaced closing brace). This
error could lead to a Py_DECREF(NULL), which crashes.
This patch fixes the bug in the obvious way.
Built and regtested on x86-64 Fedora 18. New test case included.

fix crash in frame filters
apply_frame_filter calls ensure_python_env before computing the
gdbarch to use. This means that python_gdbarch can be NULL while in
Python code, and if a frame filter depends on this somehow (easy to
do), gdb will crash.
The fix is to compute the gdbarch first.
Built and regtested on x86-64 Fedora 18.
New test case included.
