58e4134a1c Issue #23611: Serializing more "lookupable" objects (such as unbound methods 
or nested classes) now are supported with pickle protocols < 4.

d5d818d40b Issue #18473: Fixed 2to3 and 3to2 compatible pickle mappings. 
Fixed ambigious reverse mappings.  Added many new mappings.  Import mapping
is no longer applied to modules already mapped with full name mapping.

Added tests for compatible pickling and unpickling and for consistency of
_compat_pickle mappings.

d05c9ff845 Issue #6784: Strings from Python 2 can now be unpickled as bytes objects. 
Initial patch by Merlijn van Deen.

I've added a few unrelated docstring fixes in the patch while I was at
it, which makes the documentation for pickle a bit more consistent.

b6a2f2a0d1 Make framing optional in pickle protocol 4. 
This will allow us to control in the future whether to use framing or not.
For example, we may want to turn it off for tiny pickle where it doesn't
help.

The change also improves performance slightly:

7c5e094cbf Make C and Python implementations of pickle load STRING opcodes the same way. 
The C version tried to remove trailing whitespace between the last quote and
the newline character. I am not sure why it had this because pickle never
generated such pickles---for this to happen repr(some_string) would need to
return trailing whitespace. It was maybe there to make it easier for people
to write pickles in text editors. Anyhow, the Python version doesn't do this
so there is no point keeping this around anymore.

Also, I've changed the exception raised when a bad pickle is encountered.
Again this unlikely to make much difference to anyone though it does make
testing slightly nicer for us.
