- Bytecode.from_traceback() alternate constructor
- current_offset parameter and attribute

Patch by Claudiu Popa

str.encode, bytes.decode and bytearray.decode now use an
internal API to throw LookupError for known non-text encodings,
rather than attempting the encoding or decoding operation and
then throwing a TypeError for an unexpected output type.

The latter mechanism remains in place for third party non-text
encodings.

upgrade pip by default, using the bundled pip provided by the new ensurepip
module.  A new configure option, --with-ensurepip[=upgrade|install|no], is
available to override the default ensurepip "--upgrade" option.  The option
can also be set with "make [alt]install ENSUREPIP=[upgrade|install\no]".

in bin directories for all configurations: non-framework vs framework,
and single arch vs universal builds.  pythonx.y-32 is now always
installed for 64-bit/32-bit universal builds.  The obsolete and
undocumented pythonw* symlinks are no longer installed anywhere.

Also change the argument name to the same name as getpeercert()

CRL enumeration are now two functions. enum_certificates() also returns
purpose flags as set of OIDs.

The flaky buildbots make it hard to detect real issue. This is just a temporary fix until we agree
on a permanent solution.

This patch adds support for binary plists on OSX to plistlib (based
on a patch by 'dpounces').

The patch also cleans up the API for the plistlib module.

PyByteArray_Resize() failure: leave the bytearray object in an consistent state.

If growth < 0, handling the memory allocation failure is tricky here because
the bytearray object has already been modified.  If lo != 0, the operation is
completed, but a MemoryError is still raised and the memory block is not
shrinked. If lo == 0, the bytearray is restored in its previous state and a
MemoryError is raised.

Notify the caller of the failure (MemoryError exception).

repr() is no more platform dependent, SipHash has been fixed
