- Remove vestiges of cvs annotate support
Update lang/pypy3-devel to 2.4.0.

Changes:
 * Carry across _sqlite.py fix from lang/pypy
 * Strip cffi shared libraries (from lang/pypy)

Change Log:
 - Various fsencode PEP 383 related fixes to the posix module (readlink, uname,
   ttyname and ctermid) and improved locale handling
 - Fixed a couple different crashes related to parsing Python 3 source code
 - internal refactoring in string and GIL handling which led to significant
   speedups
 - improved handling of multiple objects (like sockets) in long-running
   programs. They are collected and released more efficiently, reducing memory
   use. In simpler terms - we closed what looked like a memory leak
