Log message:
Update to 4.48.0. From the changelog:

- work around brain-damaged change in Python's poplib which causes
  message retrieval errors if any line of a message has more than
  2048 characters in it.

  J. Weller-Fahy.

Update to 4.47.0. From the changelog:

- try to work around pathological breakage in one random POP server
  implementation. Thanks: Michael Thomas Kockmeyer.
- remove dead marc.theaimsgroup.com list archive from docs. Thanks:
  Miroslav Rovis.
- bugfix: if you combined IMAP IDLE mode with delete_after, getmail would,
  after remaining connected to the server for the number of days
  configured, begin deleting messages immediately after retrieval
  instead of after the configured delay. Now fixed. Thanks:
  Johannes Weißl.

Log message:
No need to have two variables for the same logic.
Replace PYTHON_PATCH_SCRIPTS with REPLACE_PYTHON.

Log message:
Mark packages as not ready for python-3.x where applicable;
either because they themselves are not ready or because a
dependency isn't. This is annotated by
PYTHON_VERSIONS_INCOMPATIBLE=  33 # not yet ported as of x.y.z
or
PYTHON_VERSIONS_INCOMPATIBLE=  33 # py-foo, py-bar
respectively, please use the same style for other packages,
and check during updates.

Use versioned_dependencies.mk where applicable.
Use REPLACE_PYTHON instead of handcoded alternatives, where applicable.
Reorder Makefile sections into standard order, where applicable.

Remove PYTHON_VERSIONS_INCLUDE_3X lines since that will be default
with the next commit.

Whitespace cleanups and other nits corrected, where necessary.

Log message:
