[issue9051] Improve pickle format for aware datetime instances

[Alexander Belopolsky]

Alexander Belopolsky <belopolsky at users.sourceforge.net> added the comment:

The datetime module provides compact pickled representation for date, datetime, time and timedelta instances:

type: size
date: 34
datetime: 44
time: 36
timedelta: 37


On the other hand, current pickle size for timezone is 64 and the size of an aware datetime instance is 105 bytes.

Since stability is important for pickle format, the best format should be developed before the first release to include timezone class.
