Victor Stinner 7667f58151 Issue #23517: fromtimestamp() and utcfromtimestamp() methods of
datetime.datetime now round microseconds to nearest with ties going to nearest
even integer (ROUND_HALF_EVEN), as round(float), instead of rounding towards
-Infinity (ROUND_FLOOR).

pytime API: replace _PyTime_ROUND_HALF_UP with _PyTime_ROUND_HALF_EVEN. Fix
also _PyTime_Divide() for negative numbers.

_PyTime_AsTimeval_impl() now reuses _PyTime_Divide() instead of reimplementing
rounding modes.

datetime.timedelta uses rounding mode ROUND_HALF_EVEN again.

It is very unlikely that they can occur in real code for now.

Victor Stinner a53ec7a91a Backed out changeset b690bf218702
Issue #23517: the change broke test_datetime. datetime.timedelta() rounding
mode must also be changed, and test_datetime must be updated for the new
rounding mode (half up).

Larry Hastings 2623c8c23c Issue #20530: Argument Clinic's signature format has been revised again.
The new syntax is highly human readable while still preventing false
positives.  The syntax also extends Python syntax to denote "self" and
positional-only parameters, allowing inspect.Signature objects to be
totally accurate for all supported builtins in Python 3.4.

Larry Hastings 581ee3618c Issue #20326: Argument Clinic now uses a simple, unique signature to
annotate text signatures in docstrings, resulting in fewer false
positives.  "self" parameters are also explicitly marked, allowing
inspect.Signature() to authoritatively detect (and skip) said parameters.

Issue #20326: Argument Clinic now generates separate checksums for the
input and output sections of the block, allowing external tools to verify
that the input has not changed (and thus the output is not out-of-date).

Victor Stinner 93037498d1 Fix time.mktime() and datetime.datetime.timestamp() on AIX
On AIX, the C function mktime() alwaysd sets tm_wday, even on error. So tm_wday
cannot be used as a sentinel to detect an error, we can only check if the
result is (time_t)-1.

time.ctime(), gmtime(), time.localtime(), datetime.date.fromtimestamp(),
datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp() now
raises an OverflowError, instead of a ValueError, if the timestamp does not fit
in time_t.

datetime.datetime.fromtimestamp() and datetime.datetime.utcfromtimestamp() now
round microseconds towards zero instead of rounding to nearest with ties going
away from zero.

Gregory P. Smith 5831bd2f3b Remove an unnecessary extra copy of the bytes hash function.
This copy also had a bug in it, it fails to incorporate the length
into the hash by using it as the loop variable so it'll always be -1
by the time it is XORed in.

As such: I'm doing this only in Python 3.3 and not backporting as it
would change the existing hash behavior of datetime objects.
