in struct tm, time.struct_time objects returned by time.gmtime(),
time.localtime() and time.strptime() functions now have tm_zone and
tm_gmtoff attributes.  Original patch by Paul Boddie.

Fix also its value on Windows and Linux according to its documentation:
"adjustable" indicates if the clock *can be* adjusted, not if it is or was
adjusted.

In most cases, it is not possible to indicate if a clock is or was adjusted.

2) Abort the loop for all specials, not only infinity.

3) Make the function more general and distinguish between zero clamping
   and folding down the exponent. The latter case is currently handled
   by setting context->clamp to 0 before calling the function.

  Berch)

2) Remove micro optimization (inline checking for NaN before calling
   mpd_qcheck_nans()) that probably has no benefit in this case.

2) Switch argument order to match the function signature of mpd_calloc()
   (cosmetic change, since the order is irrelevant).

The behavior of MessageDefect is legacy behavior.  The chances anyone is
actually using the undocumented 'line' attribute is low, but it costs
little to retain backward compatibility.  Although one of the costs is
having to restore normal exception behavior in HeaderDefect.  On the
other hand, I'll probably add some specialized behavior there later.

2) Add rigorous error analysis to _mpd_qlog10 (ACL2 proofs exist).

3) Use the relative error as a basis for the interval generation in the
   correction loop (same as in _mpd_qln()).

The strict checks and netmask computing don't make sense if constructed with
a ALL_ONES mask based on addresses. Also fix a bug due to mis-indentation of
a return statement in the same code block.

use. Make the get_entity 'method' a module function as it did not use 'self'.
Delete buggy _find_constructor function that is not needed, at least in 3.x.
Revise get_argspec so all tests pass.  Add and fix NEWS entries.

   List all of them in the comment.

2) Use the recently stated relative error of _mpd_qln() to generate the
   interval for the exact value of ln(x). See also the comment in mpd_qexp().
