(ZIP file spec. says in section K, "General notes" in point 1 that unless
specified otherwise values are unsigned and they are not specified as signed in
the spec).

Closes bug #679953.  Thanks Jimmy Burgett.

[Bug #835415] AIX can return modes that are >65536, which causes an OverflowError.  Fix from Albert Chin

Remove <p> before <table> (tidy complains)

* Rename "trap_enablers" to just "traps".
* Simplify names of "settraps" and "setflags" to just "traps" and "flags".
* Show "capitals" in the context representation
* Simplify the Context constructor to match its repr form so that only
  the set flags and traps need to be listed.
* Representation can now be run through eval().

Improve the error message when the Decimal constructor is given a float.

The test suite no longer needs a duplicate reset_flags method.

Replace example with simpler alternative using PyGILState_{Ensure,Require).  Can someone please confirm this change is OK?

any restriction on the return type (like unicode.encode() et al. do).

create a testing method that can be called to make sure that the handling of
the .pth file was correct.

incorrect declaration for ypall_callback in /usr/include/rpcsvc/ypcInt.h .
Shouldn't hurt any code since the differences are unsigned long instead of int and
void * instead of char *.  Removes warning about improper function pointer
assignment during compilation.

match old verion's argument list (overlooked since API of the file is
undocumented).

  public.
* Removed the non-signal conditions from __all__.
* Removed the XXX comment which was resolved.
* Use ^ instead of operator.xor
* Remove the threading lock which is no longer necessary.

* Map conditions to related signals.
* Make contexts unhashable.
* Eliminate used "default" attribute in exception definitions.
* Eliminate the _filterfunc in favor of a straight list.

Docs:
* Eliminate documented references to conditions that are not signals.
* Eliminate parenthetical notes such as "1/0 --> Inf" which are no
  longer true with the new defaults.

* add more __init__ tests

* use assertions instead of tests after internal calls that can't fail.
* expand test coverage
