Changes to make __file__ a proper Unicode object, using the default
filesystem encoding.
This is a bit tricky because the default filesystem encoding isn't
set by the time we import the first modules; at that point we fudge
things a bit.  This is okay since __file__ isn't really used much
except for error reporting.
Tested on OSX and Linux only so far.

Also fix some indentation.

returned by 'et' need to be freed after usage.

fix the error message of the 't' format unit, in getargs.c, so that it
asks for bytes, instead of string.

Adds a DBShelf __repr__ method to not raise an exception when the DB is closed.

Eliminate use of PyBUF_CHARACTER flag which is no longer part of the buffer interface.  Fix up array module to export the correct format for wide-builds.

Fix problems with memoryview object.  There is still more to do to finish PEP 3118.  The memory-view object needs to be fleshed out and the struct module needs to be modified.

Add macros for checking for long double and defining the size of long double on the platform.  Ctypes and Struct module will both need them.

Fix Issue 1268 with the array module by backing-out the 'w' addition.  All builds will continue to use 'u' for unicode.

Fixes http://bugs.python.org/issue1233 - bsddb.dbshelve.DBShelf.append
was useless due to inverted logic.  Also adds a test case for RECNO dbs
to test_dbshelve.

with a bytes instance (as this will soon print something differently).

Only the filename is still a PyString now.
(We'll need to deal with the default filesystem encoding to do it right.)

to guarantee the claim that it doesn't set an exception.

object with PyString calls and not checking errors.  This caused the display
of syntax errors to be deformed.

Caused file save to fail. Bug 1130.
