Add a new function uses_seh() to the _ctypes extension module. This

used when calling functions, False otherwise.
of bugs in that port. The most annoying ones were due to some subtle differences
between the document ABI and the actual implementation :-(
(there are no python unittests that fail without this patch, but without it
some of libffi's unittests fail).
will return True if Windows Structured Exception handling (SEH) is
used when calling functions, False otherwise.
Currently, only MSVC supports SEH.
Fix the test so that it doesn't crash when run with MingW compiled
_ctypes. Note that two tests are still failing when mingw is used, I
suspect structure layout differences and function calling conventions
between MSVC and MingW.
It seems that the definition of '__attribute__(x)' was responsible for
the compiler ignoring the '__fastcall' attribute on the
ffi_closure_SYSV function in libffi_msvc/ffi.c, took me quite some
time to figure this out.
handler would cause a segfault. This merges in Expat's lib/xmlparse.c
revisions 1.154 and 1.155, which fix this and a closely related problem
(the later does not affect Python).
Moved the crasher test to the tests for xml.parsers.expat.
This backs out the test changes in 46962 which prevented crashes
by not running the tests via a version check. All the version checks
added in that rev were removed from the tests.
Code was added to the error handler in connection.c that seems
to work with older versions of sqlite including 3.1.3.
SQLite versions.
- Added version checks in test suite so that we don't execute tests that we
know will fail with older (buggy) SQLite versions.
Now, all tests should run against all SQLite versions from 3.0.8 until 3.3.6
(latest one now). The sqlite3 module can be built against all these SQLite
versions and the sqlite3 module does its best to not trigger bugs in SQLite,
but using SQLite 3.3.3 or later is recommended.
Heavily revised, comprising revisions:
46640 - original trunk revision (backed out in r46655)
46647 - markup fix (backed out in r46655)
46692:46918 merged from branch aimacintyre-sf1454481
branch tested on buildbots (Windows buildbots had problems
not related to these changes).
Summary of changes:
- support for 'variable sized' data
- support for anonymous structure/union fields
- fix severe bug with certain arrays or structures containing more than 256 fields
the char buffer was requested. Now it actually returns the char buffer if
available or raises a TypeError if it isn't (as is raised for the other buffer
types if they are not present but requested).
Not a backport candidate since it does change semantics of the buffer object
(although it could be argued this is enough of a bug to bother backporting).
