This PR uses a different approach than Aviv's proposed patch in bpo. I use sqlite3_errcode() to fetch the exception class, and sqlite3_extended_errcode() to set the exception attributes. IMO, this is clearer and more future proof than using a mask in get_exception_class().

from the tests:

Traceback (most recent call last):
  File "/home/runner/work/cpython/cpython/Lib/sqlite3/test/dbapi.py", line 276, in test_error_code_on_exception
    err_code = SQLITE_CANTOPEN
               ^^^^^^^^^^^^^^^
NameError: name 'SQLITE_CANTOPEN' is not defined

@dimaqq:

NameError: name 'SQLITE_CANTOPEN' is not defined

Yes, SQLITE_CANTOPEN_ISDIR is returned on Windows and if forgot to prefix it with sqlite.. But, I need to revisit the extended result code ifdefs anyway, so I've marked this PR as draft for now.

PTAL, @dimaqq :)

The AMD64 Arch Linux Asan Debug PR buildbot failure is unrelated. See python/buildmaster-config#275
