ISSUE:       4483
TITLE:       RDB$GET_CONTEXT/RDB$SET_CONTEXT parameters incorrectly described as CHAR NOT NULL instead of VARCHAR NULLABLE
DESCRIPTION:
JIRA:        CORE-4156
FBTEST:      bugs.core_4156
NOTES:
    [12.12.2023] pzotov
    Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
    ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
    Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
