This patch fixes a reference leak and improves the error handling in the converter mapping code. Rather accidentially it also drops the cleanup: label and the gotos ;)

(Bug 1521274)
Fix problem with callproc() when it is used before execute() (which is
legal). (Bug 1541124)

MySQL-5.0).
Mapped some new error codes to DataError, which has always existed,
but never had anything mapped to it.
Cleaned set_character_set() a bit.
Added new connection option sql_mode and correspond set_sql_mode()
method.
* _mysql.c: raise ProgrammingError for certain methods if they
are used on Result object created with conn.use_result(),
since they don't make sense.
* setup.py: Reimplement quote stripping around directory names.
This seems to be a bug in older versions of mysql_config
* cursors.py: If a unicode query string is passed, encode it in
the connection's character set.
and it seems to cause problems on some platforms or versions of MySQL
(most likely 3.23's mysql_config)
* removed use of weak references; I don't think they were needed any more,
and they caused problems in some of the threaded tests.
* applied patch #1188359: If converters are passed in, use a copy().
* Version 1.2.1c2.
* Reworked Unicode support; please test
* Make Binary() create an array('c')
* Clean up Cursors a bit.
* Add a TimeDelta factory function, even though not in the API spec.
