Hello,

  I prepared fix for Bug "Autocommit and Cancel". It's woking patch
(it's used #ifded NOT_USED). The main changes are in using cancelable
PQsendQuery (it could be ok) and in cleaning and correcting
CC_send_query. CC_send_query should be equivalent with old one
except adding some QR_set_aborted. I'm not sure if it's ok.
It passed ok throught few tests.

Please could you take a look at this patch? Comments are welcome.

Thanks

Luf
