pq_abort_locked() prototype.
(conn_switch_isolation_level): fix for new pq_abort_locked()
prototype, and use pq_complete_error() to show error message.
(conn_set_client_encoding): same here.
* psycopg/pqpath.c (pq_execute_command_locked): remove static
modifier.
(pq_complete_error): same here.
(pq_abort_locked): add pgres and error arguments.
(pq_abort): call pq_abort_locked() to reduce code duplication.
* psycopg/pqpath.c (pq_execute_command_locked): add an error
argument to hold an error when no PGresult is returned by PQexec,
rather than using pq_set_critical().
(pq_complete_error): new function that converts the error returned
by pq_execute_command_locked() to a Python exception.
(pq_begin_locked): add error argument.
(pq_commit): use pq_complete_error().
(pq_abort): use pq_complete_error().
(pq_abort_locked): always call pq_set_critical() on error, and
clear the error message from pq_execute_command_locked().
(pq_execute): use pq_complete_error() to handle the error from
pq_begin_locked().
* psycopg/pqpath.c (pq_begin): remove unused function.
* psycopg/connection_type.c (psyco_conn_commit): if conn_commit()
raises an error, just return NULL, since it is now setting an
exception itself.
(psyco_conn_rollback): same here.
* psycopg/connection_int.c (conn_commit): don't drop GIL and lock
connection before calling pq_commit().
(conn_rollback): same here.
(conn_close): use pq_abort_locked().
(conn_switch_isolation_level): same here.
(conn_set_client_encoding): same here.
* psycopg/pqpath.h: add prototype for pq_abort_locked().
* psycopg/pqpath.c (pq_commit): convert function to run with GIL
held, and handle errors appropriately.
(pq_abort): same here.
(pq_abort_locked): new function to abort a locked connection.

* psycopg/pqpath.c (pq_raise): add a "pgres" argument so we can
generate nice errors not related to a particular cursor.
(pq_execute): use pq_begin_locked() rather than pq_begin(). Use
pq_raise() to handle any errors from it.
* psycopg/pqpath.c (pq_execute_command_locked): helper function
used to execute a command-style query on a locked connection.
(pq_begin_locked): a variant of pq_begin() that uses
pq_execute_command_locked().
(pq_begin): rewrite to use pq_begin_locked().
requiring it.
Added a connection flag to store whether E''-style quoting is required: this
avoids repeated PQparameterStatus() calls.
Added a test case to verify correct behavior on strings, unicode and binary
data. Tested with PG versions from 7.4 to 8.3b2, with any server
'standard_conforming_strings' setting and with 'PSYCOPG_OWN_QUOTING' too.
