Avoid the locks dance when reading the connection socket number.
...
It is a fast and non critical operation, so the lock is not required.
Furthermore, called from the wait callback creates a deadlock.

Dropped redundant call to conn_notice_process().
...
If the connection is sync, notices will be processed by pq_fetch()
downstream.
If the connection is async, here we have only sent the query: no result
is ready yet, and neither notices have had a chance to arrive: they will
be retrieved later by pq_is_busy().
Added tests to check the above statement don't break.

Remove fileno() and poll() from cursors
...
Instead, the code should be using the fileno() and poll() methods of
the cursor's connection. Handle the case when poll() is called on an
already built connection as a request to poll the asynchronous query
(if there is one) and get NOTIFY events.
Update the tests to reflect that change, add a test for NOTIFY.

Handle errors in asynchronous queries.
...
Do it by keeping the reference to the last PGresult in the cursor and
calling pq_fetch() before ending the asynchronous execution. This
takes care of handling the possible error state of the PGresult and
also allows the removal of the needsfetch flag, since now after
execution ends the results are already fetched and parsed.

Set the execution status to ASYNC_READ after flushing all output.
...
Without this a query that did not get flushed completely to the server
would cause cursor.poll() to always go into the curs_poll_send()
branch even if it was retuning ASYNC_READ.

Make the first poll() of an asynchronous connection return POLL_WRITE.
...
This hides from the user the libpq's implementation detail of
requiring the first select() to wait for the connection socket to
become writable and makes it possible to have a uniform select loop
for both cursors and connections, in which you always start by polling
the object and then acting according to the result from poll().
Idea and implementation by Daniele Varrazzo.

Make polling a cursor that's not in an async query raise an exception.
...
If there is an asynchronous query, polling a cursor that did not
initiate it will raise an exception. Polling while there is no
asynchronous query underway still works, because the user needs to
have a way to get asynchronous NOTIFYs.

Added a test to check poll() correctly calls PQflush.
...
When a large query is sent to the backend (and probably in high
concurrency situations), writing the query could block. In
this case PQflush() should be called until it returns 0. The test checks
this is done correctly.
