Certain callback APIs allow the callback to request async processing
by trickling a particular error value up the stack to the application
as an error return from the handshake function. In those cases,
SSL_want() returns a code specific to the type of async processing
needed.
The create_ssl_connection() helper function for the tests is very
helpful for several things, including creating API tests. However,
it does not currently let us test the async processing functionality
of these callback interfaces, because the special SSL error codes
are treated as generic errors and the helper continues to loop until
it reaches its maximum iteration count.
Add a new parameter, 'want', that indicates an expected/desired
special SSL error code, so that the helper will terminate when
either side reports that error, giving control back to the calling
function and allowing the test to proceed.

(Merged from https://github.com/openssl/openssl/pull/2279)
A BIO_read() 0 return indicates that a failure occurred that may be
retryable. An SSL_read() 0 return indicates a non-retryable failure. Check
that if BIO_read() returns 0, SSL_read() returns <0. Same for SSL_write().
The asyncio test filter BIO already returns 0 on a retryable failure so we
build on that.

Split the create_ssl_connection() helper function into two steps: one to
create the SSL objects, and one to actually create the connection. This
provides the ability to make changes to the SSL object before the
connection is actually made.

This commit adds some session API tests, and in particular tests the
modified behaviour of SSL_set_session() introduced in the last commit. To
do this I have factored out some common code from the asynciotest into a
new ssltestlib.c file. I've also renamed getsettest to sslapitest as this
more closely matches what it now is!

This adds an async IO test. There are two test runs. The first one does
a normal handshake with lots of async IO events. The second one does the
same but this time breaks up all the written records into multiple records
of one byte in length. We do this all the way up until the CCS.
