The following entry points have been made async aware:
SSL_accept
SSL_read
SSL_write

Also added is a new mode - SSL_MODE_ASYNC. Calling the above functions with
the async mode enabled will initiate a new async job. If an async pause is
encountered whilst executing the job (such as for example if using SHA1/RSA
with the Dummy Async engine), then the above functions return with
SSL_WANT_ASYNC. Calling the functions again (with exactly the same args
as per non-blocking IO), will resume the job where it left off.

Provides support for running asynchronous jobs. Currently this is completely
stand alone. Future commits will integrate this into libssl and s_server/
s_client. An asynchronous capable engine will be required to see any benefit
from this capability.

We use the sysconf function to provide details about the page size in the

The problem remained unnoticed so far, because it's never called by default.
You have to craft OPENSSL_ppccap environment variable to trigger the problem.

It was also found that stich performs suboptimally on AMD Jaguar, hence

Print certificate details using accessor functions.

Since X509_CERT_AUX_print is only used in one place and can't
be used by applications (it uses an internal X509_CERT_AUX structure)
this has been removed and replaced by a function X509_aux_print which
takes an X509 pointer instead.

This also changes BIO_C_GET_CONNECT to actually return the port

Pull out the state machine into a separate sub directory. Also moved some
