Streams for ssl:// transports can now be configured to use a specific
crypto method (SSLv3, SSLv2 etc.) by calling

stream_context_set_option($ctx, "ssl", "crypto_method", $crypto_method)

where $crypto_method can be one of STREAM_CRYPTO_METHOD_SSLv2_CLIENT,
STREAM_CRYPTO_METHOD_SSLv3_CLIENT, STREAM_CRYPTO_METHOD_SSLv23_CLIENT
or STREAM_CRYPTO_METHOD_TLS_CLIENT. SSLv23 remains the default crypto
method.

This change makes it possible to fopen() SSL URLs that are only
provided using SSL v3.
Add unit test that covers setting the crypto method.
