File nodejs-openssl-missing-api.patch of Package nodejs

NodeJS 0.10 uses APIs introduced with OpenSSL 1.0.0.  To make it build against
OpenSSL 0.9.8 we must revert some API changes (298f6bf) and copy some missing
structs/functions from OpenSSL 1.0.0.

A better long-term solution might be to have the RPM depend on openssl>=1.0.0
and statically link with the bundled OpenSSL on platforms lacking it.
