This commit also contains a forward port of
nodejs#14232 to confirm that 4.x and 6.x
behave identically with respect to the port argument.

root_cert_vector currently has file scope and external linkage, but is
only used in the NewRootCertsStore function. If this is not required to
be externally linked perhaps it can be changed to be static and function
scoped instead.

root_cert_store is defined as extern in node_crypto.h but only used in
node_crypto.cc. It is then set using SSL_CTX_set_cert_store. The only
usages of SSL_CTX_get_cert_store are in node_crypto.cc which would all
be accessing the same X509_STORE through the root_cert_store pointer as
far as I can tell. Am I missing something here?

This commit suggests removing it from the header and making it static
in node_crypto.cc.
