Add elliptic curve support to QSsl

Add possibility to get length and other information of EC based
certificates. Also it is possible to parse those public/private
keys from PEM and DER encoded files.

Based on patch by Remco Bloemen

[ChangeLog][QtNetwork][SSL/TLS support] It is now possible to
parse elliptic curve certificates.
