This function iterates through the TLS extensions as passed in
data , passing the individual extension data to callback. The
data must conform to Extension extensions<0..2^16-1> format.

If flags is GNUTLS_EXT_RAW_TLS_FLAG_CLIENT_HELLO then this function will parse the extension data from the position, as if the packet in
data is a client hello (without record or handshake headers) - as provided by gnutls_handshake_set_hook_function().

The return value of the callback will be propagated.
