Add version information to wl_message signatures.

Browse source 
This commit adds version information to wl_message signatures and a
wl_message_get_since function to retrieve.  The since version comes in the
form of a (possible) integer at the begining of the message.  If the
message starts with an integer, then it specifies the "since" version of
that message.  Messages present in version one do not get this "since"
information.  In this way we can run-time detect the version information
for a structure on a per-message basis.
