h264parse: Fix multiple SEI messages in one SEI RBSP.

I agree for the use of GArray instead of GList, it is more simple. Patch has
been updated.

Also i have a parsing bug which could be caused by more_rbsp_data()
implementation as described in bug 685890:
https://bugzilla.gnome.org/show_bug.cgi?id=685890
For example a SEI NAL payload (extracted from ts file i provided) is:
"00 01 C0 01 01 14 06 01 C4 80 00"
It contains 3 messages: buffering period (00 01 C0), picture timing (01 01 14)
and recovery point (06 01 C4). After the third message, I think
more_rbsp_data() should return FALSE, but actually it returns TRUE because
there is more than 8 bits remaining.
I will investigate this issue.
