xv: struct "EncodingInfo": add explicit align pad
The align pad is needed so that a in list of struct "EncodingInfo",
the 32-bit fiels in subsequent "EncodingInfo" are aligned.
(the field "encoding" is a 32-bit value, and the field "rate"
contains two 32-bit values)
The xv-protocol-spec does not contain the protocol encoding.
(it specifies the protocol on a higher level)
The X-Server uses function "WriteToClient" to write the list "name"
to the connection:

Function "WriteToClient" does 4-byte alignment padding:
