Missing support for unsigned 32-bit integer field value type

[TheCount]

When sending a message with a header with value kind 'i' (meaning long-uint) as specified in AMQP 0-9-1 section 4.2.1, the rabbitmq-server responds with Connection.Close with an obscure "INTERNAL_ERROR". I haven't had the time to build a server and the management tool from the repositories right now, but the issue seems to be in rabbit_binary_parser.erl, lines 41 and onward, where the case for 'i' is simply missing.

There are bunch of types from 0-9-1 missing in rabbit_binary_parser. I'm not sure though what RType values should be used for them.
Missing types:
'B' short-short-uint
'U' short-int
'u' short-uint
'i' long-uint
'L' long-long-int

And there are also 's' type tag, which means 'short-string' which is OCTET *string-char and in current implementation it is being parsed like signed short

@hairyhum take a look at AMQP 0-9-1 Errata as well as AMQP 0-8 and 0-9-1 differences.

So we can at least add 'B', 'u', and 'i' types as 'unsignedbyte', 'unsignedshort' and 'unsignedint' respectively.
