---------------------------------------------------------

Commit 7749210210e339b286b22067a1c1104e7c6fa370 in qpid-proton's branch refs/heads/0.13.x
from [~dnwe]

PROTON-1249: Safeguard type initialisations.

In #readValue() for ArrayType, BinaryType, ListType and MapType
decoding, if the 'count' specified is very large then it is likely to
trigger an OutOfMemoryException. As these can come from an external data
source, during the SASL init for example, there is a potential for a
denial of service. The fix is to throw an IllegalArgumentException if
the count value is larger than the amount of data available in the
received bytes.
