Define constants of 32 KiB as the upper limit of the marshalled order
and limit protobuf sizes. This value gives lots of buffer in case the
protobufs ever change, but is not as extreme as what we were doing
before in V0 files, which was to use the Uint32 max value.

This change fixes two things which can make reading from a corrupted
orders file inefficient.
* When a corrupted order is detected, but the underlying error is an
UnexpectedEOF (as opposed to a pb.Unmarshal error, for instance), there
is no point in attempting to read from the file another time to find an
additional uncorrupted order - we will continue to get UnexpectedEOF
errors until we seek to the very end of the file and get a normal EOF.
Instead, when UnexpectedEOF occurs, log and send metrics as with other
types of corruption, but do not attempt to read again.
* When a corrupted order is detected, instead of seeking forward only
one byte for the next attempt, seek forward by the size of entryHeader.
This cuts down on the number of iterations needed to find an uncorrupted
order after detecting a corrupted one.

Missed one case of Unmarshal in the previous commit for V0 files (0f4e4969b7)
In V1, unmarshalling was being attempted before the checksum was
verified, so this commit moves those calls to the end of the V1 ReadOne
function.

V1 allows the storagenode to continue reading orders from an
unsent/archived orders file, even if orders in the middle are corrupted.
