shuo li updated THRIFT-5299:
----------------------------
Description:
While reviewing code, I discovered a bug in compact protocol.
The seq_id in message header is decoded with integer-encoding's i32, which uses
zigzag decode implicitly.
EDIT: correct the title and desc.

While reviewing code, I discovered a bug in compact protocol.
The length of byte is decoded with integer-encoding u32, which does not do
zigzag decode first.
The fix should be use i32 as decode, then convert to unsigned value.
In specification, it is explicitly specified that the length field is SIGNED.
Summary: rs implementation compact protocol seq_id should not use
zigzag encoding. (was: rs implementation compact protocol varint
implementation is wrong)
> rs implementation compact protocol seq_id should not use zigzag encoding.
