Libor Pechacek 0367bb5f1b Distinguish between ignored and malformed packets
When there is a peer speaking PTPv1 in the network we want to silently ignore
the packets instead of flooding system log with error messages.  At the same
time we still want to report malformed packets.  For that we reuse standard
error numbers and do more fine-grained error reporting in packet processing
routines.

Geoff Salmon f4e8f5be3f support TLVs with flexible size
These flexible TLVs don't need to be represented as a single packed
struct directly in the message buffer. Instead a separate struct
contains pointers to the individual parts of the TLV in the message
buffer. The flexible TLV can only be the last TLV in a message.

Richard Cochran eed8ed05c8 Add an option to assume two step messaging.
Some commercial 802.1AS switches do not feel obliged to set the two step
flag. When we try to synchronize to their apparent one step sync messages,
nothing good happens. This commit adds a global option to work around the
issue.

Richard Cochran d7a67e9f89 Prevent message buffer corruption on receive.
An oversize incoming packet might overwrite the reference counter in a
message. Prevent this by providing a buffer large enough for the largest
possible packet.

This will also be needed to support TLV suffixes.
