Implement ability to extract network traffic (CAN, LIN, Ethernet, etc.) from VSA message records on disk. Add a method to Device class that uses the VSAParser and the individual record types to extract messages from the VSA message records and pass them back to the communication system. This routes messages such that it appears as if they were discovered live instead of read from disk. The parse process (in Device) requires determination of metadata about the VSA file system on a device before it can begin extracting messages. This currently only handles data captured from the current coremini script on a device.
Reading disk data is currently accomplished by redirecting the raw input stream
for the duration of the acquisition, during which no other operation can be
carried out. This change moves disk data reading into the packetizer so the
familiar request/reply with message filters can be used. To accomplish this the
deprecated ISOPIC network type was dropped because the two messages share this
network ID.
Also fixes live data packet lengths which were off-by-one.
Previously, we had to copy an entire block out of the
old cache every time we wanted to read even a single
byte from it.
This ended up being a fairly significant performance
issue, in addition to the fact that the caching code
was duplicated.
