867d80d55d Fix annoying bug that lead to dropped packets in the P4 system
dev/pktfifo.cc:
    Make it so that we don't unserialize the size of the fifo, clobering the fact that we were trying to make it bigger, and leading to a misleading config.out that states the un-overwritten max_size.
    Perhaps this should instead be a panic if the size (amount that was serialized) is bigger than the maxsize that was assigned by the configuration file.

b65f365474 fix unserialization of PacketFifo
dev/pktfifo.cc:
    fix unserialization.  calling resize on a list just sticks
    uninitialized garbage into the list.

86836124ed always initalize the size of a packet (forgotten on checkpoints
in some places).  use the constructor for setting the size.

5f6328d9c6 properly implement the fifo _reserved stuff.
dev/pktfifo.cc:
    need to checkpoint _reserved
dev/pktfifo.hh:
    When clearing, clear _reserved
    size() is used for determining how many bytes are in the fifo
    ready to be pulled, so we don't want to add _reserved
    avail() on the other hand is used for determining how much
    free space is in the fifo for adding packets.
    adjust the implementation of empty() and full() to reflect this.
