9b18c0e872 add some support for random access of data in packet fifos
dev/pktfifo.cc:
    add support for copying arbitrary data out of a
    packet fifo
dev/pktfifo.hh:
    add support for copying arbitrary data out of a
    packet fifo.
    Add functions to determine where in the fifo a
    particular packet is

36373fa465 Virtualized SINIC fixes
dev/pktfifo.hh:
    we can't modify i because it's used further down to remove
    the packet from the fifo.  Instead, copy the iterator and
    modify that to get the previous packet.
dev/sinic.cc:
    - don't change the transmit state and kick the machine unless
    we're at the head of the txList.
    - add a couple of debugging statements to figure out how far
    along we've gotten in processing a packet.
    - assert that the current tx vnic has something to do when
    we start processing the state machine.

60e92986f7 Add the capability to iterate through the packets in a pktfifo,
and to remove elements in the middle of the fifo.  These elements
do not free space, they are just marked removed.  Space is only
freed from the front of the fifo.

dev/etherpkt.cc:
    serialize the current slack
dev/etherpkt.hh:
    add "slack" to the ethernet packet.  It is to be used by any fifo that
    the packet is currently in to account for extra space that the packet
    may be occupying due to the fifo organization.

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.

a109296bde Fix a bug where we would improperly calculate if the FIFO was
full by adding a reserve feature to the packet fifo which allows
us to reserve space in the fifo if only part of a packet was
copied into the fifo.

dev/ns_gige.cc:
    use the new reserve feature in the fifo to properly determine
    when we're full.  assert that adding a packet to the fifo suceeds.
dev/pktfifo.hh:
    add the ability to reserve space in the fifo.  This is useful for
    partial writing of packets into the fifo.
