// KD_PACKETS are the low level data format used in KD. All packets
// begin with a packet leader, byte count, packet type. The sequence
// for accepting a packet is:
//
//  - read 4 bytes to get packet leader.  If read times out (10 seconds)
//    with a short read, or if packet leader is incorrect, then retry
//    the read.
//
//  - next read 2 byte packet type.  If read times out (10 seconds) with
//    a short read, or if packet type is bad, then start again looking
//    for a packet leader.
//
//  - next read 4 byte packet Id.  If read times out (10 seconds)
//    with a short read, or if packet Id is not what we expect, then
//    ask for resend and restart again looking for a packet leader.
//
//  - next read 2 byte count.  If read times out (10 seconds) with
//    a short read, or if byte count is greater than PACKET_MAX_SIZE,
//    then start again looking for a packet leader.
//
//  - next read 4 byte packet data checksum.
//
//  - The packet data immediately follows the packet.  There should be
//    ByteCount bytes following the packet header.  Read the packet
//    data, if read times out (10 seconds) then start again looking for
//    a packet leader.

// This is the format for the trace data passed back from the kernel to
// the debugger to describe multiple calls that have returned since the
// last trip back.  The basic format is that there are a bunch of these
// (4 byte) unions stuck together.  Each union is of one of two types: a
// 4 byte unsigned long integer, or a three field struct, describing a
// call (where "call" is delimited by returning or exiting the symbol
// scope).  If the number of instructions executed is too big to fit
// into a USHORT -1, then the Instructions field has
// TRACE_DATA_INSTRUCTIONS_BIG and the next union is a LongNumber
// containing the real number of instructions executed.
//
// The very first union returned in each callback is a LongNumber
// containing the number of unions returned (including the "size"
// record, so it's always at least 1 even if there's no data to return).
//
// This is all returned to the debugger when one of two things
// happens:
//
//   1) The pc moves out of all defined symbol ranges
//   2) The buffer of trace data entries is filled.
//
// The "trace done" case is hacked around on the debugger side.  It
// guarantees that the pc address that indicates a trace exit never
// winds up in a defined symbol range.
//
// The only other complexity in this system is handling the SymbolNumber
// table.  This table is kept in parallel by the kernel and the
// debugger.  When the PC exits a known symbol range, the Begin and End
// symbol ranges are set by the debugger and are allocated to the next
// symbol slot upon return.  "The next symbol slot" means the numerical
// next slot number, unless we've filled all slots, in which case it is
// #0.  (ie., allocation is cyclic and not LRU or something).  The
// SymbolNumber table is flushed when a SpecialCalls call is made (ie.,
// at the beginning of the WatchTrace).
