/*
 * This packet-construction scheme makes the following assumptions:
 *
 * 1. The compiler is able to generate code which addresses one- and two-byte
 * quantities.  In the worst case, this would be done with bit-fields.  If 
 * bit-fields are used it may be necessary to reorder the request fields in
 * this file, depending on the order in which the machine assigns bit fields
 * to machine words.  There may also be a problem with sign extension, as K+R 
 * specify that bitfields are always unsigned.
 *
 * 2. 2- and 4-byte fields in packet structures must be ordered by hand such 
 * that they are naturally-aligned, so that no compiler will ever insert 
 * padding bytes.
 *
 * 3. All packets are hand-padded to a multiple of 4 bytes, for the same reason.

/* In the following typedefs, comments appear that say "LISTof Foo( numItems )",
 * "CLIST of Foo()", and "SINGLE Foo()".   These are used when the protocol 
 * specifies that a request or reply contains a variable length list of 
 * (possibly variable types of) objects.
 *
 * A LISTof list is one for which we have already been given the length.
 * The items in the list are of type "Foo". The number of items in the list
 * appears parenthetically after the type.  ("numItems" in our example.)
 * Any other information needed to parse the list is also passed in the
 * parentheses. (E.g., "tableType" in a list of table entries.)
 *
 * A CLISTof list is the same, except that the first 4 bytes of the list
 * indicate the number of items in the list.  The length may need to be
 * byte-swapped.
 *
 * A SINGLE item of an indeterminate length is indicated in the same
 * manner.  (E.g., a "SINGLE TableEntry()".) Any other information
 * needed to parse the item is also passed in the parentheses.
 * (E.g., "itemMask" in a set of pipeline context attributes.)
 *
 * If no information is given in the parentheses, then the size is
 * implicit.
 *
 * Variable length padding is noted with a comment, with the number
 * of bytes of padding required as calculated from the value in
 * the parentheses.  (number of bytes of padding = n?(3-((n-1)%4):0 , where
 * n is the parenthetical value.)
