*
* This is the parser for the packetdrill script language. It is
* processed by the bison parser generator.
*
* For full documentation see: http://www.gnu.org/software/bison/manual/
*
* Here is a quick and dirty tutorial on bison:
*
* A bison parser specification is basically a BNF grammar for the
* language you are parsing. Each rule specifies a nonterminal symbol
* on the left-hand side and a sequence of terminal symbols (lexical
* tokens) and or nonterminal symbols on the right-hand side that can
* "reduce" to the symbol on the left hand side. When the parser sees
* the sequence of symbols on the right where it "wants" to see a
* nonterminal on the left, the rule fires, executing the semantic
* action code in curly {} braces as it reduces the right hand side to
* the left hand side.
*
* The semantic action code for a rule produces an output, which it
* can reference using the $$ token. The set of possible types
* returned in output expressions is given in the %union section of
* the .y file. The specific type of the output for a terminal or
* nonterminal symbol (corresponding to a field in the %union) is
* given by the %type directive in the .y file. The action code can
* access the outputs of the symbols on the right hand side by using
* the notation $1 for the first symbol, $2 for the second symbol, and
* so on.
*
* The lexer (generated by flex from lexer.l) feeds a stream of
* terminal symbols up to this parser. Parser semantic actions can
* access the lexer output for a terminal symbol with the same
* notation they use for nonterminals.
*
* Here's an example rule with its semantic action in {} braces:
*
* tcp_option
* ...
* | MSS INTEGER {
* $$ = tcp_option_new(...);
* ...
* $$->data.mss.bytes = htons($2);
* }
*
* This rule basically says:
*
* When the parser wants to see a tcp_option, if it sees an MSS from
* the lexer followed by an INTEGER from the lexer then run the
* action code that (a) stores in the output $$ a pointer to a
* struct tcp_option object, and then (b) stores in that object the
* value of the INTEGER token (accessed with $2).
*
*/
/* The first part of the .y file consists of C code that bison copies
* directly into the top of the .c file it generates.
