/**
* call-seq:
* parser.execute(req_hash, data, start) -> Integer
*
* Takes a Hash and a String of data, parses the String of data filling in the Hash
* returning an Integer to indicate how much of the data has been read. No matter
* what the return value, you should call HttpClientParser#finished? and HttpClientParser#error?
* to figure out if it's done parsing or there was an error.
*
* This function now throws an exception when there is a parsing error. This makes
* the logic for working with the parser much easier. You can still test for an
* error, but now you need to wrap the parser with an exception handling block.
*
* The third argument allows for parsing a partial request and then continuing
* the parsing from that position. It needs all of the original data as well
* so you have to append to the data buffer as you read.
