int parse_select	(	char **	p,
		select_t **	s
	)

Parse select string into select structure s and moves pointer p to the first unused char.

 * The select identifier must be of the form:
 *   [@] <sel_id> [ '.' <sel_id> ...]
 *   
 * Where 
 *       <sel_id> = <id> |
 *                  <id> '[' <idx> ']'
 *       <id> = [a-zA-Z0-9_]+
 *       <idx> = <number>  | '-' <number> | <string>
 *       <string> = '"' <ascii> '"' | 
 *                  '\"' <ascii> '\"'
 *
 * Examples:
 *     @to.tag
 *     @hf_value["contact"]
 *     @msg.header["SER-Server-ID"]
 *     @eval.pop[-1]
 *     contact.uri.params.maddr
 *     cfg_get.rtp_proxy.enabled 

Parameters:

	p	- double string (asciiz) pointer, *p is moved to the first char after the select identifier
	s	- the result will be stored here

Returns:

< 0 on error, 0 on success
