* The following three routines (netcam_url_match, netcam_url_parse and

* expressions (which is outside the scope of this module, so detailed
* comments are not provided). netcam_url_parse is called from netcam_start,
* and puts the "broken-up" components of the URL into the "url" element of
* the netcam_context structure.
*
* Note that the routines are not "very clever", but they work sufficiently
* well for the limited requirements of this module. The expression:
* (http)://(((.*):(.*))@)?([^/:]|[-.a-z0-9]+)(:([0-9]+))?($|(/[^:]*))
* requires
* 1) a string which begins with 'http', followed by '://'
* 2) optionally a '@' which is preceded by two strings
* (with 0 or more characters each) separated by a ':'
* [this is for an optional username:password]
* 3) a string comprising alpha-numerics, '-' and '.' characters
* [this is for the hostname]
* 4) optionally a ':' followed by one or more numeric characters
* [this is for an optional port number]
* 5) finally, either an end of line or a series of segments,
* each of which begins with a '/', and contains anything
* except a ':'
