/**
* Get the proxy string for the specified URI. The proxy string is
* given by the following:
*
* result = proxy-spec *( proxy-sep proxy-spec )
* proxy-spec = direct-type | proxy-type LWS proxy-host [":" proxy-port]
* direct-type = "DIRECT"
* proxy-type = "PROXY" | "HTTP" | "HTTPS" | "SOCKS" | "SOCKS4" | "SOCKS5"
* proxy-sep = ";" LWS
* proxy-host = hostname | ipv4-address-literal
* proxy-port = <any 16-bit unsigned integer>
* LWS = *( SP | HT )
* SP = <US-ASCII SP, space (32)>
* HT = <US-ASCII HT, horizontal-tab (9)>
*
* NOTE: direct-type and proxy-type are case insensitive
* NOTE: SOCKS implies SOCKS4
*
* Examples:
* "PROXY proxy1.foo.com:8080; PROXY proxy2.foo.com:8080; DIRECT"
* "SOCKS socksproxy"
* "DIRECT"
*
* XXX add support for IPv6 address literals.
* XXX quote whatever the official standard is for PAC.
*
* @param aTestURI
* The URI as an ASCII string to test.
* @param aTestHost
* The ASCII hostname to test.
*
* @param result
* result string as defined above.
