This method is used to parse the custom OpenStreetMap shortlink algorithm
that encodes lat, lon, and zoom. The previous version,
MapUtils.decodeShortLocString(), only parsed lat, lon from the shortlink.
It seems this code is quite out of date, because none of the URL formats
listed in the tests seem to work. This commit updates the URL formats in
the tests, then makes all of them parse properly. It also changes the
parsing technique, leveraging java.net.URL's built-in parsing abilities to
assist. Also, I plan on adding a lot more URL formats, so the current code
structure made it very difficult to add to. So each service will be split
out into its own section, starting here.
In order to maintain privacy when sharing location, this changes the shared
location link to use HTTPS, thereby hiding the location info from anyone
who might be snooping on the WiFi, ISP, internet, etc.
Unfortunately, http://osm.org does not yet work with HTTPS, but the
standard OSM URLs are short enough to fit into a text message. They are
planning on supporting https://osm.org in the future:

Some networks require a proxy to get internet beyond the firewall, and
proxies are also useful for channeling all traffic through circumvention
and privacy proxies like Tor, I2P, Psiphon, etc. In places where the
connection to download tiles might be blocked, using a proxy can give the
user access.
To increase user privacy, especially with traffic that includes sensitive
information like location and tracking markers, HTTPS should be used
whenever possible. It seems that HTTPS is broken for a lot of sites on
versions older than android-10/Gingerbread, so HTTPS is not used on those
old platforms.
