David Pursell 3f902aad5b adb: relax serial matching rules.
Currently targeting a device by serial requires matching the serial
number exactly. This CL relaxes the matching rules for local transports
to ignore protocol prefixes and make the port optional:
  [tcp:|udp:]<hostname>[:port]

The purpose of this is to allow a user to set ANDROID_SERIAL to
something like "tcp:100.100.100.100" and have it work for both fastboot
and adb (assuming the device comes up at 100.100.100.100 in both
modes).

This CL also adds some unit tests for the modified functions to make
sure they work as expected.
