Remove experimental/Networking code

Bug: chromium:1101491
Bug: b/161896447

The motivation here was to remove uses of the word "master". But this
code is in experimental/, and it doesn't look to be used (based on
code searches in Chromium, Android, and Google3). The last meaningful
changes were in 2011; other changes have just been upkeep.
