Update to 0.14.3 and rearrange GOPATH and build layout

Update to 0.14.3; this is a new major version with an incompatible
protocol.  It has been tested with syncthing-android 0.8.1.

Redo build layout, so that the sources are placed at the path
recommended by upstream.  Reduce the number of symlinks used to get go
building to work.

Upstream changes:


v0.14.3: 3 bugfixes
v0.14.2: 1 bugfix
v0.14.1: 1 bugfix and
  This release includes "delta indexes", a backwards compatible protocol
  enhancement. Prior to delta indexes being implemented, full index
  information was exchanged at every connection start. With delta
  indexes, only index information that has changed since last contact is
  transferred. Delta indexes are enabled automatically between 0.14.1+
  devices.
v0.14.0: many bugfixes and
  This is a new major release, incompatible with Syncthing v0.13 and
  earlier.  This release introduces a new, extensible sync protocol
  and corresponding changes to local discovery and the database.  The
  sync protocol, local discovery protocol and database format is now
  based on protocol buffers.
