This allows developers to build and run the extension by default.
Official packages bundles will be re-signed after the build, we
The SocketApi prefix can be set at configure time through cmake and
should match the key that will be used to sign the whole .app bundle
(including the embedded FindexSync .appex bundle).
This prepares the switch to the official FinderSync API on Yosemite
which requires the extension to run in a sandbox. This complicates
the usage of a local socket to communicate with a non-sandboxed GUI
client. An NSConnection is easier to use in this case, which we can
use as long as the server name (i.e. Mach port registered name) is
prefixed with the code signing Team Identifier.
A placeholder server implementation is also added to the client's
SocketApi which basically reproduces the interface of a QLocalSocket.
Most of the references to individual sockets we're only using
QIODevice methods so the type was simply reduced. A typedef to
replace the QLocalServer was the only other part needed.
removeIcons isn't called and clearFileNameCacheForPath was always
called with a "nil" path.
Remove the return value of askForIcon which was always 0, and use
that value explicitly at the only call site.
Remove the "-1" code path in iconByPath since setIcons prevents
-1 from getting into _fileNamesCache in all cases.
