Fix online installation into directory with elevated permissions.

Inside the Resource class we can't use QFile, as that will access
the elevated running server to read from a only client side mapped
file. Adjust Resource::readData to behave properly with the file
engine's nativeRead(...) implementation, e.g. on Unix it returns
-1 if called to read with a size of 0 bytes.
Do not write to the socket if we are running in a different thread
than the one the socket was created in. Fix logically broken connect
function.
