Its possible poll() will return that a socket is both readable and
writable. When this happens TCPSocket::serviceConnected() is
overwriting the result from doWrite() with the result from doRead()
This can cause a situation where doWrite() tried to notify that we
should stop polling if the socket is writable, but the doRead() result
causes that to be ignored. This results in a tight loop and 100% cpu
usage in SocketMultiplexer::serviceThread() as the poll() call
instantly returns that the socket is writable, but no one cares that
it is. The issue eventually corrects itself with enough mouse
movement/clicks.
Adds the [preserveFocus configuration](https://github.com/symless/synergy-core/wiki/Text-Config#Focus_Preservation) item to the GUI configuration screen.
This is useful if you want to control a system that you are not the only user of. For example, I use barrier to control my HTPC computer sometimes, but I don't want Kodi to lose focus when my cursor leaves the screen since it will cause other inputs (i.e. CEC Remote) to stop working.
* make waitForTray() report a proper status - the return value was not
used until now anyway (it would always return true)
* depend on the system tray availability for auto hide
On my system (Fedora 29 with Pantheon Desktop), on a clean install the GUI
would auto hide itself on startup, but due to no system tray being
available I could never make the GUI appear again.
This change disallows auto hide if the system tray is not available.
Users who don't want the GUI can just start barriers/barrierc instead of
the main barrier executable, so this should not break existing workflows.
I build barrier on windows from SSH, as such, I need a way to invoke the "Developer Command Prompt for VS 2017" without a GUI. This simple one-line batch script gets the job done. I thought it might be handy to upstream it.
process I use to build on windows:
```shell
$ ssh owner@10.0.0.209
owner@DESKTOP-C2IV8E5 C:\Users\Owner> cd Documents\GitHub\barrier\
owner@DESKTOP-C2IV8E5 C:\Users\Owner\Documents\GitHub\barrier> pre-build.bat
owner@DESKTOP-C2IV8E5 C:\Users\Owner\Documents\GitHub\barrier> clean_build.bat
```
Done in order to match the size specified in src/gui/src/SslCertificate.cpp
