When disconnected a NOTE log entry is made in the log, when connected it just prints which seems inconsistent to me:
```
[2020-06-01T11:50:55] INFO: AES256-GCM-SHA384 TLSv1.2 Kx=RSA Au=RSA Enc=AESGCM(256) Mac=AEAD
/home/jonathan/barrier/src/lib/net/SecureSocket.cpp,872
connected to server
[2020-06-01T11:52:43] INFO: entering screen
```
vs.
```
[2020-06-01T11:59:01] NOTE: disconnected from server
/home/jonathan/barrier/src/lib/barrier/ClientApp.cpp,315
```
Since everything else logs with a timestamp I suggest changing this to NOTE as well for connection events being logged.
QLength() may return 0 even if there are events pending because they
need to be read from the display socket in order to become visible. We
must use XPending() which will poll the socket if QLength() == 0.
This changes the log level for several statuses (started server,
connected to server, server status:) from CLOG_NOTE or CLOG_INFO to
CLOG_PRINT so they will be printed to stdout regardless of the log
level. This allows the GUI to accurately report the status of the
`barriers` or `barrierc` processes in src/gui/src/MainWindow.cpp#L379-L399.
Setting the Fingerprint label to TextSelectableByMouse allows users to
copy/paste the fingerprint so it can be easily added to "TrustedServers.txt"
on a client machine (i.e. via SSH).
Errors where the socket address is in use will keep the server from connecting
with clients. This should be reported as an ERROR instead of a warning. Also,
if the retry time is shorter issues will be more obvious, since the error will
cause the log to scroll visibly.
Silences the "is calling TIS/TSM in non-main thread environment"
messages in the log when running a MacOS server as it is a red herring
that causes a lot of issues to be filed.
The Azure Pipelines MacOS vmImage has an old version of OpenSSL (1.0.2t)
installed at /usr/local/opt/openssl. Normally with Homebrew this directory
would be linked to the currenly installed version of OpenSSL (1.1.x) in
/usr/local/Cellar, but since it has been installed manually here it interferes
with linking libssl.a and libcrypto.a static libraries which causes the build
to fail.
