WSJT-X/soundin.h
Bill Somerville 5eb5735168 Rearranged sequencing of audio streams and devices.
The code  was starting streams linked  to closed devices which  may be
causing issues on  the Mac version.  I have refactored  to ensure that
devices are always opened before related audio streams are started.

Made .h C++ headers emacs friendly.

Removed some code in the MainWindow  contructor that read the log file
but failed to check if the file exists and didn't do anything with the
data anyway.
