Fedora uses /usr/lib64 on 64-bit systems. Allow easy configuration in cmake to install to correct directories.
This resolves joan2937#455 with the discussion with @guymcswain that gpioCfgSetInternals() should return an error if gpioInitialise() has been called previously to report that it's no longer possible, for example, to disable signal handling. If successful it returns 0 as before. Tested it by calling gpioCfgSetInternals, gpioInitialise, gpioCfgSetInternals and reports 0 and -32 which looks OK.
Fixed the documentation that the command set_PWM_range() actually returns the actual range. This resolves joan2937#453.
gpioCfgSetInternals now returns PI_INITIALISED after gpioInitialise
Allow building on 64-bit system using lib64

Unix-domain sockets have less overhead than TCP.
They also tend to work better on a system that's built without networking. ;-)
