Fixed problems in optstring passed to getopt_long(). Some of the options that take no argument were listed as taking an argument.
Disable buffering of stderr too when --unbuffered is specified.
Don't load symbols from dynamic libraries at startup. If we do executables built with RoboVM take ages to start.
Fixed type in options (gbdargs => gdbargs).
Proper output of ds_path and img_path when verbose=true.
Removed all loading of shared libraries to speed up gdb startup.
Disabled uuid check of shared libs.
