v1.0.0

 * patch-aj and patch-ak prevent the software from miserably failing when a
   user does not have CAP_SYS_NICE. This is merely required to set the
   scheduling parameters of threads, and this should not be fatal.
   Just print a warning instead.

 * update patch-ai to compile object files with -fPIC. This won't hurt when
   linked in an executable, and it is required whenb link this library in a
   another shared library.

 * Fix unzip extraction by forcing -aa, so that CR/LF is converted
   correctly. Updated all patches accordingly
