Clean-up: Remove pthread and mutex locking code

This code was not activated at all, and hard coded as disabled in syshead.h
with this code snippet:

   /*
    * Pthread support is currently experimental (and quite unfinished).
    */
   #if 1 /* JYFIXME -- if defined, disable pthread */
   #undef USE_PTHREAD
   #endif

So no matter if --enable-pthread when running ./configure or not, this feature
was never enabled in reality.  Further, by removing the blocker code above made
OpenVPN uncompilable in the current state.

As the threading part needs to be completely rewritten and pthreading will not be
supported in OpenVPN 2.x, removing this code seems most reasonable.

In addition, a lot of mutex locking code was also removed, as they were practically
NOP functions, due to pthreading being forcefully disabled
