userspace/libwr: massive Lindent pass

This is a completely automatic pass, before we start making order
in this library (note: there is a missing semicolon in pps_gen.c:82
but it will be fixed in a later commit -- the bug is in the macro
being called, so the missing semicolon is ok for the compiler).
