Subject: add PTHREAD_NULL
X-Git-Url: http://nsz.repo.hu/git/?a=commitdiff_plain;h=4e0796dfc72f289e97dce3332e6186c6b00b693d;p=musl

add PTHREAD_NULL

this is added for POSIX-future as the outcome of Austin Group issue
599. since it's in the reserved namespace for pthread.h, there are no
namespace considerations for adding it early.
