 Make PTHREAD_KEYS_MAX dynamically adjustable
 NetBSD's PTHREAD_KEYS_MAX is set to 256, which is low compared to
 other systems like Linux (1024) or MacOS X (512). As a result some
 setups tested on Linux will exhibit problems on NetBSD because of
 pthread_keys usage beyond the limit. This happens for instance on
 Apache with various module loaded, and in this case no particular
 developper can be blamed for going beyond the limit, since several
 modules from different sources contribute to the problem.
 This patch makes the limit conigurable through the PTHREAD_KEYS_MAX
 environement variable. If undefined, the default remains unchanged
 (256). In any case, the value cannot be lowered below POSIX-mandated
 _POSIX_THREAD_KEYS_MAX (128).
 
 While there:
 - use EXIT_FAILURE instead of 1 when calling err(3) in libpthread.
 - Reset _POSIX_THREAD_KEYS_MAX to POSIX mandated 128, instead of 256.
 
 Fix previous: Can't use calloc/malloc before we complete initialization
 of the thread library, because malloc uses pthread_foo_specific, and it will
 end up initializing itself incorrectly.
 
 Thanks rump for not letting us use even mmap during initialization.
 
 libc/jemalloc:
 
 Fix non _REENTRANT build.
 Defer using pthread keys until we are threaded.
 From Christos, fixes PR port-arm/50087 by allowing malloc calls prior
 to libpthread initialization.
