APIs in New POSIX Edition

Hi

https://www.opengroup.org/austin/docs/austin_1110.pdf includes a set of new
methods to be added to the POSIX standard. RTEMS has a potential GSoC
student interested in working down the list for RTEMS. Some of these make
sense to be implemented in newlib. All will end up being prototyped in
newlib headers somewhere.

From the document and the formatting is completely lost.

 The additional APIs proposed by participants in the Austin Group that The
Open Group has agreed to sponsor are as follows: dladdr() getentropy()
getlocalename_l() memmem() posix_getdents() ppoll()
pthread_cond_clockwait() pthread_mutex_clocklock()
pthread_rwlock_clockrdlock() pthread_rwlock_clockwrlock() qsort_r()
reallocarray() sem_clockwait() sig2str() str2sig() strlcat() strlcpy()
wcslcat() wcslcpy()

What's the feeling on adding these to the headers? And if OK, what guard
should they be behind?

Thanks.
