Add envz_remove to the libc manual
I was told that Ma Shimao submitted a patch to add envz_remove to the libc manual, but the patch could not be accepted since he does not have a copyright assignment in place. I have been woefully behind on libc-alpha recently and have not seen the patch or the discussion thread. I have also not read the man page for envz_remove, so Alexandre Oliva asked me if I could write this independently and post a patch. The patch below is the result of the same - I have written it based on the implementation in string/envz.c and Alex told me via email that the function is AS, AC and MT-safe like envz_strip. I assume Alex and Carlos cannot review this since they have been tainted by the original patch (I haven't even tried to look for a link to it since I don't want to be tainted) so someone else will have to review this. If there are no reviewers till the end of the week, I will commit this since I believe there is a chance that there are no other reviewers who haven't read that thread. * manual/string.texi (Envz Functions): Add envz_remove.
