The tzcode package marked it dprecated in the late 1980ies but it is universally supported and here to stay. Triggered by a question from Rodrigo on misc@. William Ahern listed a number of sound arguments why it shouldn't be considered deprecated, in particular that there is no better alternative, in particular none that is thread-safe. While here, fix the non-standard section name "NOTES", add the missing STANDARDS section and provide additional information in the HISTORY section, based on inspection of C89, C11, POSIX 2008, UNIX v4 and v5 at TUHS, Tahoe and Reno at the CSRG archives, amd the SunOS 3.5 and 4.0 manuals on bitsavers. Reasearch on tzcode and SunOS history done by millert@. OK millert@ on an earlier version of this patch, and deraadt@ agrees with the general direction.

value < 0. errno is only updated in this case. Change all (most?) callers of syscalls to follow this better, and let's see if this strictness helps us in the future.
