strptime: fix parsing of tm_year when both %C and %y appear in the

format string in arbitrary order. This makes the related test cases in lib/libc/tests/time (not yet connected to the build) pass. While here, don't error on negative tm_year value based on the APPLICATION USAGE in http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/time.h.html (glibc does the same): tm_year is a signed value; therefore, years before 1900 may be represented.

libc: further adoption of SPDX licensing ID tags.

2017-11-25T17:12:48Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Renumber copyright clause 4

2017-02-28T23:42:47Z

Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point. Submitted by: Jan Schaumann Pull Request: https://github.com/freebsd/freebsd/pull/96

Replace dot-dot relative pathing with SRCTOP-relative paths where possible

2017-01-20T03:23:24Z

This reduces build output, need for recalculating paths, and makes it clearer which paths are relative to what areas in the source tree. The change in performance over a locally mounted UFS filesystem was negligible in my testing, but this may more positively impact other filesystems like NFS. LIBC_SRCTOP was left alone so Juniper (and other users) can continue to manipulate lib/libc/Makefile (and other Makefile.inc's under lib/libc) as include Makefiles with custom options.
