Use __FBSDID instead of the license agreement to embed the $FreeBSD$ RCS keyword Reminded by a comment made by markj w.r.t. using __FBSDID in .c files ala a past Phabricator review.

sbuf(3): add some basic functional tests for the library Areas not covered still [positive functionality wise] are: - sbuf_{clear,get,set}_flags - sbuf_new (in particular, with fixed buffers, etc). Some basic negative testing has been added, but more will be added in the future. This work was in part to validate work done by cem in r288223, and ian before that.

r307873 (by marcel): Include instead of when compiled as part of libsbuf. The former is the standard header, and allows us to compile libsbuf on macOS/linux. r314397 (by scottl): Implement sbuf_prf(), which takes an sbuf and outputs it to stdout in the non-kernel case and to the console+log in the kernel case. For the kernel case it hooks the putbuf() machinery underneath printf(9) so that the buffer is written completely atomically and without a copy into another temporary buffer. This is useful for fixing compound console/log messages that become broken and interleaved when multiple threads are competing for the console. r314399 (by scottl): Add prototype for sbuf_putbuf() r314419 (by jkim): Include stdio.h to fix libsbuf build. r314420 (by scottl): Provide a comment on why stdio.h needs to be included. r314533 (by scottl): Expose the sbuf_putbuf() symbol to libsbuf. There are a few other symbols that are present but not exposed, like get/set/clear flags, not sure if they need to be exposed at this point. r316553: sbuf(3): expose sbuf_{clear,get,set}_flags(3) via libsbuf These functions were added to sbuf(9) in r279992, but never exposed to userspace. Expose them now so they can be used/tested.

r312452-r312512: - Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones This simplifies pathing in make/displayed output - Use .CURDIR:H instead of .CURDIR to simplify pathing in output, etc

First pass through library packaging.

META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.

2015-11-25T19:10:28Z

This both avoids some dependencies on xinstall.host and allows bootstrapping on older releases to work due to lack of at least 'install -l' support. Sponsored by: EMC / Isilon Storage Division

Enforce overwritting SHLIBDIR

2015-06-15T15:34:20Z

Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere. This makes /lib being populated again. Reported by: many
