Leaf directories that have dependencies impacted
by options need a Makefile.depend.options file
to avoid churn in Makefile.depend
DIRDEPS for cases such as OPENSSL, TCP_WRAPPERS etc
can be set in local.dirdeps-options.mk
which can add to those set in Makefile.depend.options
See share/mk/dirdeps-options.mk

We were not adding CAP_EVENT to input file capabilities, so kevent()
always failed with ENOTCAPABLE. tail implements a fallback mode to
poll the file in this case, so the failure was not apparent.

The freopen(3) was replaced with fileargs_open(3) and fclose(3).
In the following function, we skip if the stream is standard in, so it is
safe to do so.
This also requires us to change the logic first to open the file and then
check its status. The stat(2) is disallowed in capability mode.
This commit unbrakes the -F option.
The bug was introduced in the r348708.

Add --blocks, --bytes, and --lines long options for -b, -c, and -n
respectively. This improves tail(1)'s compatibility with its GNU counterpart
in a straightforward way.

A subtle logic bug, probably introduced in r311895, caused tail to print the
first two lines of piped input in forward order, if the very first character
was a newline.

Mainly focus on files that use BSD 3-Clause license.
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.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
- Capture exit code in pipeline and test in output.
- Drop awk use in favor of `sleep 2`. This helps guarantee the EPIPE
behavior without the potential race.
In the case where write(2) does not return -1, it does not initialize errno.
This can happen when a broken pipe causes a short write.
I attempted to adapt the submitted test case to ATF but could not figure out
how to make the test run in the ATF environment. So the aborted test is
left disabled, in case someone would like to run it manually or fix it.

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.

* Rewrite r_buf to use standard tail queues instead of a hand-rolled
circular linked list. Free dynamic allocations when done.
* Remove an optimization for the case where the file is a multiple of 128KB
in size and there is a scarcity of memory.
* Add ATF tests for "tail -r" and its variants.

Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.
Still need to add real targets under targets/ to build packages.

If tail notices that a file it is following no longer exists (because stat()
fails), it will output any final lines and then close the file. If the read
operation also causes an error, such as when the filesystem is forcefully
unmounted, it closes the file as well, leading to fclose(NULL) and a
segmentation fault.

trying to open files rather than giving up when it encounters an
error. ENOENT errors are not reported.
As a result, files that are moved away then recreated are not at
risk of being 'lost' to tail. Files that are recreated and
temporarily have unreadable permissions will be shown when they
are fixed.
This behaviour is consistent with the GNU version of tail but
without the verbiage that goes with the GNU version.
This change also fixes error messages accompanying -f and -F.
They no longer report problems with (null)!
