The intention is to lower the value of the pointer, which according to ubsan
cannot be done by adding an unsigned quantity.

This fixes the build and I will redo these changes as part of a future review
that organizes them differently. The way I tried to do it here could be done
better. Sorry for the noise.

This moves the symlink creation to after where the files are installed.
This also inverts the shell change so that it only happens if MK_TCSH is on.

This simplifies pkgbase by migrating these to CONFS so they are properly
tagged as config files.

Using padvance() requires undoing its append of '/' and prevents adjusting
its '%' logic to allow most directories with '%' in PATH.
No functional change is intended.
These are not used to link the final tool anymore. At some point in the past
the suffix rules changed to not link these in. The original reason for this in
r19176 is unclear but seems to be related to mkdep. The .depend handling is
still broken here as it is for all build tool patterns like this.

POSIX requires accepting unquoted newlines in word in parameter expansions
like ${param+word}, ${param#word}, although the Bourne shell did not support
it, it is not commonly used and might make it harder to find a missing
closing brace.
It was also strange that something like
foo="${bar#
}"
was rejected.

It won't work e.g. when crossbuilding from Ubuntu Linux as mktemp is in
/bin there.

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.
Non-tests/... changes:
- Add HAS_TESTS= to Makefiles with libraries and programs to enable iteration
and propagate the appropriate environment down to *.test.mk.
tests/... changes:
- Add appropriate support Makefile.inc's to set HAS_TESTS in a minimal manner,
since tests/... is a special subdirectory tree compared to the others.

Apart from the fact that subtle syntactic changes make a poor compile-time
option, the NOHACK case has been obviously broken since it was added,
because it uses q uninitialized if (*p != '\0').
No functional change is intended.
If CDPATH is used non-trivially or the operand is "-", cd writes the
directory actually switched to. (We currently do this only in interactive
shells, but POSIX requires this in non-interactive shells as well.)
As mentioned in Austin group bug #1045, cd shall not return an error while
leaving the current directory changed. Therefore, ignore any write error.
Starting the fc -e editor can execute arbitrary script, and executing
arbitrary script with INTOFF in effect may cause unexpected results.
This change (together with other changes) serves mainly to allow asserting
that INTOFF is not in effect when starting the evaluation of a node.
Allocating and deallocating repeatedly the 1024-byte buffer for stdout from
builtins costs CPU time for little or no benefit.
A simple loop containing builtins that write to a file descriptor, such as
i=0; while [ "$i" -lt 1000000 ]; do printf .; i=$((i+1)); done >/dev/null
is over 10% faster in a simple benchmark on an amd64 virtual machine.
Similarly to how STPUTC was changed, change struct output to store the
pointer just past the end of the available space instead of the size of the
available space, so after writing a character it is only necessary to
increment a pointer and not to decrement a counter.
It does not make much sense to generate the '-' in a pattern bracket
expression using arithmetic expansion, but it does not make sense to forbid

Try to avoid reprocessing the string if it is unnecessary.

This test already passes.
The special case of modifying an existing alias does not work correctly if
the alias is currently in use. Instead, handle this case by unaliasing the
old alias (if any) and then creating a new alias.
