1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified 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.

No functional change intended.

93b09f581a Remove badsect(8).
Failure modes of the modern (that is, produced in the last 25 years)
hard drives and SSDs made the utility outdated.  Since the kernel
interface to support it was removed in r324853, cut the userspace
remnants as well.

4572fb3faf Deorbit catman. The tradeoff of disk for performance has long since tipped
in favor of just rendering the manpage instead of relying on pre-formatted
catpages. Note, this does not impede the ability to use existing catpages,
it just removes the utility to generate them.

f513dfd44b crunchide: report explicit error for combined string table
Some tools produce objects with a combined strtab and shstrtab.
These objects are not supported by crunchide since it rewrites the
symtab and strtab to "hide" symbols. This invalidates section header
offsets into a combined strtab/shstrtab.

In the future we could support these objects (by ensuring that we retain
unmodified section name strings in the output .strtab, and then rewriting
each section header's sh_name).

5017231ad7 META_MODE/DIRDEPS_BUILD: Fix various issues with crunch builds.
- DIRDEPS_BUILD: Fix crunchgen builds losing their library dependencies
  on a nop-rebuild.
- META_MODE: Fix not rebuilding various crunch.mk targets if their .meta
  files warrant a rebuild.  They were lacking .meta files previously.
  This adds .NOMETA to the crunch objects being used since they are
  already built.  Bmake was forcing a rebuild on them since their
  .meta files were not in the expected place; there is no reason to
  rebuild them.

eb9b07bb77 WITH_AUTO_OBJ: Fix crunchgen builds.
Passing MAKEOBJDIRPREFIX to the main prog build (rescue) would confuse
WITH_AUTO_OBJ and cause it to create a recursed object directory that
then broke the actual prog build.  This is normally not a problem since
we do not call 'make -f prog.mk obj' before building anything in it.

Crunchgen(1) also assumes that if -o is not passed then if an object
directory does not already exist then it should build in the source
directories.  The normal buildworld process will have already ran 'make
obj' in each of the component directories so this is not a problem.
With WITH_AUTO_OBJ though this is not the case.  So we must tell
crunchgen(1) that MK_AUTO_OBJ=yes will create the directory and to not
require it be present before generating its Makefile.

5608fd23c2 Revert r267233 for now. PIE support needs to be reworked.
1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other
   build-only utility libraries.
2. Another 40% is fixed by generating _pic.a variants of various libraries.
3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR)
   where it never would work anyhow, such as csu or loader. This suggests
   there may be better ways of adding support to the tree. Many of these
   cases can be fixed such that -fPIE will work but there is really no
   reason to have it in those cases.
4. Some of the uses are working around hacks done to some Makefiles that are
   really building libraries but have been using bsd.prog.mk because the code
   is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have
   been needed.

We likely do want to enable PIE by default (opt-out) for non-tree consumers
(such as ports). For in-tree though we probably want to only enable PIE
(opt-in) for common attack targets such as remote service daemons and setuid
utilities. This is also a great performance compromise since ASLR is expected
to reduce performance. As such it does not make sense to enable it in all
utilities such as ls(1) that have little benefit to having it enabled.

864c53ead8 In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.
This is currently an opt-in build flag. Once ASLR support is ready and stable
it should changed to opt-out and be enabled by default along with ASLR.

Each application Makefile uses opt-out to ensure that ASLR will be enabled by
default in new directories when the system is compiled with PIE/ASLR. [2]

Mark known build failures as NO_PIE for now.

The only known runtime failure was rtld.

The crunchide utility presumes the last 3 chunks of an ELF object
layout are section headers, symbol table, and then string table.
However, this is  not specified in the ELF standards, and linkers
may generate different layouts when doing partial linking (-r).

This change is required to build FreeBSD with mclinker or the
gold linker.
