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.

31f5980bd9 Update to upstream version 2.7
The most notable new feature is support for processing multiple
files in one invocation. There is also support for more make-friendly
exit statuses.

The most notable bug fix is #line directives now include the input
file name.

4992d459a5 Add a -o outfile option, which can be used to specify an output file. The
file can safely be the same as the input file.  Idea from IRIX unifdef(1).
This version fixes a bug in the NetBSD unifdef which refuses to
write to a -o outfile which does not exist.

137f2acad4 unifdef: fix invalid array access when nesting limit exceeded
If the number of nested #if blocks exceeds 64, nest() increments
the nesting depth and then reports an error.  The message includes
the line number for the start of the current #if block, which is
read from past the end of the relevant array.

Avoid the out-of-bounds read by reporting the error and exiting
before the nesting depth has a chance to increase.

f6f85e213e Update unifdef to my upstream version 1.188
Main highlights:

(A) The new -B option compresses blank lines around a deleted section
    so that blank lines around "paragraphs" of code don't get doubled.

(B) Lenient evaluation of && and || so that #if expressions can be
    evaluated even when some of their sub-expressions cannot be.

(C) The evaluator can now handle macros with arguments.

(D) Portability fixes, especially for unifdefall.

7dded4a50e Sync with upstream:
Allow the user to run unifdef without defining any symbols. This is
useful in conjunction with the -k flag.
Fix a bug in the -s handling code that would have caused out-of-bounds
array accesses.
Add a -n option to insert #line directives in the output.
Ignore comment markers inside string and character literals
(bug reported by Amos Shapira <amos.shapira@netregistry.com.au>).

eb801906b8 Various fixes from upstream, including a bug...
Fix the usage synopsis.

Amend the copyright notice to reflect the fact that there's no Berkeley
code left.

Fix a typo in a comment, improve the descriptions of the way we use
some global variables (relevant to the bug below), and note that
division-by-zero has side effects so the current expression evaluator
can't be trivially extended to arithmetic in its current design.

Avoid hitting an abort(); /* bug */ when in "text mode" (i.e.
ignoring comment state) by updating the line parser state properly.

0723ff0c6a Sync with upstream again:
* Be less strict about multi-line preprocessor directives (e.g. those
    with comments hanging off the right-hand end) since they're more
    of a problem in practise than I expected. Prompted by phk.

* Fix the handling of "ignore" symbols.

* Style pedantry from OpenBSD and Ted Unangst <tedu@stanford.edu>,
    including some whitespace fixes and removal of strcpy()
    (and not including excessively strict KNF enforcement).

* Fix some typos and terminological inconsistencies.

c284e87d6b Sync with up-stream version, including a number of bug-fixes:
* The partial-evaluation of #elif sequences was broken and the
spaghetti logic of its implementation was too hard to understand.
I've re-done it using a straight-forward table-driven push-down
automaton.

* The pre-processor line parser did not allow for all of the weird
places that people might put comments, which could have caused it
to add syntax-errors to the output by removing a #if line containing
the start- or end-marker of a comment.

* The lexer didn't need to special-case the handling of string-literals
or character-constants, but it did need to learn about line-continuations
(backslash-newline).

* The input routine was buggy and bit-rotten and trivially replacable
with fgets(). I've also made the program static- and const-safe and
improved the presentation-order. The formatting of the state-transition
tables remains non-stylish.

352d0a6932 It is probably a bad idea to unconditionally process directives with
constant controlling expressions: in particular, removing #if 0 sections
is considered "rude". This commit changes the default so that such
things are passed through unchanged, and the old behaviour can be had
with the -k "kill konsts" flag.

3f220dd51a Upgrade unifdef:
* It now knows about the existence of #elif which would have
    caused it to produce incorrect results in some situations.

  * It can now process #if and #elif lines according to the
    values of symbols that are specified on the command line.
    The expression parser is only a simple subset of what C
    allows but it should be sufficient for most real-world
    code (it can cope with everything it finds in xterm).

  * It has an option for printing all of the symbols that might
    control #if processing. The unifdefall script uses this
    option along with cpp -dM to strip all #ifs from a file.

  * It has much larger static limits.

  * It handles nested #ifs much more completely.

There have also been many style improvements: KNF; ANSI function
definitions; all global stuff moved to the top of the file; use
stdbool instead of h0h0bool; const-correctness; err(3) instead
of fprintf(stderr, ...); enum instead of #define; commentary.

I used NetBSD's unifdef as the basis of this since it has received
the most attention over the years.
