deleted copyright definition and entity transactions provision

In 2006 lawyers for Sun Microsystems suggested adding an explicit
definition of "copyright" that would encompass not just conventional
copyright law but also laws like the US Semiconductor Chip Protection
Act (which is something of a hybrid of copyright and patent law). The
application of the GNU GPLv3 to semiconductor integrated circuit
layouts proved to be an unimportant use case. No other
widely-encountered free software license attempts explicitly to apply
its provisions beyond copyright to such "copyright-like laws". In the
interest of brevity I have therefore deleted this definition.

I have deleted the middle paragraph of section 10, the "entity
transactions" provision. This originated in a provision drafted by
Eben Moglen as an alternative to a suggestion by Mark Radcliffe that
GPLv3 have an explicit assignability provision to address a concern
believed by some lawyers to arise in corporate acquisitions involving
GPL-licensed software assets. I am currently inclined to regard Mark's
concern as not being a real-world problem, and perhaps unnecessary
given the automatic licensing feature of the GPL but at any rate I
consider a simple conventional assignability provision preferable to
the existing entity transactions provision, which seems more complex
than necessary. It is not clear how the "right to possession of the
Corresponding Source" is to be enforced (it might be simpler to say
that an entity transaction is a form of conveying, and in fact I seem
to recall some interim GPLv3 draft language taking such an
approach). In any case, this is yet another provision that finds no
counterpart in other major free software licenses. In the interest of
greater brevity it should be deleted, but the issue of assignment in
the M&A context should perhaps be revisited at a later time.
restored original name of present-day sec. 12

What is now section 12 of GPLv3 (the successor to GPLv2 section 7)
bore the heading "Liberty or Death for the Program" in the initial
public draft of GPLv3. The heading was, I believe, devised by
RMS. This wonderful title was, I think, thought to be too
radical-sounding or something (perhaps a vendor or commercial user
raised such a concern early on during the GPLv3 drafting process), and
so the drafters changed it to "No Surrender of Others' Freedom". The
original heading is clearly superior. I have myself taken to calling
this provision the "liberty-or-death clause" and such terminology has
to some degree caught on with others.

In fairness, I recall that RMS also made the point that under this
provision the Program does not actually "die"; rather, particular
copies of it may become nondistributable. Thus the heading was never
truly accurate.  But the principal reason for this change was
lamentable primness.

I have therefore restored the original heading.
deleted obvious clarification of definition of licensee

This commit deletes the sentence, originating in some interim GPLv3
draft at the request of one (or possibly more than one) commercial
entity, clarifying that licensees can be individuals or
organizations. No other mainstream free software license, to my
knowledge, has seen the need to make this obvious point. Of course a
licensee can be organizational. Moreover, I have never encountered any
misconception in the real world to the effect that somehow GPL
licensees can only be natural persons. Indeed, any license that
prohibited organizations from being licensees would not be a free
software (or open source) license.
de-defined License Steward

This commit explicitly leaves "License Steward" undefined rather than
making it refer, with seeming and unintended egomaniacism, to Richard
Fontana.  Whether it is even necessary to use the "License Steward"
vehicle is something that should be revisited, but for now it is a
placeholder that replaces the stewardship role given to the FSF in the
GNU GPL.
