doc: Make the age-verification LEGAL-NOTICE more general

Things are changing very rapidly on that front, so rewrote the legal
notice in such a way that it applies based on the existence of an
age-verification law rather than on a list of places and dates.

+# Important notice to residents of places with age-verification laws
+
+As a consequence of recent legislative activity regarding mandatory
+age-verification requirements for operating systems, you may be legally barred
+from using DB48x and its variants due to unimplementable local laws.
+
+* Residents of places implementing such laws may no longer use DB48x
+  as soon and as long as such laws are in effect.
+* Failure to comply with these laws laws will most likely be seen by reasonable
+  people as a truly admirable act of courageous personal civil disobedience
+  against a particularly stupid new form of idiocratic tyranny (also known as
+  tyrannical idiocracy).
+* However, should you or any of your calculator's users be caught using it,
+  the DB48x team will disavow any knowledge of your actions.
+* Under no circumsance should the DB48x team be held legally, morally,
+  physically or otherwisely liable for such admirably heinous heroic acts on
+  your part. Best we can do is cheer and pray.
+
+## Background
+
+Many places have announced or implemented age-verification laws that require
+operating systems to check the age of their users. Such laws are written by
+people with very little technical background, and use terribly vague wording.
+
+As a result of the imprecise wording, one can probably argue that DB48x is an
+operating system under at least a few of these laws. This may not be the intent
+of the law, yet the legal risk exists. Someone, somewhere, may someday consider
+that the words of the law are what matters.
+
+However, DB48x does not, cannot and will not implement age verification. Ever.
+First for obvious technological reasons (obvious at least to any technologist).
+But also on principle. Freedom matters, and it's not chance if all the places
+implementing such laws are on one particular side of the political spectrum.
+
+The authors of the software do not have the legal resources to clarify what
+these laws mean by "operating system", "mobile device", "programming interface",
+or any other weakly defined terminology in the legal text. We are clearly [not
+alone][yc] having trouble with these texts. The team also does not have the
+means to face the stiff penalties outlined in some of the laws, which may amount
+to thousands of dollars per user in some cases.
+
+Consequently, any user who decides to install and run the software must know
+that they became, in application of this notice, the sole local distributor of
+the software. They will need to bear any legal consequences, however unlikely,
+that would derive from this exercise of their fundamental freedoms. If there are
+legal ramification and they don't like them, we invite them to enter a legal,
+judicial or political fight to improve and fix the situation for everyone.
+
+## Blame
+
+Never to be outdone in the real of law innovation, [California][cal] started the
+trend, quickly followed by [Colorado][col], [New-York][ny] and [Brazil][bz].
+Too many other places quickly followed suit, all over the world: bad ideas
+propagate like pest and cholera. As a result, instead of updating this legal
+notice to keep up with the times, it has been rewritten in a way that makes it
+applicable to any place implementing age-verification laws.
+
+[A web site exists][lj] to keep track of the situation.
