1bcff874c52a changed the behavior of P_RunThinkers() to avoid
dereferencing thinker pointers after they had been freed, but the
modified version of the function was not logically equivalent to
Vanilla version, because the 'next' pointer can be changed by the
thinker function if one is invoked.
This fixes a desync in tnt-speed-movie-0443131.lmp. Thanks to Zvonimir
Bužanić for the bug report and Fabian Greffrath for reporting.
Fixes #547.

Save the next pointer in the P_RunThinkers() loop when iterating through
thinkers, so that if the current thinker is freed we can still advance
to the next thinker without dereferencing freed memory.

... and decrease its value from MAXPLAYERS (i.e. 8) to 4 if
(gamemode == shareware). It seems that it was hard-coded to this value
until some time between the releases of the Demo and the Full version.
Arrays are still declared with their full width of 8, though, they are
just not iterated over the whole range anymore. This fixes playback of
the IWAD demos.

This change rewrites and simplifies the copyright headers at the top
of all source files:
* Remove "Emacs style mode select" line; this line was included in
the headers for the originally released source files and appears
to be to set the file type for old versions of Emacs. I'm not sure
entirely why it was required but I don't think it is any more.
* Remove "You should have received a copy of..." text from copyright
header. This refers to the old 59 Temple Place address where the
FSF headquarters used to be located and is no longer correct.
Rather than change to the new address, just remove the paragraph
as it is superfluous anyway. This fixes #311.
* Remove ---- separator lines so that the file headers are barer
and more simplified.
