[Cin] fileffmpeg.C history digging

[Andrew Randrianasulu]

So, it seems file was already present in CinHV 4.0 from around aug 2008

https://sourceforge.net/projects/heroines/files/releases/081108/cinelerra-4-src.tar.bz2/download

same file present in 4.1

So I guess Monty only noticed it in 4.1 because 4.0 was  "hiding" in
081108 folder.

this specific archive does not show exact date, but I guess 12 years
ago will give us 2010 or so

sooo ... I think correct author lines will be
1) Adam's (c) 2008
2) Monty's (c) 2010
3) Paolo Rampino (2012-2014)
4) W.P.Morrow (2015-2020)

3) based on https://github.com/cinelerra-cv-team/cincv-exp-akirad-paolo/commits/master/cinelerra/ffmpeg.C

4) based on
https://code.google.com/archive/p/cinelerra/source/default/commits?page=2
"Good1.2Guy 2015-02-20 11:21:11 -0700 bf3a568a7ce3 CV file codec mods
+ a few fixes
"

bootstrap.c seems to be part of CinCV build system since initial commit in 2003:
https://github.com/cinelerra-cv-team/cinelerra-cv/commit/696d7a41ec6bc52473872c8657bfccfc1e6554b6#diff-976ce94ba53051b26dde9523cdaa59891f4d931088a35172db3ce4d1ddda2e5a

Because fileffmpeg.c/ffmpeg.C history is very convolved may be we
should put 'evidence' links in header too? (because current CinHV
fileffmpeg says 2016-2022 by Adam, I guess it was rewrite of 2008 code
..?)
