[RFC PATCH] tests/tcg: update licenses to GPLv2 as intended

[RFC PATCH] tests/tcg: update licenses to GPLv2 as intended

[Alex Bennée]

My default header template is GPLv3 but for QEMU code we really should
stick to GPLv2-or-later (allowing others to up-license it if they
wish). While this is test code we should still be consistent on the
source distribution.

I wrote all of this code so its not a problem. However there remains
one GPLv3 file left which is the crt0-tc2x.S for TriCore.

Test code, and more importantly not linked against
QEMU proper -- it's all standalone guest binaries,
so we don't link this code with any GPL-v2-only code.

Of these files, contributions by somebody other than Alex:

tests/tcg/multiarch/float_convd.c
tests/tcg/multiarch/float_convs.c
tests/tcg/multiarch/float_helpers.h
tests/tcg/multiarch/float_madds.c
 Richard Henderson <richard.henderson@linaro.org>
which is all Linaro copyright.

tests/tcg/multiarch/libs/float_helpers.c
 Taylor Simpson <tsimpson@quicinc.com>
 ...but this was exclusively deleting lines

plus a couple of typo/spelling fixes from
Michael Tokarev <mjt@tls.msk.ru> which I don't think rise
to the level of being relicensable contributions.

So I don't think we need anybody else's signoff for this
relicensing.

thanks
