disallow eval { goto &foo }
eval 'goto &foo' is already banned, and the try-version usually
coredumps due to the code assuming the CxEVAL is actually a CxSUB.
Anyway exiting an eval but preserving "it's" @_ doesn't make much
sense.

Fix [perl #35929] : PerlIO::scalar didn't understand $/ = ""
because PerlIOScalar_unread was broken.
Bump version number of PerlIO::scalar to 0.04.
