[Patch, Fortran] PR 47023: C_Sizeof: Rejects valid code

[Janus Weil]

Hi all,

here is another patch for PR47023, which takes care of comment #1,
i.e. rejecting polymorphic variables in a C-binding context. It also
adapts two functions (verify_c_interop,verify_c_interop_param) to the
gfortran naming convention of prefixing public routines with 'gfc_',
and fixes an error message which had incorrect wording. The only
nontrivial part of the patch is in decl.c (the rest is just renaming).

Regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
