In r268463, I misplaced a return in demangle(), causing the function to
erroneously skip symbols that were not mangled at all.  Fix this by
moving the return into the preceding if block.

While here, simplify the code by letting __cxa_demangle() allocate the
needed space for the demangled symbol.  This also fixes a memory leak,
which would occur whenever __cxa_demangle() failed.

Small modification of the sctp_input() cleanup to avoid having
code between declariations.
When r255294 was committed, it exposed the symbols lgammal, powl,
and tgammal in libm.  These functions are part of ISO/IEC 9899:1999
and their prototypes should have been moved into the appropriate
__ISO_C_VISIBLE >= 1999 section.  After moving the prototypes,
remnants of r236148 can be removed.
