  -----------
  [cage] fix PARROT_CANNOT_RETURN_NULL, add HASATTRIBUTE_FORMAT_* variants

* PARROT_CANNOT_RETURN_NULL was empty, thus never detected when used on
  wrong declarations. Implement it now,
  e.g. ./include/parrot/packfile.h:353:9:
  error: returns_nonnull attribute on a function not returning a pointer
* HASATTRIBUTE_FORMAT has multiple variants. try gun_printf, ms_printf
  or printf. Not yet used.
* bring together the definition and it's non-defined counterpart. they are
  currently seperated.  if you add one, you should not forget to add the
  other part.

See GH #1163.

  [cage] add ARGIN_FORMAT decl

which sets  __attribute__format__(n, x) automatically.
x = n+1 when the next arg is ... or otherwise 0.

replace some wrong PARROT_CANNOT_RETURN_NULL with PARROT_WARN_UNUSED_RESULT.

add forgotten PARROT_DEPRECATED, PARROT_EXPOSED as known headerizer macros

add required return value check for the Socket.socket method and use it.

See GH #1163
