The ODP_DEPRECATED macro uses the deprecated attribute which works only
for types and functions, but not e.g. for fields of structure. So let's
add ODP_DEPRECATED_FIELD macro suitable for fields, variables and enum
values.
Also make ODP_DEPRECATED{,_FIELD} macros to be a no-op if
ODP_ALLOW_DEPRECATED is defined. ODP code MUST be compiled with this
macro, so that it supports deprecated API. Examples SHOULD be compiled
without this macro defined, so that they show best current practice of
using API but still MAY use the macro untill particular application is
ported to new API. User applications SHOULD try to compile without
ODP_ALLOW_DEPRECATED macro defined.
