ovsdb-idlc: Add "cDecls" and "hDecls" IDL schema extensions.

Browse Source 
An IDL schema is an OVSDB schema with some extra stuff in it: an idlPrefix
and an idlHeader at the top level to indicate what ovsdb-idlc needs to
generate the interface definitions.  This commit adds support for two more
optional IDL schema extensions that allow extra code to be written to the
.c and .h file that ovsdb-idlc generates.
