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

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.

  -----------
  ovsdb-idlc: Add infrastructure for IDL schema extensions.

An IDL schema is an OVSDB schema with some extra stuff in it.  So far, all
of the extras have been at the top level.  This commit makes it possible
for IDL schemas to have extra information at the table and column levels as
long as it is in an "extensions" member.

No extensions are actually supported yet.

  Log Message:
  -----------
  ovsdb-idlc: Implement synthetic columns.

A synthetic column is one that is not present in the actual database but
instead calculated by code in the client based on columns in the row.  This
can be useful to avoid repeatedly calculating the same function of a row.

  ovn-northd: Reduce amount of flow hashing.

Jakub Sitnicki demonstrated that repeatedly calculating row hashes is
expensive, so this should improve ovn-northd performance.
