  1. Add hash_make macros 

    This adds a bunch of hash_make* and shmem_hash_make* macros to make it
easier and less error prone to create HTABs. These macros are
implemented as wrappers around the already existing hash_create
function. Using the new macros is preferred, due to the additional
compile time checks that they bring.

  2. Use hash_make macros throughout the codebase 

    This shows how our code base looks when using the new APIs. This has
some typesafety, readability and maintanability benefits, but it also
introduces some backpatching problems. These backpatching problems
cannot be resolved by backporting the new hash_make macros, because some
of them require C11 (which we only require on master for now). I think
it's unlikely that we'll need to backpatch things in code that creates
hashtables though, so it could still be worth it to do this complete
refactor.

At the very least we should choose a few places where we use the new
macros to make sure they have coverage.

  4. Add foreach_hash macro 

    For lists we've had a new foreach style macros since 14dd0f2. This
adds a similar macro for hash tables. This new foreach_hash macro makes
iterating over the items in an HTAB as simple as iterating over the
items in a List. The only additional thing to keep in mind is that when
exiting the loop early you need to call foreach_hash_term.

  5. Use foreach_hash macro throughout the codebase 

    This starts using the new foreach_hash macro throughout the codebase.
This makes code easier to read, but obviously does introduce
backpatching problems. We can choose not to do this refactor to avoid
that. Or we could instead choose to do the refactor and then backpatch
these new macros so they can be used in backpatched code.

At the very least we should choose a few places where we use the new
macros to make sure they have coverage.

  6. [CF 6276] v3 - Safer hash table initialization macro 

    This branch was automatically generated by a robot using patches from an
email thread registered at:

https://commitfest.postgresql.org/patch/6276

The branch will be overwritten each time a new patch version is posted to
the thread, and also periodically to check for bitrot caused by changes
on the master branch.
