Fix an error while building test_radixtree.c with TEST_SHARED_RT

because it eventually sets RT_SHMEM when #include'ing radixtree.h but
it's missing some header files to include. I've attached a patch to
include necessary header files in radixtree.h to make it
self-contained.

+1. Please make sure the #includes are in alphabetical order.

While we're at it, I noticed that lib/radixtree.h includes "postgres.h".
That's against our usual convention.

Fixed.

Good catch. I've updated the patch accordingly.

Probably out of scope for this particular patch, but it occurred to me
to grep for other similar violations, and I found three:

src/bin/pg_combinebackup/copy_file.h:#include "c.h"
src/include/fe_utils/option_utils.h:#include "postgres_fe.h"
src/include/fe_utils/query_utils.h:#include "postgres_fe.h"

If those includes are only needed when RT_SHMEM is defined, I suggest
they should be guarded by #ifdef RT_SHMEM, per Peter E's IWYU efforts
lately.

Good catch, make sense to fix them too. Probably we can fix them
including the removal of inclusion of postgres.h from radixtree.h in
one commit, and fix the inclusion issue in radixtree.h in another
commit.

Indeed. I'll incorporate it in the next version.

I've attached the updated patches. Please review them.

I think we should backpatch the fix for radixtree.h so I kept these
changes separated from other changes.
