In https://reviews.freebsd.org/D23418 there is mention of increased
memory usage, from 256K to 77M.  This seems a large increase; was it
looked at in FreeBSD?

The Minix microkernel is one of our supported OSes -- I would keep an
eye on RAM usage so that the project remains usable there.

What is the specific problem that this patch is attempting to address?

<sys/tree.h> would be part of the "libbsd-dev" package in
Ubuntu/Debian ("libbsd-dev" is listed as a build pre-requisite).
