ah, forgot something ..

A benefit for transforming the global mempool to memfds by
default now is that a follow-up patch can be quickly developed
to statically remove POSIX SHM support through a
--disable-posix-shm configure flag.

Doing so, we can build a memfd-only libpulse version that can be
bundled in xdg-app runtimes going forward .. [1] [2]

If this is deemed not too high a priority and the danger from
any statically-linked or bundled libraries is higher, then let's
merge patches #1 to #10 and I'll later post a modified version of
patch #11 that only transforms the srbchannel mempool to memfds.
