PX_OWN_ALLOC was intended as a way to disable the use of palloc(), and
over the time new palloc() or equivalent calls have been added like in
32984d8, making this extra layer losing its original purpose. This
simplifies on the way some code paths to use palloc0() rather than
palloc() followed by memset(0).

The basic rule we follow here is to always first include 'postgres.h' or
'postgres_fe.h' whichever is applicable, then system header includes and
then Postgres header includes. In this, we also follow that all the
Postgres header includes are in order based on their ASCII value. We
generally follow these rules, but the code has deviated in many places.
This commit makes it consistent just for contrib modules. The later
commits will enforce similar rules in other parts of code.

pgcrypto already supports key-stretching during symmetric encryption,
including the salted-and-iterated method; but the number of iterations
was not configurable. This commit implements a new s2k-count parameter
to pgp_sym_encrypt() which permits selecting a larger number of
iterations.

Specifically, on-stack memset() might be removed, so:
* Replace memset() with px_memset()
* Add px_memset to copy_crlf()
* Add px_memset to pgp-s2k.c

Backpatch through 8.4.
pgp.h used to require including mbuf.h and px.h first. Include those in
pgp.h, so that it can be used without prerequisites. Remove mbuf.h
inclusions in .c files where mbuf.h features are not used
directly. (px.h was always used.)
