The build system incorrectly set include directives in AM_CFLAGS which
causes them to be placed after the configured CPPFLAGS. Thus, if
a user or packaging system sets CPPFLAGS to a location that has
libressl or openssl headers installed, they will be used instead
of the bundled versions. This corrects that issue by setting up
the variables correctly.

This moves the compatibility include files from include to
include/compat so we can use the awful MS C compiler
<../include/> trick to emulate the GNU #include_next extension.
This also removes a few old compat files we do not need anymore.
Move define adjustments to CPPFLAGS.
Adjust user CFLAGS directly, do not override during configuration.
USER_CFLAGS is not necessary to build libcompat_noopt correctly.
