This reverts commit 4df19f1b.
It's time to enable the verification.  the packagaes are being
signed since the original commit went in and all tests have
shown that this works as expected.  Staying safe, you know...

prepare for new mvc framework, we use two different document roots in our new setup to separate legacy and new code.

o Do not keep the login error in the session for
  reloading the page without resubmit will yield
  a spurious login error.

o Pad and reword the message and paint it black,
  eh, red.

Javascript went away, caused error, yadda, yadda...

Next step in integrating our new MVC framework, the mainmenu in the left panel uses the same logic now for both legacy as new content.

- add feature, hide empty items
- configuration in /usr/local/opnsense/mvc/app/models/OPNsense/Base/Menu/Menu.xml

(because if you want /var to be an mfs you can do so)

Proxy, ftp added directory tracking and http internal conversion as default for content blocking, work with standard acl list

While there, clean up a little and remove the dysfunct tftp-proxy.
Server part is a little harder, but can be done, too.

We aim to remove non standard kernel hooks to increase maintainability of the project and try to get more connection to standard FreeBSD.

Kernel support is also removed as of 15.1.10.

Most of the stuff it does can be hand-rolled using ifconfig(8).
Since these operations are sparse and well-defined, there's no
harm in doing them.  The added benefit is a quantum leap in
transparency and traceability as well as using a script-based
language to do string manipulation for the command line as
opposed to C-style API fiddling (meaning: it's easier).
