We don't particularly need this code and the utility as netgraph
is always attached on load as long as we don't detach and the
attach per interface is a custom feature that requires a kernel
patch we don't want to keep around for 17.1.

Only thing we need to measure is the performance impact of not
detaching netgraph.  This only pertains to ethernet devices
anyway.

We do, however, keep interface_netgraph_needed() around for
reference as it's harmless by default.

LDAP fix: handle legal boolean return result from searchUsers()

Carp improvements

The old script had a lot of unused code in it, either stuff that couldn't be configured from OPNsense or dead code.

Revert "(ids) style fix", https://github.com/opnsense/core/commit/aaa0ddafe1179cebc68146bdc3c30b8b90c564b8 can cause "Allowed memory size of ... bytes exhausted", better to set a sane default max here.

This reverts commit aaa0ddaf.

(firmware) add configd "firmware loader" commands to control the contents of /boot/loader.conf.local

plugins can use this call to register new bootup parameters, new commands added:

configctl firmware loader show
configctl firmware loader rm <parameter>
configctl firmware loader edit <parameter> <value>
