Convert usr.sbin to LIBADD
Reduce overlinking

Add -Wthread-safety to WARNS=6.

While there, add a NO_WTHREAD_SAFETY flag that can be used to disable
this specific warning flag. Disable it for auditdistd. We can easily
patch up auditdistd to have the right annotations to build, but as
auditdistd is intended to be portable across other operating systems,
it's not worth the effort.

Add the Clang specific -Wmissing-variable-declarations to WARNS=6.

This compiler flag enforces that that people either mark variables
static or use an external declarations for the variable, similar to how
-Wmissing-prototypes works for functions.

Due to the fact that Yacc/Lex generate code that cannot trivially be
changed to not warn because of this (lots of yy* variables), add a
NO_WMISSING_VARIABLE_DECLARATIONS that can be used to turn off this
specific compiler warning.

Announced on: toolchain@

Merge a number of changes required to hook up OpenBSM 1.2-alpha2's
auditdistd (distributed audit daemon) to the build:

- Manual cross references
- Makefile for auditdistd
- rc.d script, rc.conf entrie
- New group and user for auditdistd; associated aliases, etc.

The audit trail distribution daemon provides reliable,
cryptographically protected (and sandboxed) delivery of audit tails
from live clients to audit server hosts in order to both allow
centralised analysis, and improve resilience in the event of client
compromises: clients are not permitted to change trail contents
after submission.
