Fix unbound remote denial of service vulnerability.

Security: FreeBSD-SA-14:30.unbound
Security: CVE-2014-8602
Approved by: so

Remove svn:mergeinfo from the releng/10.0 branch.

After branch creation from stable/10, the stable/10 branch mergeinfo
was moved to the root of the branch.

Since there have not been any merges from stable/10 to releng/10.0
yet, we do not need to track any of the existing mergeinfo here.

Merges to releng/10.0 should now be done to the root of the branch.

For future branches during the release cycle, unless otherwise noted,
this change will be done as part of the stable/ and releng/ branch
creation.

- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Regenerate

Approved by: re (blanket)

Regenerate the configure script before running it.
Set the default config file to /var/unbound/unbound.conf.

Approved by: re (blanket)

Don't include the build date or command-line arguments in the binary.

Approved by: re (blanket)

Due to a missing command-line argument, yacc regenerated the parser but
not its header file, resulting in a mismatch between the lexer and parser
and strange errors when reading the configuration file.

Remove autoprops.

Set props and correct RCS ID tag.

Previous commit accidentally left out the umask change.

Set the correct prefix and exec-prefix.

Regenerate.

Approved by: re (blanket)

The unbound-control-setup script needs to be generated so it knows where
to place the keys. Also, the correct umask is 027, not 026, although it's
not likely to make any difference.

Move more prototypes around, and remove one that wasn't used.

Forgotten in r255579: #include fixes.

Approved by: re (blanket)

Numerous fixes to make Unbound compile cleanly:

- cast through void * to silence alignment warnings (presumably false
positives resulting from poor API design)

- constify a few function arguments

- move prototypes for callbacks into a common header

- now that the prototypes are in scope, fix instances of function
definitions that don't match the prototype or what the caller
actually passes

- hide a conditionally unused global variable behind the same #ifdef
that controls its use

Approved by: re (blanket)

Move prototypes into header.

Approved by: re (blanket)

Two helper scripts for porting Unbound:

- freebsd-configure.sh runs ./configure with the correct parameters
and regenerates the lex and yacc code.

- freebsd-sources.pl untangles the upstream Makefile and generates
source lists for our Makefiles.

Approved by: re (blanket)

Upgrade to 1.4.20.

Minimal subset of the unbound sources.
