Subject: [PATCH] ldns: fix the build in FreeBSD's base system

This adds an ldns/internal.h C header, containing a copy of the
function prototypes for internal functions not exposed in the API.

It effectively works around the following compilation error:
error: no previous prototype for function [-Werror,-Wmissing-prototypes]

This header is not installed, and does not affect the API exposed.

Tested on FreeBSD/amd64 (14.0-CURRENT).
