[dnscap-users] Release 1.11.1

[Jerry Lundström]

Hi all,

This release fixes a lot of issues found by code analysis, adds a
explicit memory zeroing function to remove account information (read
when dropping privileges) and adds code coverage reporting.

Packages are available at: <https://dev.dns-oarc.net/packages/>

The `dnscap_memzero()` will use `explicit_bzero()` on FreeBSD and
OpenBSD, or `memset_s()` (if supported), otherwise it will manually set
the memory to zero. This will hopefully ensure that the memory is zeroed
as compilers can optimize out `memset()`'s that is just before `free()`.

The plugins exit code for the help option `-?` has been changed to 0 to
have the same as `dnscap -?`.
