Instead of passing flags (which describe a type of nvlist)
every send/recv we remember them in channel.
It's enough for use to extract them only during unwrap.
This simplify use of Casper.

syslog in libc secretly reconnects to the daemon.
Another issue is that we don't have any information from openlog(3) if we
succeeded to open log or not so we don't know if we are ready
to enter cabability mode.
Because all of that we decided we need a syslog service for Caspser.

Casper with a normal libc will still fail in capability mote so let's not
enter capability mode without casper support when we need to resolve DNS.

The idea behinds mocks is that we don't need to ifdef a lot of code in
tools itself but those defines are hidden in the casper library.
Right now the mocks are implemented as define/inlines functions.
There was a very long discussion how this should be implemented.
This approach has some advantages like we don't need to link to any additional
libraries. Unfortunately there are also some disadvantages for example it is
easy to get library out of sync between two versions of functions or that we
need extra define to compile program with casper support.
This isn't an ideal solution but it's good enough for now and should simplify
capsicumizing programs. This also doesn't close us any other ways to do those
mocks and this should evolve in time.

Non-tests/... changes:
- Add HAS_TESTS= to Makefiles with libraries and programs to enable iteration
and propagate the appropriate environment down to *.test.mk.
tests/... changes:
- Add appropriate support Makefile.inc's to set HAS_TESTS in a minimal manner,
since tests/... is a special subdirectory tree compared to the others.

of freefall.freebsd.org to unbreak the DNS tests
The address allocations for freefall.freebsd.org have changed in the past 4 years.
Use a more stable set of hardcoded addresses for now to make the tests succeed
reliably.
The hostname should be resolved dynamically instead of hardcoding the addresses in
the future. This is just a bandaid.

Some of the testcases try to manipulate sysctls that require root privileges,
e.g., "kern.sync_on_panic". Make root-privileges a hard requirement so the
tests don't raise false positives due to privilege issues when calling
sysctlbyname(3) on writable sysctls.

channel to a zygote process, rather than sending a function pointer or
service pointer. This avoids transfering pointers between address spaces,
which while robust in this case (due to the zygote being forked() from the
parent) is not generally a good idea, especially in the presence of
increasingly popular control-flow integrity and pointer protection
mitigation schemes. With this change, ping(8) and other sandboxed tools
using libcasper for DNS resolution now work on architectures with tagged
memory again.
