9e7a370bd2 Introduce channel flags in libcasper.
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.

321aa05b3b Introduce syslog service for 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.

fff97aa66a We return a pointer when we are using cap_init() or cap_service_open()
function, so check if cap_chanel_t is NULL is not enough.
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.

82ffa91f39 Introduce caspermocks.
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.

f68ddbf508 Use hardcoded IPv4/IPv6 addresses for google-public-dns-a.google.com instead
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.

a78ff3f4f3 In libcasper, prefer to send a function index or service name over the IPC
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.
