Linux kernel 4.3 and later supports "ambient capabilities" which are the
only way to pass capabilities to containers running as a non root uid.
Previously there was no way to allow containers not running as root
capabilities in a useful way.

When sending a build context to a remote server it may be
(significantly) advantageous to compress the build context. This commit
adds support for gz compression when constructing a build context
using a command like "docker build --compress ."

The daemon is in a separate (dockerd) binary
since docker 1.12, so should no longer be
used.
This marks the command as deprecated, and
adds it to the deprecated features list.

This adds a small C binary for fighting zombies. It is mounted under
`/dev/init` and is prepended to the args specified by the user. You
enable it via a daemon flag, `dockerd --init`, as it is disable by
default for backwards compat.
You can also override the daemon option or specify this on a per
container basis with `docker run --init=true|false`.
You can test this by running a process like this as the pid 1 in a
container and see the extra zombie that appears in the container as it
is running.
```c
int main(int argc, char ** argv) {
pid_t pid = fork();
if (pid == 0) {
pid = fork();
if (pid == 0) {
exit(0);
}
sleep(3);
exit(0);
}
printf("got pid %d and exited\n", pid);
sleep(20);
}
```

New driver options:
- `splunk-gzip` - gzip compress all requests to Splunk HEC
(enabled by default)
- `splunk-gzip-level` - change compression level.
Messages are sent in batches by 1000, with frequency of 5 seconds.
Maximum buffer is 10,000 events. If HEC will not be available, Splunk
Logging Driver will keep retrying while it can hold messages in buffer.
Added unit tests for driver.
