Improve name generation on concurrent requests

Fixes #2586

This fixes a few races where the name generator asks if a name is free
but another container takes the name before it can be reserved.  This
solves this by generating the name and setting it.  If the set fails
with a non unique error then we try again.

daemon: container: properly handle paths with symlink path components

This patch fixes the incorrect handling of paths which contain a
symlink as a path component when copying data from a container.
Essentially, this patch changes the container.Copy() method to
first "resolve" the resource by resolving all of symlinks encountered
in the path relative to the container's rootfs (using pkg/symlink).

integration-cli: cp: added symlink-related tests

This patch adds cli integration tests for #5619, which are tests
to ensure that symlinks are kept relative to the container rootfs
(even when a path component).
