This patch breaks up ip6_rt_copy() into ip6_rt_copy_init() and
ip6_rt_cache_alloc().
In the later patch, we need to create a percpu rt6_info copy. Hence,
refactor the common rt6_info init codes to ip6_rt_copy_init().

This patch allows user to randomize the system-priority in an ad-system.
The allowed range is 1 - 0x while default value is 0x. If user
does not specify this value, the system defaults to 0x, which is
what it was before this patch.

Currently, each dynamic netconsole_target uses its own separate mutex
to synchronize the configuration operations. This patch replaces the
per-netconsole_target mutexes with a single mutex -
dynamic_netconsole_mutex. The reduced granularity doesn't hurt
anything, the code is minutely simpler and
