The code is a bit messy, as it starts with space after text and at some
point switches to space before text. But either way, printing space
before *and* after text almost certainly leads to printing more
whitespace than necessary.

This enables a user to remove an offline peer from the kernel data
structures. This could for example be useful when deliberately scaling
in peer nodes in a cloud environment.
This functionality was first merged in:
f9dec657e4 (Richard Alpe tipc: add peer remove functionality)
And later backed out (as the kernel counterpart was held up) in:
385caeb13b (Stephen Hemminger Revert "tipc: add peer remove functionality")

Prior to this patch, If one route entry's RTA_PREFSRC and RTA_GATEWAY
both were NULL, it was supposed to be restored ONLY as a local address.
But as it didn't check tb[RTA_PREFSRC] when restoring local networks,
rtattr_cmp would return a success if it was NULL, this route entry would
be restored again as a local network.
This patch is to add tb[RTA_PREFSRC] check when restoring local networks.

Currently, the `ip ila` command tries to initialize a genl context
even when we just want to see the help for the command, which doesn't
require to talk to the kernel at all.
Delay genl initialization, which can fail if the module isn't loaded,
until the point where we will actually need it.

All users of genl have the same code to open a genl socket and resolve
the family for their specific protocol. Introduce a helper to initialize
the handle, and use it in all the genl code.

Introduce a generic function (nl_add_bearer_name()) that identifies a
bearer and adds it to an existing netlink message. This reduces code
complexity and makes the code a little bit easier to maintain.

Local ip is not required to identify a UDP bearer and shouldn't be

When switching to C99 initializers, I forgot to add this one. This means
that when trying to set an estimator value, tc would complain about
spurious duplicate estimator parameter. But much worse, the random
variable content is sent to the kernel regardless of whether an
estimator was given or not.

since kernel driver has valid default values for 'cipher' and 'icvlen',
there is no need for requiring users to specify both of them when a new
link is added. Also, prompt an error message and exit with appropriate
exit status in case of unsupported cipher suite.
