Also:
- replace all /* fallthrough */ comments with portable fallthrough;
pseudo keyword to accomodate both gcc and clang
- add missing break; statements as required by older versions of gcc
- cleanup some code to remove unnecessary fallthrough

Instead of scaling the bandwith to something between 1 and 100, just
send down the bandwidth Available for the link.

The weight scale value might be useful to have it
change it's behavior at a later time or controlled
by something depending on how FRR is compiled/ran.
Let's start that process

Currently underlying asics get into a bit of trouble when the
nexthop weight passed down varies wildly between the different
numbers. Let's normalize the weight values between 1 and 255

Separate commit for clang-format cleanup of string
messages because I felt it would hide the actual
changes being made to the system.

- Addressed memory leak by removing `&c->peer_notifier` from the notifier list on termination. Retaining it caused the notifier list to stay active, preventing the deletion of `c->cur.peer`
thereby causing a memory leak.
- Reordered termination steps to call `vrf_terminate` before `nhrp_vc_terminate`, preventing a heap-use-after-free issue when `nhrp_vc_notify_del` is invoked in `nhrp_peer_check_delete`.
- Added an if statement to avoid passing NULL as hash to `hash_release`, which leads to a SIGSEGV.
