Major rototill in preparation for merging to 8. This is a checkpoint commit that
has only been compile tested on AMD64 so far. Summary of changes as follows:

- Split cc.h into cc.h and cc_module.h, to separate out KPI module plumbing
  (cc_module.h) from generic CC related code (cc.h). Only CC modules
  should include cc_module.h.

- Implement new DECLARE_CC_MODULE() macro, modelled on similar MAC/VFS code,
  to hide most of the machinery of creating a CC kernel module. A CC module
  author can now simply put "DECLARE_CC_MODULE(<name>, &<name>_cc_algo);"
  (replacing <name> as appropriate) at the bottom of their algo's .c file and
  have the framework handle most of the heavy lifting.

- Add new mod_init/mod_destroy function ptrs to struct cc_algo. This provides
  standardised hook functions for the framework to init/cleanup global CC module
  state on kldload/kldunload.

- Rename init/deinit function ptrs to conn_init/conn_destroy for consistency
  with the above change and to distinguish per connection init/cleanup from
  global module init/cleanup.

- Remove the global "cc_algorithm" string which was used to hold the name of the
  systemm default CC algorithm. Since switching to having the default algorithm
  always be at the head of the cc_list TAILQ, use of this string is redundant.

- Catch up with vimage changes that require inclusion of <sys/vimage.h> in
  addition to <netinet/vinet.h>.

- Simplify logic in the sysctl handlers.

- Lots of minor cleanup work.

- Update existing CC modules as required to work with new world order.
