70bd3c4369 ospfd/ospf6d/zebra: Change interface bandwidth range and auto-cost range to 100G
Prior to this change, interface bandwidth could not be defined above 10G. With
the use of higher speed interfaces, the ability to effectively define the path
links was highly impacted. Additionally, the default auto-cost reference-bandwidth
for ospf and ospfv3 was set to 100M, which relects a much earlier time.  Changed both
the range of interface bandwidth definitions and reference bandwidths to be up to
100G.  Set the default interface bandwidth (if not defined) to 10G to make the ratio
continue to cause a cost of 10 as before.  Manual testing as well as ospf-min and
ospf-smoke passed successfully.

1bba4c938b lib: Fix some poll semantics
Two Fixes:

1) When a fd has both read and write as a .events.
(POLLHUP | POLLIN | POLLOUT) and a
thread_cancel_read_write call is executed
from a protocol, the code was blindly removing
the fd from consideration at all.

2) POLLNVAL was being evaluated before POLLIN|POLLOUT
were being evaluated.  While I didn't see a case
of POLLNVAL being included with other .revent flags
I decided to move the POLLNVAL and POLLHUP handling
to the same section of code.

Additionally the function thread_cancel_read_write
was poorly named and let me to poorly implement
the poll version of it.  I've renamed the function
thread_cancel_read_or_write in an attempt to
make this problem moot in the future.

009a4a07ff lib/vty: don't clear output buffer on input EOF
A VTY's input can be closed without the output becoming unavailable.
This happens both on stdio when stdin ends, as well as over TCP when an
unidirectional input shutdown() happens.

In such a case, resetting the output buffer is not appropriate since
there might still be data to be successfully written.

27e7f29029 lib: fix "reduce strcmp in CLI" fallout (10bac801)
In "lib/cli: reduce strcmp in CLI hot paths", I failed to notice that
CMD_VARIABLE as a boolean test covers a superset of the other types of
variables.  Thus, the patch broke processing of IP/IPv6/Integer range
parameters in the CLI.

Fix by some reordering and introducing TERMINAL_RECORD macro (which
marks whether a given terminal type is a parameter) to be used in places
where the check is really for all kinds of variables.

from.  Another commit will print that information on crashes.

1f9a9fffc1 Fix most compiler warnings in default GCC build.
Fix lots of warnings. Some const and type-pun breaks strict-aliasing
warnings left but much reduced.

* bgp_advertise.h: (struct bgp_advertise_fifo) is functionally identical to
  (struct fifo), so just use that.  Makes it clearer the beginning of
  (struct bgp_advertise) is compatible with with (struct fifo), which seems
  to be enough for gcc.
  Add a BGP_ADV_FIFO_HEAD macro to contain the right cast to try shut up
  type-punning breaks strict aliasing warnings.
* bgp_packet.c: Use BGP_ADV_FIFO_HEAD.
  (bgp_route_refresh_receive) fix an interesting logic error in
  (!ok || (ret != BLAH)) where ret is only well-defined if ok.
* bgp_vty.c: Peer commands should use bgp_vty_return to set their return.
* jhash.{c,h}: Can take const on * args without adding issues & fix warnings.
* libospf.h: LSA sequence numbers use the unsigned range of values, and
  constants need to be set to unsigned, or it causes warnings in ospf6d.
* md5.h: signedness of caddr_t is implementation specific, change to an
  explicit (uint_8 *), fix sign/unsigned comparison warnings.
* vty.c: (vty_log_fixed) const on level is well-intentioned, but not going
  to fly given iov_base.
* workqueue.c: ALL_LIST_ELEMENTS_RO tests for null pointer, which is always
  true for address of static variable.  Correct but pointless warning in
  this case, but use a 2nd pointer to shut it up.
* ospf6_route.h: Add a comment about the use of (struct prefix) to stuff 2
  different 32 bit IDs into in (struct ospf6_route), and the resulting
  type-pun strict-alias breakage warnings this causes.  Need to use 2
  different fields to fix that warning?

general:

* remove unused variables, other than a few cases where they serve a
  sufficiently useful documentary purpose (e.g.  for code that needs
  fixing), or they're required dummies.  In those cases, try mark them as
  unused.
* Remove dead code that can't be reached.
* Quite a few 'no ...' forms of vty commands take arguments, but do not
  check the argument matches the command being negated.  E.g., should
  'distance X <prefix>' succeed if previously 'distance Y <prefix>' was set?
  Or should it be required that the distance match the previously configured
  distance for the prefix?
  Ultimately, probably better to be strict about this.  However, changing
  from slack to strict might expose problems in command aliases and tools.
* Fix uninitialised use of variables.
* Fix sign/unsigned comparison warnings by making signedness of types consistent.
* Mark functions as static where their use is restricted to the same compilation
  unit.
* Add required headers
* Move constants defined in headers into code.
* remove dead, unused functions that have no debug purpose.
