9135c1f0ca Fixes bug in protocol flushing and rtable pruning.
When route was propagated to another rtable through a pipe and then the
pipe was reconfigured softly in such a way that any subsequent route
updates are filtered, then the source protocol shutdown didn't clean up
the route in the second rtable which caused stale routes and potential
crashes.

48b15ef10f Fixes stuck connection during BGP session shutdown.

then a protocol waited indefinitely to be able to
send notification packet to close the session.

ef4a50be10 Better packet priority and traffic class handling.
Implements support for IPv6 traffic class, sets higher priority for OSPF
and RIP outgoing packets by default and allows to configure ToS/DS/TClass
IP header field and the local priority of outgoing packets.

a5e9f3d26f Restructures birdc and birdcl to merge duplicated code.
The BIRD client code is restructured that most of the code (including
main function) is shared in client.c, while birdc.c and birdcl.c contain
just I/O-specific callbacks. This removes all duplicated code from
variant-specific files.

efd6d12b97 Adds two new default GCC options.
Adds two new default GCC options related to optimizations
(-fno-strict-aliasing and -fno-strict-overflow). This
should fix some hyperaggressive GCC optimizations.

Also updates autoconf option detection.

8df02847e8 Fixes a compatibility issue in OSPFv2 PtP links.
BIRD used zero netmask in hello packets on all PtP links, not just on
unnumbered ones. This patch fixes it and adds option 'ptp netmask'
for overriding the default behavior.

Thanks to Alexander V. Chernikov for the original patch.

9ff5257357 Better handling of global addresses as configured NBMA neighbors in OSPFv3.
Configured NBMA neighbors in OSPFv3 should be link-local addresses, old
behavior was to silently ignore global ones. The patch allows BIRD to
accept global ones, but adds a warning and a documentation notice.

Thanks to Wilco Baan Hofman for the bugreport.

568d9c9fae Fix birdcl async message handling
Fix handling of async messafe in the bird light client. The async message
may occure at the any moment so we need the client to liste for the
message from server when it waits for user input.

ce13485374 Fix birdcl questionmark handling
Fix handling of questionmark handling in the bird light client. The
questionmark should display help when it is the last non-blank character on
command line. Otherwise the questionmark does not have any special meaning
and it could be a part of a pattern.

8322ecde12 Add lightweight client - birdcl
Restructure client/ subdir. Add two different flavors of client.
The full featured birdc client code is in client/birdc/.
The new light client birtcl is in client/birdcl/.
Common sources of both clients are directly in client/.

Rework on-line auto-completion in client/command.c to conditionally turn off
ncurses-specific code.

Add lightweight client without libreadline and ncurses dependencies - birdcl.
The birdcl lacks support of history, on-line auto-completion and there
are different implementations of "more" functionality and help on '?' press.
New client operates in canonical terminal mode (apart from "more" display)
and therefore all commands have to be executed by a return key including help
commands (called by '?' character in the end of the line).
Apart from these limitations the interaction style should be the same as
for the full client - birdc.
Build of birdcl is always on (independent on --enable-client parameter).

e454916149 Pull out independent routines from client_full.c
Pull out routines for interacting with the server and interpreting
internal commands which are not dependent on libreadline and
ncurses libraries.

This is a preparation step for a new lightweight birdc client.

Tomas Hlavacek
5c2c4ea8b1 Rename client/client.c to client_full.c
Rename client/client.c to client-full.c and change the Makefile accordingly.
This is a preparation step for introducing a new lightweight client which
should reuse as much code as possible from the old one but it should not depend
on external libraries.
