946cedfcfe Filter: Implement soft scopes
Soft scopes are anonymous scopes that most likely do not contain any
symbol, so allocating regular scope is postponed when it is really
needed.

35f88b305a Nest: Allow specifying security keys as hex bytes as well as strings
Add support for specifying a password in hexadecimal format, The result
is the same whether a password is specified as a quoted string or a
hex-encoded byte string, this just makes it more convenient to input
high-entropy byte strings as MAC keys.

714238716e BGP: Add support for BGP hostname capability
This is an implementation of draft-walton-bgp-hostname-capability-02.
It is implemented since quite some time for FRR and in datacenter, this
gives a nice output to avoid using IP addresses.

It is disabled by default. The hostname is retrieved from uname(2) and
can be overriden with "hostname" option. The domain name is never set
nor displayed.

Minor changes by committer.

61dae32b29 Nest: Per-channel debug flags
The patch add support for per-channel debug flags, currently just
'states', 'routes', and 'filters'. Flag 'states' is used for channel
state changes, remaining two for routes passed through the channel.
The per-protocol debug flags 'routes'/'filters' still enable reporting
of routes for all channels, to keep existing behavior.

The patch causes minor changes in some log messages.

8a68316eb9 Nest: Add command to request graceful restart
When 'graceful down' command is entered, protocols are shut down
with regard to graceful restart. Namely Kernel protocol does
not remove routes and BGP protocol does not send notification,
just closes the connection.

265419a369 Custom route attributes
For local route marking purposes, local custom route attributes may be
defined. These attributes are seamlessly stripped after export filter to
every real protocol like Kernel, BGP or OSPF, they however pass through
pipes. We currently allow at most 256 custom attributes.

This should be much faster than currently used bgp communities
for marking routes.

7152e5efbb Build system reworked to one global Makefile with includes and no nesting
Also removed the lib-dir merging with sysdep. Updated #include's
accordingly.

Fixed make doc on recent Debian together with moving generated doc into
objdir.

Moved Makefile.in into root dir

Retired all.o and birdlib.a
Linking the final binaries directly from all the .o files.

f4a60a9bc4 Channels - explicit links between protocols and tables

9b9a7143c4 Conf: Fixes bug in symbol lookup during reconfiguration
Symbol lookup by cf_find_symbol() not only did the lookup but also added
new void symbols allocated from cfg_mem linpool, which gets broken when
lookups are done outside of config parsing, which may lead to crashes
during reconfiguration.

The patch separates lookup-only cf_find_symbol() and config-modifying
cf_get_symbol(), while the later is called only during parsing. Also
new_config and cfg_mem global variables are NULLed outside of parsing.
