da8a23277e CLI: Dumping internal data structures to files, not to debug output
All the 'dump something' CLI commands now have a new mandatory
argument -- name of the file where to dump the data. This allows
for more flexible dumping even for production deployments where
the debug output is by default off.

Also the dump commands are now restricted (they weren't before)
to assure that only the appropriate users can run these time consuming
commands.

b0e97617d9 Lib: Improve IP/net hashing
Backport some changes from branch oz-parametric-hashes. Replace naive
hash function for IPv6 addresses, fix hashing of VPNx (where upper half
of RD was ignored), fix hashing of MPLS labels (where identity was used).

64a2b7aaa3 Log message before aborting
Log message before aborting due to watchdog timeout. We have to use
async-safe write to debug log, as it is done in signal handler.

13225f1dbf Filter: Faster prefix sets
Use 16-way (4bit) branching in prefix trie instead of basic binary
branching. The change makes IPv4 prefix sets almost 3x faster, but
with more memory consumption and much more complicated algorithm.

Together with a previous filter change, it makes IPv4 prefix sets
about ~4.3x faster and slightly smaller (on my test data).

725d9af94a Lib: Add Blake2s and Blake2b hash functions
The Babel MAC authentication RFC recommends implementing Blake2s as one of
the supported algorithms. In order to achieve do this, add the blake2b and
blake2s hash functions for MAC authentication. The hashing function
implementations are the reference implementations from blake2.net.

The Blake2 algorithms allow specifying an arbitrary output size, and the
Babel MAC spec says to implement Blake2s with 128-bit output. To satisfy
this, we add two different variants of each of the algorithms, one using
the default size (256 bits for Blake2s, 512 bits for Blake2b), and one
using half the default output size.

Update to BIRD coding style done by committer.

c48ebde5ce sysdep: Add wrapper to get random bytes
Add a wrapper function in sysdep to get random bytes, and required checks
in configure.ac to select how to do it. The configure script tries, in
order, getrandom(), getentropy() and reading from /dev/urandom.

6479e403ef Filters: If somebody doesn't like _Thread_local, don't fail for now, just be a little slower.
When the parallel execution comes into place, we'll likely enforce this
C11 feature. It's much simpler and also faster than pthread_[sg]etspecific().
