Add built-in seeds for .onion

This makes it possible for a node with `-onlynet=tor` to bootstrap
itself.

It also adds the base infrastructure for adding IPv6 seed nodes.

Also represent IPv4 fixed seed addresses in 16-byte format.

+Script to generate list of seed nodes for chainparams.cpp.
+
+This script expects two text files in the directory that is passed as an
+argument:
+
+    nodes_main.txt
+    nodes_test.txt
+
+These files must consist of lines in the format 
+
+    <ip>
+    <ip>:<port>
+    [<ipv6>]
+    [<ipv6>]:<port>
+    <onion>.onion
+    0xDDBBCCAA (IPv4 little-endian old pnSeeds format)
+
+The output will be two data structures with the peers in binary format:
+
+   static SeedSpec6 pnSeed6_main[]={
+   ...
+   }
+   static SeedSpec6 pnSeed6_test[]={
+   ...
+   }
+
+These should be pasted into `src/chainparamsseeds.h`.
