[Ian Jackson]

The following series is available for review here:
  http://www.chiark.greenend.org.uk/ucgi/~ian/git/secnet.git/
  git://git.chiark.greenend.org.uk/~ian/secnet.git
in the following rev-list:
  base.ipv6.v3..proposed.ipv6.v3

Compared to v2, this contains important bugfixes and a couple of
stylistic improvements.

    1  Makefile.in: Use -MMD, not depend.sh
    2  Provide various wrappers for memcpy (COPY_OBJ, BUF_...)
    3  Use memcpy helpers and FILLZERO
    4  subnet_to_string: Do not allocate
    5  site: transport peers: Formalise interface to transport peers
    6  site: transport peers: Notes on multi-address-family (IPv6) support
    7  comm_if: Define the meaning of ->sendmsg returning false
    8  site: transport peers: Delete or demote unsuitable peers addresses
    9  site: Make transport_record_peers cope with multiple addresses
   10  site: transport peers: Update bulk of code for multiple addresses
   11  resolver: construct comm_addr; honour multiple addresses from the re
   12  site: Permit multiple peer addresses even if peer is static
   13  site: Remove "wishful thinking" from transport address handling comm
   14  ipv6: introduce union iaddr
   15  ipv6: More buffers in iaddr_to_string
   16  autoconf: Update to autoconf 2.69
   17  ipv6: check for support in system and in adns
   18  ipv6: Support printing, comparing, etc. IPv6 addresses
   19  udp proxy: Properly zero holes in proxied address
   20  udp: Break out udp_make_socket
   21  Make list_length and string_item_to_ipaddr const-correct.
   22  Provide ARRAY_SIZE
   23  Provide text2iaddr.
   24  udp.c: Remove some (ab)use of variable name `i'
   25  udp: Support IPv6 (mostly)
   26  udp: Support IPv6 when using authbind
   27  resolver: Support IPv6 name resolution
   28  resolver: Log reason for DNS resolution failure
   29  resolver: Support IPv6 literals
   30  Python IP addresses: Provide ipaddrset.py library
   31  Python IP addresses: Use modern ipaddr.py - supports IPv6
   32  Python IP addresses: Check for and maybe delete stale ipaddr.py
   33  Python IP addresses: Remove sys.path hacking from test script
   34  test-example: Switch to testing IPv6 too
   35  resolver: Provide input name as argument to callback
   36  Provide dict_read_string_array
   37  site: Support multiple addresses
