Declare version 1.7.0

This changelog: Remove obsolete Emacs local variables section

README: Ask for bugs to go to Debian (autogen)

README: Ask for bugs to go to Debian

This is where I actually look in practice.

Upstreamk changelog: Document test harness changes

regress/hplayback: Try to suppress a warning

I don't know why casting to void isn't enough to shut gcc up.

regress/hplayback: Break out Pfgets

This is more DRY and allows us to try to suppress an unused return
value warning.

Document random query ids in INSTALL and changelog

Report to stderr if we can't use getentropy

Use getentropy() for query ids if possible

Break out code for selecting query ids

Mock getentropy (with ENOSYS)

autoconf: Test for getentropy

Upstreamk changelog: start 1.6.3

Update version to 1.6.2 and document changes

Update signing keyid in release checklist

Rerun autogen.sh (updating configure script etc.)

Replace (out-of-date) copyright dates with references

README: Regenerate from HTML

README: Remove copyright dates from HTML

This is a pain to maintain and not of very much practical legal use
IMO.

INSTALL: Add today's year to the copyright notice

INSTALL: Remove email address from copyright notice

This seems otiose and undesriable.

README: comment out the reference to ftp.gnu.org

In practice I don't seem to have been able to (re)-obtain credentials
for uploading there.

Remove a pointless test of an array for NULL

Fixes this harmless warning:

  ../src/types.c:459:7: warning: the comparison will always evaluate as 'true' for the address of 'sortlist' will never be NULL [-Waddress]

Disable debugging output to stderr from adns_addr2text and adns_text2addr.

Fix typo in changelog entry for 1.6.1

Set version to 1.6.1 and document changes

INSTALL: Add missing credit and copyright year

Shorten all per-file copyright notices

We don't want to be updating all these for contributors, copyright
years, etc!

build system: Support DESTDIR

Ignore resolv.conf option `trust-ad`

I went through the resolv.conf(5) manpage and nothing else needs to be
ignored.  But, also, `trust-ad` wasn't listed?

Fixes Debian #1028112

README (from README.html): Fix all URLs to use https

README.html: Fix all URLs to use https

adns_str* etc.: Permit calling on adns_s_* values (not _max_)

This is useful because otherwise an application may not use these
values for its own errors, if that might result in them being passed
to the adns_strerror etc.

No code change: the table already has all the values.

Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>

adns_str* etc.: Return NULL rather than crashing, and docs

Previously, calling these functions with arbitrary values would cause
them to do a struct member lookup on a null pointer.  Now they return
the pointer instead.

Also, some users have been confused by the docs, and have passsed, for
example, adns_s_max_misconfig.  This is also not permitted.  Clarify
that only values actually returned by adns are allowed.

If no syscalls were made, Tensuresetup won't have been called.

(We don't want to call it because it's what handles the first
