We were just telling GCC not to treat them as errors: this suppresses them
entirely unless at -O3. People keep trying to "fix" them, when in fact
they're false positives, as revealed with "./configure COPTFLAGS=-O3".
Fixes: #2856

I noticed that DEVELOPER was being reset to 0 by ./configure --reconfigure;
that's because we set the defaults first, then --reconfigure would only
override *unset* vars. We now set up defaults last.
We unify all our "find the default" functions, to neaten them; in
particular find_pytest and our open-coded valgrind testing function.
We can figure out whether valgrind works using /bin/true instead of waiting
until configurator is built.
We're also more careful with ${FOO-default} vs ${FOO:-default}; the former
does not replace if FOO is set to the empty string, which is possible for
some of our settings (COPTFLAGS, CDEBUGFLAGS in particular).

Drive-by fix of CONFIGURATOR_CC setting when CC is overridden on cmdline
(not via env var).
Note that clang defines __GNUC__ (to 4) :(

`./configure CC=newcc --reconfigure` didn't set CC, because reconfigure
simply replaced all values: only make it replace undefined values.
Also, it didn't change COPTFLAGS or CWARNFLAGS, even if they were previously
the defaults (eg. --reconfigure --enable-developer).

Unfortuntely we get spurious uninitialized variable warnings with
anything but -O3 or no optimization, so set default CWARNFLAGS
appropriately.

* remove libbase58, use base58 from libwally
This removes libbase58 and uses libwally instead.
It allocates and then frees some memory, we may want to
add a function in wally that doesn't or override
wally_operations to use tal.

The v1.0.9 release of libsodium added
crypto_aead_chacha20poly1305_ietf_NPUBBYTES which we use; before that it was
...IETF_NPUBBYTES.
Since that release was in April 2016, it seems fair to simply check for
ancient versions and use the internal one if found. The alternative would be
to use the older names (which are still in the header), but given we've never
tested with such old versions, this seems safer.

== is bash-only; for other shells this gives an error (meaning that you won't
get the sanity check):

If you use use CC='gcc <options>' this blocks ASAN. Of course, no
check is perfect, but this catches the obvious misuse still.

Also one less headache for reproducible builds. But unlike

Installing pytest through pip3 (at least sometimes) doesn't create a script.
This means calling `which` won't work.
Changed configure so that it can also test if the module is present by calling python/python3.
Change the error message for when pytest can't be found, so that it's clear to the user `configure` must be ran again after installing pytest.
Addresses #486 and takes into account @rustyrussell 's
comment about PYTEST defined in the environment which
always overrides without checking the version.
You can use environment variables or the commandline to set defaults.
It looks very autoconf, but you don't need to learn m4.
Doesn't cover all the obscure flags, but it's easy to extend.
