668e3a7709 config: Introduce the concept of an "ungettable" variable.
We had though to make all obsolete and invisible variables
ungettable, so that GETCONF would reject them.  But it turns out
that this isn't the current behavior of GETCONF with those
variables.  So for now, I'm leaving the current behavior unchanged.
(See ticket 31647 for a proposal to change the behavior.)

0891a31ad3 madvise: tolerate EINVAL and ENOSYS when minherit fails
These errors can occur if we are built on a system with support for
madvise(MADV_NOFORK) but then we are run on a system whose kernel
does not support that flag.

If the error is something that we don't tolerate at all, we now log
it before crashing.

Fixes bug 31696.  I am calling this a bugfix on 0.4.1.1-alpha, where
we actually started using the map_anon code.

This is similar to, but not the same as, the fix for #31570.

9d60495903 Use strtod, not atof, for parsing doubles in the configuration.
This lets us detect erroneous doubles, which previously we could not
do.

97f7efa9e3 pf: when extracting an IPv6 address, make sure we got an IPv6 address
Our code assumes that when we're configured to get IPv6 addresses
out of a TRANS_PF transparent proxy connection, we actually will.
But we didn't check that, and so FreeBSD started warning us about a
potential NULL pointer dereference.

Fixes part of bug 31687; bugfix on 0.2.3.4-alpha when this code was
added.

51475aee57 fp.c: Suppress float-conversion warnings on FreeBSD.
We used to do this on Windows only, but it appears to affect
multiple platforms when building with certain versions of GCC, and a
common pattern for defining the floating-point classifier functions.

Fixes part of 31687. I'm calling this a bugfux on 31687, when we
started suppressing these warnings on Windows.

e7d7e04155 Do not look inside bogus microdesc when listing its digest as invalid
We have code in microdescs_parse_from_string() to record the digests
of microdescriptors that we could not parse.  But right now, that
code looks at the md->digest field, which is a bit inelegant, and
will stand in the way of sensible refactoring.

Instead, use a local variable to hold the digest.

7282213bd3 Extract saved_location_to_string() from microdesc parsing.
We may be able to use this function in other places in the future;
if so, we should move it to somewhere more useful.

d8ef6b1548 Add a unit test for ed25519 identity parsing in microdescriptors
This test makes sure that we parse ed25519 identities to get the
correct data from them.  It also tests:

   * That a microdescriptor may not have two ed25519 identities.
   * That a microdescriptor may not have an ed25519 identity that is
     not a valid base64-encoded ed25519 key.
   * That a microdescriptor may have an unrecognized identity type.

It will help test the refactoring of ticket31675.

612b0a4139 subsys: Make the subsystem init order match the module dependencies
Fix levels for subsystems that depend on log/err
* winprocess (security) doesn't use err:
  * call windows process security APIs as early as possible
  * init err after winprocess
  * move wallclock so it's still after err
* network and time depend on log:
  * make sure that network and time can use logging.
  * init network and time after log
