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

Fixes bug 31475; bugfix on commit 00a9e3732e, a.k.a svn:r136.

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.

They also cause conflicts and inconsistencies when merging forward

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

Add comments explaining the module init order.

670d402621 entrynodes: Make routine descriptor expiry notice logs less alarming

have "ex" at the end of their names.

3aba13f779 buffers: use ptrdiff_t to indicate offsets.
Previously we used int in some places and off_t for others.  Neither
is correct: ptrdiff_t is right for differences between pointers.

This is technically correct, but should not matter in practice,
