Nick Mathewson 87ca9e4d2a Move confparse.[ch] into src/lib/confmgt/
This commit only does code movement, and does not clean up after
itself.  As such, it will break compilation.  I'm separating it for
ease of review.

Nick Mathewson bf8c3164b6 Add new entries to lib/confmgt ".may_include" file
confparse.[ch] will need these; checkIncludes confirms that we have
not introduced a cycle.

Nick Mathewson fe5033d3b0 Clarify documentation on config_var_is_listable()
Here we make it clear we're only looking at listable variable names,
not at whether the variables themselves are gettable.

Also, remove an extraneous h.

(This commit is not a fixup, because of rebase conflicts.)

Nick Mathewson 9b571d4729 confparse, conftypes: Replace flags with their new names.
The old names remain as #defines that cause variables to get one or
more flags.

Now every flag-testing function in confparse.c tests exactly one flag.

Nick Mathewson 1b3b6d9f2d Replace low-level {var_type,struct_var}_is_*() with flag inspection
Since the flags are now stored with compatible numbering, we can
just OR them together and see whether the flag we want is in the
result.

(Net code removal!)

Nick Mathewson 03e4183043 typed_var: Make flags into an unsigned OR of bits.
Using a bitfield here will enable us to unify the var_type_def_t flags
with the config_var_t flags.

(This commit does not yet do that unification, and does not yet
rename or refactor any flags.  It only changes booleans into bits.)

Nick Mathewson 4f6b592691 struct_var: refactor struct_var_is*() functions to delegate
Previously they checked the individual flags inside var_type_def_t;
now they call the appropriate var_type_is_*() functions.

(These functions will be removed entirely by the end of this branch.)

Nick Mathewson 8d685aee7c config: rename "contained" to "derived", and explain it better.
Don't use "derived" directly, but check its implications for listing
and copying.

Nick Mathewson 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.)

Nick Mathewson 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.

Nick Mathewson 9d60495903 Use strtod, not atof, for parsing doubles in the configuration.

Nick Mathewson 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.

Nick Mathewson 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.

Nick Mathewson 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.

Nick Mathewson 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.

Nick Mathewson 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.

These levels get out of date really easily: we'll implement a level

They also cause conflicts and inconsistencies when merging forward
level changes.

teor 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.
