c3b1a25d46 Workaround for GCC "note" about "variable tracking size limit"
GCC complains that we are using too many variables here, probably
because of the sheer number of locals used for our tinytest macros.
Eventually we should fix that (see 30968), but this commit just
makes the "note" go away by splitting the test function into two.

261ec900db Remove variable declarations from macros in test_addr_parse()
Instead, put them in the function itself.

This is an attempt to fix the gcc warning about the "variable
tracking size limit exceeded".

34bab120df Ticket 31687: fix for tor_isinf() as well
tor_isinf() was new in 0.4.0, and also needs to look at the
same rules as clamp_double_to_i64()

ded6d9fcb4 Run test_operator_cleanup on our unit tests
Coccinelle doesn't understand it when we use "==" and "!=" and so on as
arguments to macros.  To solve this, we prefer OP_EQ, OP_NE, and so
on.

This commit is automatically generated by running
./scripts/coccinelle/test_operator_cleanup over all of the source
code in src.

25ed698fb8 Add some more of our trickier macros to tor-coccinelle.h
Note that this header file behaves a bit strangely.  It is used by
coccinelle just for the purpose of knowing how to parse
difficult-to-parse stuff.  It doesn't need to produce good C -- just
grammatical C.

c6191983e9 Add a script to tell whether a file can be perfectly parsed by spatch
spatch can let us know whether a file has parsed "perfectly" or
not.  The more perfect it parses, the likelier any semantic patches
are to apply.  I've used this script to identify problem areas in
our code.

9a101c2c0f Add a script to run spatch with appropriate arguments
It's a bit tricky to remember the right incantation to get the
proper include paths and incantations for coccinelle, but without
it, coccinelle is less effective at parsing our C.

Also, remove an extraneous h.

1b3b6d9f2d Replace low-level {var_type,struct_var}_is_*() with flag inspection

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.)

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.

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.

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.
