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.

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!)

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.)

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.)

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.

Fixes bug 31615; bugfix on 0.4.0.1-alpha.

These turned out to be unnecessary, so let's not keep them around
and let them start getting complicated.

88839ab2ac Remove _ex suffix from typed_var_*_ex() functions.
Now that the variants of these functions that took config_line_t are
gone, there is no longer any reason for the remaining variants to
have "ex" at the end of their names.

This commit was made by running this perl script over all the files
in src/:

#!/usr/bin/perl -w -i -p

s{typed_var_(assign|free|encode|copy|eq|ok|kvassign|kvencode|mark_fragile)_ex}

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.
(off_t is only for offsets and sizes on the filesystem.)

b39ee42904 compat_compiler: fix documentation for STRUCT_VAR_P
Previously we had said that off_t was a reasonable type to hold the
result of offsetof().  That isn't so: ptrdiff_t is correct.

dc199f40fb smartlist_pqueue: use ptrdiff_t instead of int for offsets.
This is technically correct, but should not matter in practice,

539158f2be config: use ptrdiff_t for all field-offset members.
Previously we used int here, but it is more correct to use
ptrdiff_t.  (This never actually matters for our code in practice,
since the structure we are managing here never exceed INT_MAX in
size.)

f311d0676c backtrace: Check the return values of snprintf() and strncpy()
We can't use strlcat() or strlcpy() in torerr, because they are defined
in string/compat_string.h on some platforms, and string uses torerr.

torerr: Try harder to flush raw assert messages before process termination
Some platforms (macOS, maybe others?) can swallow the last write before an
abort. This issue is probably caused by a race condition between write
buffer cache flushing, and process termination. So we write an extra
newline, to make sure that the message always gets through.

Fixes bug 31571; bugfix on 0.3.5.1-alpha.

87a3c5b110 Fix 64-bit return issue in parse_log_domain()
If unsigned int is 32-bits long, then our old code would give a
wrong result with any log domain whose mask was >= (1<<32).
Fortunately, there are no such log domains right now: the domain
mask is only 64 bits long to accommodate some flags.

Found by coverity as CID 1452041.
