I think this makes it much easier to figure out what information sources
were used to generate the names, and why certain names were not generated.

The meson default for static_library() are:
build_by_default=true, install=false. We never interact with the
static libraries, and we only care about them as a stepping-stone towards
the installable executables or libraries. Thus let's only build them if
they are a dependency of something else we are building.
While at it, let's drop install:false, since this appears to be the default.
This change would have fixed the issue with lib_import_common failing
to build too: we wouldn't attempt to build it.
In practice this changes very little, because we generally only declare static
libraries where there's something in the default target that will make use of
them. But it seems to be a better pattern to set build_by_default to false.
The variable is not useful outside of the loop (it'll always be null
after the loop is finished), so we can declare it inline in the loop.
This saves one variable declaration and reduces the chances that somebody
tries to use the variable outside of the loop.
For consistency, 'de' is used everywhere for the var name.
On btrfs, trying to disable FS_NOCOW_FL on a file that has data
already written will fail silently without reporting an error. To
catch such cases, let's query the flags again if the IOC_SETFLAGS
ioctl() succeeds to make sure the flags we tried to configure we're
actually accepted by the kernel.
When parse_ip_port() is directly used in a conf parser, then that's
fine, as the rvalue is already truncated.
When parse_ip_port() is used when e.g. parsing IP address with port,
then we should really refuse white space after colon.
This allows resolved and importd to be built without libgcrypt.
Note that we now say either 'cryptographic library' or 'cryptolib'.

The macro variants can be used in static initializers.
The same guard against calling __builtin_clz(0) is added as for
__builtin_clzll(0), since that's undefined behaviour too. Our code
wouldn't call it, but this avoids a potential pitfall with the macro.
All variants map 0→0. Otherwise we'd often have to handle 0 specially
in callers.
__builtin_clz takes unsigned as the argument, so there's no LOG2I macro.
I think the function name is confusing: we generally say "free_free" when
both keys and values are freed in a hash map, but here the type is an
array of strvs, so the name should be something like strv_array_free.
The function is unused since 143fadf369 (2018),
let's just drop it.
IOPRIO_CLASS_NONE with any priority value actually is an alias for
IOPRIO_CLASS_BE with priority value 4 – which is the default ioprio for
all processes.
We got this right at one place, but wrong at three others (where we
assumed the default value was 0, not 4). Let's add a
macro that encodes this properly, and use it everywhere.
One of the niceties of recurse_dir()/recurse_dir_at() is that the path
argument is decoration, it's not used for actually accessing the fs in
anyway. That's very handy in environments where chroots and relative
paths are used, as we can path in any path we like and the recursion
function will suffix with whatever it discovers but will not try to make
sense of the prefix you pass.
This works great, except that the recurse_dir_at() wrapper broke that:
it adjusted the path if NULL to "." simply for the sake of making
openat() on the top work. Let's make this adjustment more local and do
it only for the openat() itself, and otherwise pass the path through the
way we got it. This means: if a caller really wants the paths that are
concatenated to start with a "." it can just pass that. This way the
caller gets full control back of the path prefix. Win!
Note that all current users of recurse_dir_at() don't pass NULL as
second arg, hence this check is without any real effect for now. It's
preparation for future uses however.
Use product_version instead of product_name in DMI table and the string
"Hyper-V" to avoid misdetection.
