Naming is important, because the name of a thing should give you a good
idea what it does. Also, to find a thing, it needs a good name in the
first place. But naming is also hard.
Historically, some strv helper API was named as nm_utils_strv_*(),
and some API had a leading underscore (as it is internal API).
This was all inconsistent. Do some renaming and try to unify things.
We get rid of the leading underscore if this is just a regular
(internal) helper. But not for example from _nm_strv_find_first(),
because that is the implementation of nm_strv_find_first().
- _nm_utils_strv_cleanup() -> nm_strv_cleanup()
- _nm_utils_strv_cleanup_const() -> nm_strv_cleanup_const()
- _nm_utils_strv_cmp_n() -> _nm_strv_cmp_n()
- _nm_utils_strv_dup() -> _nm_strv_dup()
- _nm_utils_strv_dup_packed() -> _nm_strv_dup_packed()
- _nm_utils_strv_find_first() -> _nm_strv_find_first()
- _nm_utils_strv_sort() -> _nm_strv_sort()
- _nm_utils_strv_to_ptrarray() -> nm_strv_to_ptrarray()
- _nm_utils_strv_to_slist() -> nm_strv_to_gslist()
- nm_utils_strv_cmp_n() -> nm_strv_cmp_n()
- nm_utils_strv_dup() -> nm_strv_dup()
- nm_utils_strv_dup_packed() -> nm_strv_dup_packed()
- nm_utils_strv_dup_shallow_maybe_a() -> nm_strv_dup_shallow_maybe_a()
- nm_utils_strv_equal() -> nm_strv_equal()
- nm_utils_strv_find_binary_search() -> nm_strv_find_binary_search()
- nm_utils_strv_find_first() -> nm_strv_find_first()
- nm_utils_strv_make_deep_copied() -> nm_strv_make_deep_copied()
- nm_utils_strv_make_deep_copied_n() -> nm_strv_make_deep_copied_n()
- nm_utils_strv_make_deep_copied_nonnull() -> nm_strv_make_deep_copied_nonnull()
- nm_utils_strv_sort() -> nm_strv_sort()
Note that no names are swapped and none of the new names existed
previously. That means, all the new names are really new, which
simplifies to find errors due to this larger refactoring. E.g. if
you backport a patch from after this change to an old branch, you'll
get a compiler error and notice that something is missing.
The warning is wrong, because we already assert for the string length a few
lines earlier.

(cherry picked from commit c87433ebd2)
Introducing ethtool PAUSE support with:
* ethtool.pause-autoneg on/off
* ethtool.pause-rx on/off
* ethtool.pause-tx on/off
Limitations:
* When `ethtool.pause-autoneg` is set to true, the `ethtool.pause-rx`
and `ethtool.pause-tx` will be ignored. We don't have warning for
this yet.
Unit test case included.

- consistently check for success/failure of _ethtool_call_handle()
with "< 0" / ">= 0".
- drop unnecessary memset(). In the past, I argued to add this because
there were obscure cases with valgrind where this made a difference.
As it's not clear when/how that is necessary, drop it again.
Also, we want to prefer explicit struct initialization over memset(),
so if memset() would be necessary, those places would be problematic
as well.
- inline unnecessary helper functions. They had only one caller and
only make the code more verbose.
- use _ethtool_call_once() instead of _ethtool_call_handle() at places
where we use the handle only once. The handle and _ethtool_call_handle()
are useful to cache and reuse the file descriptor and the interface
name. If we only make one call with the handle, we can use
_ethtool_call_once() instead.
