Thomas Haller 5ac481bbc0 import patches from rhel-7.4 
Let's keep rhel-7.4 and Fedora package in sync, so Fedora benefits
from bugfixes during rhel-7.4 development and RHEL benefits from
additional testing by the community.

These are all upstream patches originally cherry-picked from
nm-1-8 branch.

Subject: [PATCH 01/13] libnm: fix unterminated NUL string when parsing UDev
properties
This can result in trailing garbage (which fails UTF-8 validation
checks) or even worse, in read-out-of-bounds.

Subject: [PATCH 02/13] libnm: don't cunescape \x00 encoding in
nm_udev_utils_property_decode()
UDev never creates such invalid escape sequences. Anyway,
we cannot accept a NUL character at this point. Just take
the ill escape verbatim -- it should never happen anyway.

Subject: [PATCH 05/13] shared: add nm_utils_str_utf8safe_*() API to sanitize
UTF-8 strings
Use C-style backslash escaping to sanitize non-UTF-8 strings.
The functions are compatible with glib's g_strcompress() and
g_strescape().
The difference is only that g_strescape() escapes all non-printable,
non ASCII character as well, while nm_utils_str_utf8safe_escape()
-- depending on the flags -- preserves valid UTF-8 sequence except
backslash.
The flags allow to optionally escape ASCII control characters and
all non-ASCII (valid UTF-8) characters. But the option to preserve
valid UTF-8 (non-ASCII) characters verbatim, is what distinguishes
from g_strescape().

Subject: [PATCH 06/13] device: sanitze UTF-8 values for D-Bus
ip link add name $'d\xccf\\c' type dummy
Use nm_utils_str_utf8safe_escape() to sanitize non UTF-8 sequences
before exposing them on D-Bus. The operation can be reverted client
side via nm_utils_str_utf8safe_unescape() or simply g_strcompress().
Note that this preserves all valid UTF-8 sequences as-is, with exception
of the backslash escape character and ASCII control characters. Thus, this
is a change in behavior for strings that contain such characters.
Note that nmcli is not changed to somehow unescape the string before
printing. As the string is not valid UTF-8 (or contains ASCII characters
that need escaping), they are not printable as-is, so unescaping before
printing makes little sense.

Subject: [PATCH 10/13] libnm: add testable libnm/nm-libnm-utils.c file
Previously, internal parts of libnm were not testable.
Instead, add "libnm/nm-libnm-utils.c" and "libnm/libnm-utils.la"
to contain code that can be statically linked with a new
test "libnm/tests/test-general".

libnm-core.a should only be linked once in libnm.so. Previously,
it was linked twice, once as part of libnm-utils.a and once
directly in libnm.so.
