We want to log pointer values to indicate the related parties of a
log message. But we should not, because plain pointer values can be
used to defeat ASLR.
Instead, we have nm_hash_obfuscate_ptr() to managle a pointer and give
a distinct (albeit not 100% unique) 64 bit integer for logging.
But for the logging messages to be meaning-full, all related parties
must use the same static-seed.
Add a macro NM_HASH_OBFUSCATE_PTR() that uses a particular seed.
... and nm_dbus_connection_call_get_name_owner().
We are going to use GDBusConnection more instead of GDBusProxy. Hence,
these two functions are the standard repertoire and used over and over.
Their arguments are complicated enough to warrant a small helper.
It will be used for "/var/lib/NetworkManager/seen-bssids" and
"/var/lib/NetworkManager/timestamps" which currently is implemented
in NMSettingConnection.
From the files under "shared/nm-utils" we build an internal library
that provides glib-based helper utilities.
Move the files of that basic library to a new subdirectory
"shared/nm-glib-aux" and rename the helper library "libnm-core-base.la"
to "libnm-glib-aux.la".
Reasons:
- the name "utils" is overused in our code-base. Everything's an
"utils". Give this thing a more distinct name.
- there were additional files under "shared/nm-utils", which are not
part of this internal library "libnm-utils-base.la". All the files
that are part of this library should be together in the same
directory, but files that are not, should not be there.
- the new name should better convey what this library is and what is isn't:
it's a set of utilities and helper functions that extend glib with
funcitonality that we commonly need.
There are still some files left under "shared/nm-utils". They have less
a unifying propose to be in their own directory, so I leave them there
for now. But at least they are separate from "shared/nm-glib-aux",
which has a very clear purpose.
