Add support for building "modular" tests, which require GLib and dbus-glib

For the moment, the CMake build system only knows about the existing
"embedded tests"; make it define both symbols, though.

We use GLib because it has GTester (and life's too short to write yet another

fd.o #31515 for thoughts on incorporating just those two functions in a
separate library in the dbus tarball).

I'm not using DBusLoop for the main loop because I specifically don't
want to use non-public API or ABI of libdbus in the modular tests. If we make

Doing a malloc and a hex-encoding pass just to produce a _dbus_verbose
message (i.e. a message that, in practice, nobody will see) seems like
overkill, and this block had incorrect error handling (not checking the
result of _dbus_string_init) which upsets static analysis tools.

dbus-launch: pass_info: always free strings on OOM

This doesn't really do anything, because we're about to exit anyway, but
it placates static analysis tools.

dbus_connection_dispatch: remove dead code

There's no way pending can be non-NULL here; if it was, we'd have jumped
straight past this block (getting filters from the connection), because
replies to pending calls don't go through filters.

Spelling fix.

Definition is obsolate with commit e0fc90bdf2c60a4c77fffaf490d6f06b2bd6999d

To avoid double dbus version definitions take values from configure.ac.

DBusNonceFile: don't always fail when use_subdir=TRUE, i.e. on Unix

In shell-like pseudocode, the desired result is:

if $use_subdir
  dir = $tmpdir/dbus_nonce-$random
  path = $dir/nonce
  mkdir $dir
  write file at $path
else
  dir = $user_owned_place
  path = $dir/dbus_nonce-$random
  write file at $path

However, /nonce was accidentally appended to $dir instead of $path,
resulting in an attempt to mkdir /tmp/dbus_nonce-XXXX/nonce when
dbus_nonce-XXXX hadn't been created yet.
