Simon McVittie 0735c401a7 internals: Use negative numbers to indicate no malloc failure simulation 
If we set the countdown to simulating a failed allocation to
_DBUS_INT_MAX, then it will decrement every time we allocate memory,
eventually reaching 0 and triggering a simulated malloc failure.
In practice this does not happen during unit testing, because all of
our tests are (intentionally!) short enough that this can't happen,
but it can happen if a build of dbus with embedded tests enabled is
used for the "real" dbus-daemon or a "real" D-Bus service, either
during debugging or unintentionally, as noted on dbus/dbus!493.

We cannot simply special-case `_DBUS_INT_MAX` to never be decremented,
because _dbus_test_oom_handling() relies on the counter being
decremented even while we are not simulating malloc failure, as a way
to count the number of allocations as an upper bound for how long to
set the countdown during subsequent test runs.

Instead, reserve all negative numbers to represent the absence of
malloc failure simulation, while still being able to count allocations
by comparing two different negative numbers.
