We already know that "polling" must be non-zero at this point,
because it hasn't been modified since our check on line 1960.
So we remove this check for code clarity.

With new psi monitor support in the kernel lmkd can use it to register
custom pressure levels. Add lmkd support for psi monitors when they are
provided by the kernel and use them by default. When kernel does not
support psi lmkd will fall back to vmpressure usage.
Add ability to poll memory status after the initial psi event is triggered
because kernel throttles psi memory pressure events to one per PSI tracking
window (currently set to 1sec). Current implementation polls every 200ms
for 1sec duration after the initial event is triggered.
If ro.lmk.use_psi is set to false psi logic will be disabled even when psi
is supported in kernel.

lmkd's test depends on the socket_local_client() function from
libcutils, but since liblog also exposes this symbol weakly, that is
the symbol that gets used instead of the intended libcutil's copy of
the symbol.

This is to measure an application's behavior with respect to being LMKed
(the longer an app lives before being LMKed, the better).

Excessive number of failed kill reports when lmkd can't find an eligible
process to kill or frees not enough memory pollutes logs and bugreports.
Cleanup kill reports to remove duplicate information and rate limit failed
kill attempts at 1 report per sec. The number of suppressed failed kills
will be reported in the next lmkd report.
