30f991f251 liblog: use log/log.h when utilizing ALOG macros
Test: compile

cfd5b080af system/core: preparation to pull back interfaces from android/log.h
Point to log/log.h where necessary, define LOG_TAG where necessary.
Accept that private/android_logger.h is suitable replacement for
log/logger.h and android/log.h.

Correct liblog/README

Effectively a cleanup and controlled select revert of
'system/core: drop or replace log/logger.h' and
'system/core: Replace log/log.h with android/log.h'.

Test: compile

ff2dcd9af9 system/core Replace log/log.h with android/log.h
Should use android/log.h instead of log/log.h as a good example
to all others.  Adjust header order to comply with Android Coding
standards.

3dcfa3fb1c Most accept/accept4 calls in system/core don't actually want the remote address.
So don't write the extra code for it or waste the kernel's time
copying it around.

9010a2398e lmkd: subscribe to low mempressure events.
This will make sure we get invoked in time,
and combined with a kernel change to increase
the window size (and thus rate-limit the
notifications) based on the amount of memory
on the device, this should provide a nice
balance between receiving too many notifications
vs getting notified too late.

f8857cc24a lmkd: kill a process if zoneinfo can't be read
Opening /proc/zoneinfo may return -ENOMEM under memory pressure,
assume something needs to be killed if that happens.

1a0d9be53e lmkd: make lmkd SCHED_FIFO
If kswapd runs more than lmkd it may throw away all page cache pages
before lmkd gets a chance to kill a process.  Make lmkd SCHED_FIFO
so it can react quickly to kernel low memory notifications.

b28ff91313 lmkd: mlock all memory
Use mlockall(MCL_FUTURE) to lock all lmkd pages in memory.  This
avoids lmkd thrashing when the system is low on memory.

As a side effect, it will also keep the .text sections of liblog, libm,
libc, and libprocessgroup in memory at all times.
