Occasionally we see cases when 40ms polling is still too conservative.
Change to 10ms polling period. Since the polling happens only after PSI
signal and continues for 1sec this should not affect system performance.

Exit time destructors already caused trouble (see

Call android_get_control_file on last_kmsg files if the file
descriptor is provided by init.
Also, uses base::Read(File|Fd)ToString functions to read the
files (because load_file doesn't support fd arguments).
Test: charger mode
Test: manual kernel panic, then start charger; seen last kmsg.

Monitor for FUNCTIONFS_UNBIND as well, so that in the case where we get
FUNCTIONFS_BIND, FUNCTIONFS_UNBIND, FUNCTIONFS_BIND, we don't trigger an
assertion failure from seeing two FUNCTIONFS_BINDs.

* changes:
libbase: realpath is wrapped with TEMP_FAILURE_RETRY
liblp: Replace open with GetControlFileOrOpen
init: expand prop in 'file'
libcutils: android_get_control_file uses realpath.
If we fail to submit writes for some reason (e.g. the USB cable was
unplugged), another thread that's waiting on the write mutex can enter
SubmitWrites and attempt to resubmit the writes that we already failed
to submit, leading to a failed assertion of !IoBlock::pending.
Increment writes_submitted_ before actually calling io_submit, so we
skip over these writes and fall through to exit.

The definitions for event log tags are currently in system/core. Instead
of keeping them there, reserve a range for these event tags and move
them into com.android.server.policy.
Currently it is only used by PhoneWindowManager.

The function do_for_partitions() takes a const std::string
reference, so it's inefficient to pass a std::string::c_str().

When a function argument takes a std::string, it's inefficient to
pass std::string::c_str(), since that creates an additional copy.
So we change these calling sites.

This is necessary to get the correct APEX namespace setup for apps that
executes binaries from there.
In older releases no linker config applied to binaries in /data, so the
fallback config in /system/bin/linker was used, which basically just looked
up libraries in /system/{lib,lib64}. With the introduction of APEXes that
location no longer contains the complete set of libraries, so this is
necessary to retain functional parity.
Strictly speaking this fallback rule should apply as last resort for a
binary in any location, but the linker does not accept "dir.system = /".

There are a bunch of branches that check "id >= LOG_ID_MAX", but because
C++ hates you, this does a promotion to signed int despite the
fact that both sides of the comparison are the same enum with an
underlying type of unsigned int. (C++17 §7.6.3)
Return LOG_ID_MAX instead of a value that gets promoted to signed -1, to
avoid this.

Previous change If154dc364711bf7c86f32e24ddcd10be359386de called
"lmkd: Do not downgrade/ignore events when swap is full" added SwapTotal
into meminfo structure without adding the field into events.logtag file.
This results in logs which missing field and all fields starting with
"SwapFree" get reordered as a result. Fix this by adding the missing field
into events.logtag.

SetupCgroups is called by init process during early-init stage and is not
supposed to be called again by anyone else. Ensure that the caller is the
init process, make sure cgroup.rc file is written only one time, keep the
file descriptor to cgroup.rc file open by the init process to ensure all
its further mappings stay valid even if the file is deleted.
