We have already searched for the start point, the start filter check
is paranoia that removes out-of-order entries that we are undoubtably
interested in. Out-of-order entries occur under reader pressure, as
the writer gets pushed back from in-place sorted order and lands it
at the end for the reader to pick it up. If this occurred during a
batch run or a logger thread wakeup, the entry could be filtered out
and never output to the reader.
Found one case where logcat.tail_time* tests failed which was fixed
with this adjustment.

* changes:
adb: libusb: recognize devices with multiple interfaces.
adb: libusb: wait for devices to become accessible.
adb: libusb: switch to hotplug for device detection.
adb: silence noise.
While a reader is present, consider it a success, and not busy, if a
buffer is pruned down to pruneMargin plus one second of additional
margin of logspan. If not busy, no need to trigger any mitigations
regarding the readers, or to report any errors.
Side Effects are we no longer mitigate the reader when performing
chatty filtration. This is a positive side effect because we were
getting --wrap wakeups that seemed premature.
Add kickMe() and isBusy() methods to ease maintenance and uniformity
of actions.
Test: gTest liblog-unit-tests, logd-unit-tests & logcat-unit-tests
Test: manual: 'logcat -b all -c' repeat in a loop, at various logging
load levels, simultaneously 'logcat -b' all in another session.

AVB is going to support different modes to handle dm-verity errors.
See the following CL for more details:
- https://android-review.googlesource.com/#/c/392873/
The verity mode is controlled by bootloader through androidboot.veritymode in
kernel command line. fs_mgr should read the value from there and specify the
corresponding flag when loading dm-verity table into kernel.
Also removes some unused #include libraries.
Bug: 38157502
Test: Manually tested different dm verity modes:
- "restart_on_corruption" (androidboot.veritymode=enforcing)
- "ignore_corruption" (androidboot.veritymode=logging)
- None, default mode is EIO in kernel (androidboot.veritymode=eio)

A bug was introduced by commit 8bf37d7a wherein we accidentally only
look at the first interface of a device when checking whether a USB
device was an ADB device or not.

Android's host linux libusb uses netlink instead of udev for device
hotplug notification, which means we can get hotplug notifications
before udev has updated ownership/perms on the device.
When detecting a new device, poll the device file for a while until we
can access it, before trying to open it.

Test: manually incrased timeout and chmodded a device betwen 0 and 664
Change-Id: I3c714f630940df02b407442592301e2bbb3d9653
Switch from polling in a loop to using libusb's hotplug API to detect
when devices arrive and leave. Use this to remove devices that were
inaccessible when they're unplugged.

- android::pidToUid() additional checking. Make sure if we have to
convert a PID to an UID that the parse of /proc/<pid>/status
requires a trailing space after the number
- android::tidToPid() added, in the same vein as android::pidToUid().
- stats.tidToPid() added
- If no credentials, set PID to 0 and UID to DEFAULT_OVERFLOWUID
- If credentialed PID is 0, use stats.tidToPid()
- If credentialed UID is DEFAULT_OVERFLOWUID, use stats.pidToUid()
Test: remove +passcred from logd.rc for daemon and confirm very few
UID=65534 or PID=0 cases actually show up

Inject a message for event_tag_filter and bucket tests. The former
registered an occasional failure.
Switch order of EXPECT checks so that constant is on the right so
that error reports make more sense.

The default constructor of FileMap was missing an initializer for the
mFileMapping variables. This results in CloseHandle being called with
a "random" value, which can cause havoc in Win32 process over time (e.g.
in the case of libaapt2_jni.dll, which is loaded in a JVM process).
Also, update the code to use "NULL" for invalid file map handle
and "INVALID_HANDLE_VALUE" for invalid file handle.

logd.sepolicy_rate_limiter_* tests can fail individually so join them
together into one test. The new test logd.sepolicy_rate_limiter
fails as a group if the background sepolicy activity is too high, so
check it and report a warning that the test can fail as a result so it
can be forgiven during unit testing. The failure remains as a VTS
performance threshold that requires investigation.
The test takes a total of 45 seconds to run, it was split up as this
approaches the 60 second test timeout on go/apct.
Test: gTest logd-unit-tests --gtest_filter=logd.sepolicy_rate_limiter
(run in loop ensuring passes do not interfere with eachother)

adb: move all cleanup to a function with defined ordering.
adb: make `adb kill-server` wait for the server to die.
adb: libusb: replace sleep with timed CV wait.
The linker no longer enables greylist by default, it
needs to be explicitly enabled by specifying corresponding
flag.
