This reverts commit 3614a0c5d4.
The original commit was added to check if what should be impossible
cases were happening. In the years after it was added, it doesn't
appear that these cases have happened. Recent reverts removed the
commits that caused the paranoia in the first place, making these
cases even more impossible.

logger_entry has a hdr_size field meant for backwards compatibility,
however there are a few checks that expect it to be a specific size.
More problematically, it has a variable length array element, msg[0]
at the end, that would be incorrect if the header size was not kept
static.
This change fixes up those issues to facilitate future additions.

There was an email thread about this recently, and I've been asked many
times.
For instance, if this error wasn't attributed, denials a service is
hitting would be attributed to init, and that's a recipe for disaster.
Secondarily, thinking about SELinux whenever you write a new service is
good.

logd: don't send logs before the start time on the first flushTo()
Revert "logd: drop mSequence from LogBufferElement"
Revert "logd: regression in handling watermark boundary."
Revert "logd: logcat --clear respect pruneMargin"
logd: wait for timeout via CLOCK_MONOTONIC
Revert "logd: wakeup wrap timeout if realtime changes drastically"
logd: do not attempt to sort log messages by time
Logs in logd's buffer are not in time order.
If a client connects and requests logs from a given timestamp, we
start at the beginning of the buffer and find the first entry that has
happened since that timestamp and use its sequence number to flush
logs from. This ensures that we get all logs accumulated in the
buffer since that time stamp and not just the most recent.
However there may be other logs in the buffer that happened before the
timestamp and have likely been already served to the client, therefore
we do not flush those.
We only do this for the first flush, since once we have flushed all of
the logs in the buffer, if another log comes in with a timestamp
earlier than the requested timestamp, it must be out of order and not
seen yet, since it is new even to logd.
Note! This is still broken. There is a race that logs before the
timestamp may come in out of order since the last time the client
disconnected and before it reconnects. The *only* solution to this
problem is that clients need to request logs after a given sequence
number. That will be done as a separate liblog API change, while
these changes put in the ground work to make that possible.
Note 2: the security log implementation, which is one of the most
important users of this, already captures logs from seconds before the
last previous log to work around issues with timestamps. That
workaround mitigates the above issue.
Test: logs work with logcat -t

This reverts commit 5a34d6ea43.
There is a long standing bug that logd will leak memory during its
prune process if the time on the device changes significantly forwards
then backwards. This is due to using the timestamp of each log
message to determine what log messages are yet to be processed by a
reader thread.
Various attempts have been made to rectify this, but the only solution
that safely fixes this issue is to go back to using sequence numbers
on the log messages.

This test is killing critical device services, and if it runs
repeatedly or some of the critical services have already died, it'll
force the device to reboot again and potentially consider the test a
failure.
This forces the test to reboot first, so that it is in a fresh state and
we can avoid this type of flake on the device.

The next commit will use CLOCK_MONOTONIC for the timeout, so changes
to CLOCK_REALTIME will no longer be an issue.
Test: logcat output looks sane
Change-Id: I84e5b2db3c25ea6a7024557dba7fa6cc8c9237e5
Sorting does not work in all cases:
* It only sorts messages up to 5 seconds backwards in time
* CLOCK_REALTIME, which is used as the time that is sorted, can jump
drastically
* Buffers are not sorted if there is a reader holding a region lock
Removing sorting entirely will give more consistent behavior from
logd.
Test: logcat still seems sane

If the Dex file we're trying to examine is already within the unwinder's
address space, we don't need to load it from disk or copy it across
processes.
This avoids using up virtual address space to map in dex files, and
also should be a bit faster to read since it won't go out to the file.

In the post-apocalypse, it's increasingly common for people to use ssh
port forwarding to use an adb client with a remote adb server. This
results in `adb kill-server` being catastrophic, because the client has
no way of restarting the server on the other end. Android Studio in
particular has an unforunate habit of trying to manage adb's life cycle
such that starting or exiting Studio will result in a kill-server.
Add the ADB_REJECT_KILL_SERVER environment variable which ignores
kill-server, to make this scenario a bit better.
