Chatty logs would distort the average log size by elevating the
elements, but not the size. Add statistical collection for the
number of elements that report chatty, and subtract that from
the number of elements to improve the pruning estimate. Pick
minElements as 1% rather than 10% of the total with this more
accurate number of elements, to a minumum of 4.

is via /proc/sysrq-trigger

other activities in the logger.

It's less than a second, but one problem is that the cost of the current
dumping is proportional to the number of init.rc files, so the more
cleanly you factor things, the more it would cost.

* changes:
logd: clearAll by UID speedup
logd: clear return and deal with busy if readers locked
logd: update region lock after entry has passed to reader socket
logcat: do not exit buffer loop on error
logd: clientHasLogCredentials false negatives
In order to read the /proc/<pid> files from non-root users without
using CAP_SYS_PTRACE and CAP_DAC_OVERRIDE, use setresuid(..) and
setresgid(..) to switch to the process's user to copy off necessary
files for generating the breakpad minidump.

procrank only exists on userdebug/eng builds. For those builds,
procrank can be executed by running "su 0 procrank" instead of
relying on the binary being setuid root. This reduces the number
of setuid binaries on Android and allows for the deletion of
SELinux policy to support this.

- If doing a clear, skip accounting
- Ensure for busy checking, behind a region lock for instance, only
break out if there was something to do. Basically move the filter
actions first, and defer checking the region lock to the ends of
the loops.

- Propagate to caller the clearing errors, busy blocked by reader.
- For clear, perform retries within logd with a one second lul each,
telling readers to skip, but on final retry to kill all readers if
problem still persists due to block reader (or high volume logspammer).

- The reader region level indicates the location to protect, but once
it has been passed to the calling reader, then allow us to go
one beyond so that a clear or prune thread can remove the entry.

report and exit for the last error reported.

Vote three times in /proc/pid/status to look for AID_LOG group
If not, we may default to the callers UID, and the net result is
to perform the task related to that UID. For adb logcat and
shell logcat, the UID is AID_SHELL which typically has no logs,
leaving no net action taken.

If -d/-e fail, get-serialno and friends will now report an error
and return a failure status code on exit.
Also fix the behavior of -d/-e with $ANDROID_SERIAL --- -d/-e
should override $ANDROID_SERIAL, not the other way round.
I'm deleting my own comment here about always returning "unknown"
for scripts. I can't find any evidence that there are scripts
relying on that, so I think my comment meant "I fear that there
are scripts doing so".
