logd: add getEventTag command and service
Will register a new event tag by name and format, and return an
event-log-tags format response with the newly allocated tag.
If format is not specified, then nothing will be recorded, but
a pre-existing named entry will be listed. If name and format are
not specified, list all dynamic entries. If name=* list all
event log tag entries.
Stickiness through logd crash will be managed with the tmpfs file
/dev/event-log-tags and through a reboot with add_tag entries in
the pmsg last logcat event log. On debug builds we retain a
/data/misc/logd/event-log-tags file that aids stickiness and that
can be picked up by the bugreport.
If we detect truncation damage to /dev/event-log-tags, or to
/data/misc/logd/event-log-tags, rebuild file with a new first line
signature incorporating the time so mmap'd readers of the file can
detect the possible change in shape and order.
Manual testing:
Make sure nc (netcat) is built for the target platform on the host:
$ m nc
Then the following can be used to issue a request on the platform:
$ echo -n 'getEventTag name=<name> format="<format>"\0EXIT\0' |
> nc -U /dev/socket/logd
Test: gTest logd-unit-test --gtest_filter=getEventTag*

logd: record multiple duplicate messages as chatty
If a series of messages arrive from a single source with identical
message content payload, then suppress them and generate a chatty
report. The checking is done on a per log id basis.
This alters the assumption that chatty messages are always at the
oldest entries, they now show up in the middle too. To address this
change in behavior we print the first line, a chatty reference
which internally takes little space, then the last line in the series.
This does not conserve processing time in logd, and certainly has no
impact on the long path of formatting and submitting log messages from
from the source, but it may contribute to memory space and signal to
noise savings under heavy spammy loads.

liblog: logd: Add android_lookupEventTag_len()
Allows us to mitigate the impact of MAP_PRIVATE and copy on write by
calling android_lookupEventTag_len instead of android_lookupEventTag,
and delaying the copy on write impact to the later. We return a
string length in a supplied location along with the string pointer
with android_lookupEventTag_len(const EventTagMap* map, size_t* len,
int tag). The string is not guaranteed to be nul terminated. Since
android_lookupEventTag() called even once can cause the memory
impact, we will mark it as deprecated, but we currently have no
timeframe for removal since this is a very old interface.
Add an API for __android_log_is_loggable_len() that accepts the non
null terminated content and fixup callers that would gain because the
length is known prior to the call either in the compiler or at
runtime. Tackle transition to android_lookupEventTag_len() and
fixup callers.
On any application that performs logging (eg: com.android.phone)

logd: correct for number of elements in prune
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.

Revert "logd: Add minimum time bucket statistics"
This forward port reverts
commit e457b74ce6ee6d799812dc2ec5e4b8b18bcd3e91
No longer as necessary once we add
liblog: Instrument logging of logd write drops
Although this provided an indication of how close statistically we
were to overloading logd it is simpler to understand fails thus to
hunt and peck a corrected value for /proc/sys/net/unix/max_dgram_qlen

logd: Add minimum time bucket statistics
* Only enabled for dev builds because halves performance.
- Used to establish if /proc/sys/net/unix/max_dgram_qlen
is appropriate for the platform
(see logd/LogStatistics.cpp comments)
- enabled if logd.dgram_qlen.statistics is not zero/empty
