The class_reset command used to reset services that had been set to
"disabled" in the init.rc file to a non-disabled state. Now, if the
service was originally set to "disabled", have the reset command set
it back to disabled. Otherwise, set it to the "reset" state as it
currently does.

Dump some memory at addresses for all registers that look like they
might have valid addresses. Previously this was only done for PC
and LR.
(This is expected to be disabled before ship.)

When the tombstones are uploaded to APR, they're truncated at 64KB.
This causes the log data, which is at the end, to be lost if the
process has more than about 12 threads (which many do).
This change adds the last few lines of the log right below the
report for the crashing thread, where we should be guaranteed to
keep it.
Also, clean up trailing newlines on log messages (which end up in
the tombstone), and don't print a "------- log" banner if there
aren't any messages in that log file (e.g. slog).
Also also, don't try to show_nearby_maps unless this is the crashing
thread.

This makes two changes:
(1) Display ASCII values next to the memory dumps. For example:
I DEBUG: 00008ac4 706f6f4c 20676e69 74206425 73656d69 Looping %d times
I DEBUG: 00008ad4 7453000a 6e69726f 6f742067 0a702520 ..Storing to %p.
I DEBUG: 00008ae4 65642f00 657a2f76 55006f72 6c62616e ./dev/zero.Unabl
(The hex values are still displayed as little-endian word values, while
the ASCII part is byte oriented.)
(2) Optionally display memory dumps for all registers, not just LR
and PC, for the crashing thread. This is meant for situations where
we crash dereferencing foo->bar and want to see what the memory near
"foo" looks like -- could be handy if it got stomped by MUTF-16 text
or something recognizable.
Change #2 is currently disabled, via a compile-time setting.

Testing:
The following test cases all passed and generated log entries:
# echo -n '\03foo\0bar\0' > /dev/log/main
# echo -n '\03\0bar\0' > /dev/log/main
# echo -n '\03\0a\0' > /dev/log/main
The following entries were successfully processed by
logcat but produced no log entries:
# echo -n '\03\0\0' > /dev/log/main
# echo -n '\03a\0\0' > /dev/log/main
# echo -n '\03b\0\0' > /dev/log/main
Also tested the pathological error condition:
cat /dev/urandom > /dev/log/main
which produced many "+++ LOG: malformed log entry" errors.

When parsing log entries which may have embedded \0s, it's
possible for entry->messageLen to not be the actual
length of the string in entry->message. Detect this condition.

The Android Problem Report site shows tombstones uploaded from
devices. We can see the native stack traces for every thread,
but sometimes there's a very important bit of information sitting
in the log, and without it we can't analyze the failure.
This change modifies debuggerd so that the log contents for the
crashing process are appended to the tombstone. The format matches
the output of "logcat -v threadtime". Both "system" and "main" logs
are included (but not interleaved -- we're not that fancy).
This feature is only enabled when the "ro.debuggable" system property
is set to 1 (indicating a development device).

This adds some additional output to native crashes. For example, if
something tried to access a bit of mmap(/dev/zero) memory that had
been mprotect()ed, you might see output like this:
I DEBUG : memory map around addr 4015a00c:
I DEBUG : 40159000-4015a000 /system/lib/libstdc++.so
I DEBUG : 4015a000-40162000 /dev/zero
I DEBUG : b0001000-b0009000 /system/bin/linker
The idea is to see what's in and around the fault address to make it
easier to identify bus errors due to file truncation and segmentation
faults caused by buffer over/underruns.
No output is generated for accesses below 0x1000 (which are likely
NULL pointer dereferences) or for signals that don't set si_addr.
Also, suppress the fault address for signals that don't set si_addr:
I DEBUG : signal 6 (SIGABRT), code 0 (?), fault addr --------
We still print "fault addr" followed by 8 characters for anything
that is parsing the contents. The "address" shown for signals like
SIGABRT was meaningless and possibly confusing.

If the power key was down when we booted, we would not have
gotten the down event and thus the device would not have rebooted until
the user released and pressed it again.

Add log group to ril-daemon service. rild is the best place to
know the issue on the modem in many time. It would be helpful
if rild alone can capture the snapshot of logcat buffers at
the moment of problem.
