Also make important events in init's life NOTICE rather than INFO,
and ensure that NOTICE events actually make it to the kernel log.
Also fix the logging so that if you have a printf format string
error, the compiler now catches it.
Also give messages from init, ueventd, and watchdogd distinct tags.
(Previously they'd all call themselves "init", and dmesg doesn't
include pids, so you couldn't untangle them.)
Also include the tag in SELinux messages.

This change defines atrace_* functions for the host that act as
no-ops, which makes it easier to add tracing in ART.

This was supposedly used to enable logging when !HAVE_ANDROID_OS
but it's only used in a file that's target specific.

On 64 bit systems, calls to dump_backtrace_to_file or dump_tombstone
try and directly contact the correct debuggerd (32 bit vs 64 bit)
by reading the elf information for the executable.
Unfortunately, system_server makes a call to dump_backtrace_to_file
and it doesn't have permissions to read the executable data, so it
defaults to always contacting the 64 bit debuggerd.
This CL changes the code so that all dump requests go to the 64 bit
debuggerd, which reads the elf information and redirects requests for
32 bit processes to the 32 bit debuggerd.
Testing:
- Forced the watchdog code in system_server to dump stacks and
verified that all native stacks are dumped correctly.
- Verified that dumpstate and bugreport still properly dump the native
processes on a 64 bit and 32 bit system.
- Intentionally forced the 64 bit to 32 bit redirect to write only a
byte at a time and verified there are no errors, and no dropped data.
- Used debuggerd and debuggerd64 to dump 32 bit and 64 bit processes
seemlessly.
- Used debuggerd on a 32 bit system to dump native stacks.

Under some unknown circumstances, debuggerd could become unresponsive.
If you try and take a bugreport during this time, it will hang forever.
Adding functions that have a timeout will allow dumpstate to stop if
dumping is taking too long.

Packets captured and logged by the NFLOG target are unicast, so
extend to catch and decode them. To avoid escaping issues, the raw
contents are passed around as hex strings.

This means that code that uses libcutils no longer has to ensure that
it's set ANDROID_SMP in the calling code's Android.mk for this to
function correctly.

The static libcutils tests cannot be built when using libc++ because
there are multiple symbol definition errors between libc++ and libgcc.
