atrace: setup saved_cmdlines_size and write only if available
Older kernels (bullhead etc) don't have saved_cmdlines_size, check and
write only if available. Also make work on non-root by setting
permissions in rc file (thanks John Reck for suggestion).

Do not set the trace clock in atrace.rc.
This reverts only the atrace.rc change from commit ea826794184be368f65f099ceac4fc31234700f6.
"Set the atrace clock to the best available value: boot, mono, or global."
This change caused a 100+ms regression in boot time. We also confirm that
the clock is set to the correct value when we call atrace, so we will
still see correct behavior after reverting this change.
Bug: 38504158
Test: Manually tested that the trace clock is updated when atrace is
called.

Set the atrace clock to the best available value: boot, mono, or global.
This reverts commit dc34097448a76a4bb09636f25567113d7a6551dc.
"Revert "Set the atrace clock to boot when possible and mono otherwise.""
...and includes a fix for devices that break with that change. Write will
fail with an Invalid Argument exception if we programmatically write a
value to the trace_file that doesn't exist in the file. So, we'll check
for both potential values we might set. If neither of them exist, fall
back to setting to 'global', which should be safe since we were doing it
before without checking.
Bug: 32379831
Test: cts-tradefed run singleCommand cts-dev --module
CtsAtraceHostTestCases passed.
Test: Manually examining trace_clock before and after running atrace shows that the
trace_clock changes as expected (for this test I disabled atrace.rc and added an
additional debug print statement):
$ cat /d/tracing/trace_clock
[local] global counter uptime perf mono boot
$ atrace --async_start freq
capturing trace...marlin:/ $ cat /d/tracing/trace_clock
local global counter uptime perf mono [boot]
$ atrace --async_stop > /dev/null
$ cat /d/tracing/trace_clock
local global counter uptime perf mono [boot]
$ atrace --async_start freq
clock is already correct!
$ atrace --async_stop > /dev/null

Set the atrace clock to boot when possible and mono otherwise.
Bug: 32379831
Test: Inspected the trace_clock while running atrace, without including the .rc file change:
$ adb shell
marlin:/ # cat /d/tracing/trace_clock
[local] global counter uptime perf mono boot
marlin:/ # atrace --async_start freq
capturing trace...
marlin:/ # cat /d/tracing/trace_clock
local global counter uptime perf mono [boot]
marlin:/ # atrace --async_stop > /dev/null
marlin:/ # cat /d/tracing/trace_clock
local global counter uptime perf mono [boot]
marlin:/ # exit
Test: Inspected the trace_clock while running atrace, after the .rc file change:
$ adb shell
marlin:/ # cat /d/tracing/trace_clock
local global counter uptime perf mono [boot]
marlin:/ # atrace --async_start freq
capturing trace...
marlin:/ # cat /d/tracing/trace_clock
local global counter uptime perf mono [boot]

Update atrace to work with tracefs, not debugfs
When tracefs is mounted, tracing is under /sys/kernel/tracing not
/sys/kernel/debug/tracing. Modify atrace to detect this situation and
get the right files.
Bug: 31856701
Test: Run atrace, check output is same where ever tracefs is mounted
