perfetto: bump max cpu buffer size in ftrace
Turns out 2MB is too small and we can get overwrites in the ftrace
kernel buffer in this situation.
Bump to prevent potential issues from happening.

Remove warning suppressions and fix many casting bugs
This change removes most warning suppressions, in particular
from production code. In the past we inherit a bunch of -Wno-xxx
suppressions required to build gtest and libprotobuf headers.
Doing so, however, caused the suppressions to propagate back to
the translation units that were including any protobuf header
or any auto-generated .pb.h stub.
This change moves the gtest and probobuf header to be a
system include (-isystem vs -I). Doing so implicitly blacklists
any compiler warning on the headers.
This CL then re-enables warnings and deals with the fall out of
fixes that came out of this.

Mark file descriptors as FD_CLOEXEC
This prevents that they are leaked when exec(atrace).
When that happens, they cause unnecessary SELinux violations
because the new exec-ed process inherits them.

ftrace_reader: Add FtraceConfigMuxer
Move the logic for handling enabling/disabling/adjusting ftrace
settings into a new class: FtraceConfigMuxer.
Ftrace is a bunch of globaly modifiable persistent state.
Given a number of FtraceConfig's we need to find the best union of all
the settings to make eveyone happy while also watching out for anybody
messing with the ftrace settings at the same time as us.
Specifically FtraceConfigMuxer takes in a *requested* FtraceConfig
(|RequestConfig|), makes a best effort attempt to modify the ftrace
debugfs files to honor those settings without interupting other perfetto
traces already in progress or other users of ftrace, then returns an
FtraceConfigId representing that config or zero on failure.
To see which settings we actually managed to set you can call |GetConfig|
and when you are finished with a config you can signal that with
|RemoveConfig|.
