File descriptors remain open across an exec unless FD_CLOEXEC is
set. Add O_CLOEXEC to the open() call to prevent file descriptor
leakage.
In particular, the following program will eventually run out of
file descriptors:
int main(int argc, char **argv) {
printf("===== entering main =====\n");
ALOGW("entering main");
system("ls -l /proc/self/fd/");
execv(argv[0], argv);
printf("exec failed\n");
return -1;
}

Add a lock around android_fork_execvp to ensure no two threads can
execute it at the same time.
This is to help with http://b/8333626

When using device tree, platform devices may not have a
/devices/platform/ path prefix, but can be rooted in
/devices/.
Modify the platform device tracking code to store the device
path as well as the name. This way, when we create symlinks, we
can correctly skip the base platform device prefix and get to the
proper device node path.

This logic has been moved to platform/frameworks/base commit
8a0a929422682ba3eb6a205dc6c0638e68b909de and is no longer needed
here.
This reverts commit 01b1dee0ab.
Backtracing through eh_frame section is more effective allowing to reuse
ebp register for other purposes within routine. GCC with turned on
optimizations (-O1 and above) implicitly defines -fomit-frame-pointer
anyway. eh_frame sections are generated by default with GCC on any
optimization level.
This change implements remote unwinding (separate process unwinding).
Local unwinding is already implemented through _Unwind_Backtrace call
which is implemented in libgcc.

By now these sizes are very common, so make sure we support them.

goldfish is ported to linux-3.4 and have capability to run atrace.
But can't run atrace yet because debugfs is not mounted on boot time.
