This is broken on all devices other than N9, and has no real path to fixing
it because there are so many different values already in use (41, 43, 47,
127), with no way to tell which you should use on any given device.

The PR_SET_TIMERSLACK_PID number has collided with upstream
changes a number of times, and thus the number is not consistent
between AOSP common kernel versions.
In 4.6+, the upstream kernel added equivalent functionaity via
the /proc/<tid>/timerslack_ns entry.
This patch changes the sched_policy logic to support
/proc/<tid>/timerslack_ns if its available, falling back to the
older PR_SET_TIMERSLACK_PID method if not.
NOTE: Eventually PR_SET_TIMERSLACK_PID usage will need to be
removed as it is likely to conflict with valid future upstream
PR_* entries.
Also add missing O_CLOEXEC to other open calls in this file.

Currently get_sched_policy() would only return foreground
or background, but not TOP_APP, since it's not looking
at CPUsets at all.
Fixing this makes testing easier, and it also corrects
the output of "ps -P" to show "ta" for current top app.

The code assumed that snprintf would never return a value less than
the passed in size of the buffer. This is not accurate, so fix all
of the places this assumptions is made. Also, if the name is too large,
then truncate just the name to make everything fit.
Added a new set of tests for this code. Verified that the old code passes
on the _normal and _exact version of the tests, but fails with the
FORTIFY error on the _truncated version of the tests. All tests pass
on the new code.

Unix and Windows both have functions to write multiple buffers to a
socket with a single call but they have very different signatures. This
CL creates some cross-platform functions to be able to perform these
operations in a uniform way, which will be required for upcoming

This CL also fixes some inconsistent spacing in the touched files.

Now that cutils has cross-platform socket functionality, we can
restructure fastboot to remove platform-dependent networking code.
This CL adds socket_set_receive_timeout() to libcutils and combines the
fastboot socket code into a single implementation. It also adds TCP
functionality to fastboot sockets, but nothing uses it yet except for
the unit tests. A future CL will add the TCP protocol which will use
this TCP socket implementation.
