Not only vendor libs, but also Android libs that are marked as
vendor_available are using SLOG*. Since both pure vendor libs and
Android libs available to vendors are using the same liblog headers for
VNDK, SLOG* needs to be visible via the headers.

Commit 795267d4c7 ("Removed cpusets/schedboost build time dependency.")
turned the cpusets and schedtune options into runtime
decisions.
However the kernel option which is mentioned in the
code comment (CONFIG_SCHEDTUNE) is very misleading
as it doesn't exist (CONFIG_SCHED_TUNE does exist)
and it doesn't describe the real functionality of
the method. schedboost_enabled() will still return
false if CONFIG_SCHED_TUNE is set in the kernel but
CONFIG_CGROUP_SCHEDTUNE is not.
So to clarify this, we need to change the comment
to reflect that CONFIG_CGROUP_SCHEDTUNE, which depends
on CONFIG_SCHED_TUNE, is required.

Although prctl is declared as a varargs function, in actuality it takes
unsigned long arguments (after the first int argument). This patch
ensures that the slack value passed to prctl is correctly sized.
Without this change, the 32-bit ARM compiler places the 64-bit slack
value in registers r2 and r3, but prctl expects the first argument to be
in r1. For kernel versions < 4.6, set_sched_policy has not been
correctly setting the timer slack value in 32-bit ARM code.

By setting vendor_available, the following may become true:
* a prebuilt library from this release may be used at runtime by
in a later releasse (by vendor code compiled against this release).
so this library shouldn't depend on runtime state that may change
in the future.
* this library may be loaded twice into a single process (potentially
an old version and a newer version). The symbols will be isolated
using linker namespaces, but this may break assumptions about 1
library in 1 process (your singletons will run twice).
Background:
This means that these modules may be built and installed twice --
once for the system partition and once for the vendor partition. The
system version will build just like today, and will be used by the
framework components on /system. The vendor version will build
against a reduced set of exports and libraries -- similar to, but
separate from, the NDK. This means that all your dependencies must
also mark vendor_available.
At runtime, /system binaries will load libraries from /system/lib*,
while /vendor binaries will load libraries from /vendor/lib*. There
are some exceptions in both directions -- bionic(libc,etc) and liblog
are always loaded from /system. And SP-HALs (OpenGL, etc) may load
/vendor code into /system processes, but the dependencies of those
libraries will load from /vendor until it reaches a library that's
always on /system. In the SP-HAL case, if both framework and vendor
libraries depend on a library of the same name, both versions will be
loaded, but they will be isolated from each other.
It's possible to compile differently -- reducing your source files,
exporting different include directories, etc. For details see:
