The fallback android_filesystem_capability.h doesn't play nicely with
other kernel headers, since it #undef's __user. If we're building with
bionic (either for device or host), we use the same kernel headers, so
just use those.

ashmem buffers start with PROT_EXEC | PROT_READ | PROT_WRITE and can
have bits individually removed (but not added) through the
ASHMEM_SET_PROT_MASK ioctl. Test that removing prot bits more than once
works, and that the kernel blocks adding prot bits.
Also test that the complementary ASHMEM_GET_PROT_MASK ioctl returns the
expected prot mask.

ashmem has in-kernel handlers for lseek() and read(), but they aren't
currently being tested.
Add tests for various seeks on a buffer containing holes. If we land
inside data, then check that we read() the expected data at that offset.

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:
