Avoid accessing TLS in rsClearObject()
Bug: 27874893
Bug: 27925095
rsClearObject() may be called on rsContextDestroy() in the JNI thread,
where TLS is not initialized.
This also reverted Icca50fade1199b6f530f963e9e694366b7d8cf67 that
made rsContextDestroy() go through the FIFO. rsContextDestroy() must
happen off the FIFO, since it joins the FIFO consuming thread.
Both the rsClearObject() change and the rsContextDestroy() revert need
to go together to make RenderScript and Camera CTS tests pass. Hence
this single CL for both changes.

Multithreaded execution of certain general reduction kernels; reduction test overhaul.
A reduction kernel is eligible for multithreaded execution if it has a
combiner function and it is launched over a 1D iteration space.
Note: Properties debug.rs.reduce-accum and debug.rs.reduce-split-accum
are added for debugging multithreaded reduction.
The following changes are made to reduction tests in RsTest:
- Overhaul the test framework -- now data-driven, and can execute the same
test multiple times with different seeds and input sizes, features
separate sets of quick correctness tests, full correctness tests,
and performance tests. (Performance tests are not run by default.)
- Report timing information for test execution.
- Report more information for fz* kernel testing.
- Remove dp kernel testing -- this involved floating-point arithmetic
which is not guaranteed to produce identical results between java
and rs or for different rs multithreaded executions.
- Add sumgcd kernel testing. This is intended to be representative of
a compute-heavy kernel.
- findMinAndMax kernel testing must compare cell value not cell index
-- two or more cells might have the same min or max value, and java
and various rs multithreaded executions are not guaranteed to find
the same cell.
- Fix bug in findMinAndMax kernel's combiner function. (It behaved
incorrectly when operating on an accumulator datum that has been
initialized but never passed to the accumulator function.)
- RsTest now requests largeHeap.

Update RS driver to support extraction of global variable properties.
Bug: 20306487
This patch adds some new enums to classify properties (such as "static",
"constant", and "pointer") for global variables. The reference driver
is also extended to provide methods to examine these properties (when
the bitcode is compiled with bcc).

Add a way to link against different driver names.
The existing linker path hard-coded "-lRSDriver" into the command line, but
this won't work for partner drivers that have a different implementation
loaded. In order to still properly handle use of the CPU driver, this needs
to change depending on whether we actually loaded an OVERRIDE_RS_DRIVER or
not.

Add RSGlobalInfoPass information to RS driver.
Bug: 20306487
This change enables vendor drivers to configure support for including
additional information about global variables in the emitted CPU code.
This information includes the number of total global variables, the
names of these variables, the addresses of these variables and the
sizes of these variables. The driver can also select whether the
information includes constant (immutable) globals or not.
The reference driver defaults to embedding information about each of
the existing, non-constant global variables.

Dedup checksum calculation routines
I introduced a separate routine to cacluate checksum for ScriptGroup
in my previous CL, in addition to the one we use for regular scripts.
This CL removes the new one and uses the old one.
While I am on it, I made some other minor changes, e.g., changing
mBuildChecksum in RsdCpuScriptIml from char* to uint32_t, and a few
other minor cleanups in ScriptGroup2 implementation.

Runtime support for Script Group as single module
Also made two other cleanups:
- Changed KernelID/InvokeID into IDBase in class Closure
Rather than having two fields in class Closure, one of type ScriptKernelID and
the other InovkeID, use a single field of the common base class IDBase. Added a
boolean field to indicate whether it is kernel or invoke, since -fno-rtti is on.
- Removed user pointer from CPU closure

Add build fingerprint and ensure match on .so load
bug 19216507
If ro.debuggable system property is set,
- Compute the Adler32 checksum of bitcode, compiler arguments, bcc,
libclcore files.
- On shared object load, check that there is an embedded checksum value
in .rs.info and it matches the value computed in the previous step.
The .so is not loaded if the checksums don't match.
- If invoking bcc, pass the checksum as an argument.
If ro.debuggable is not set, a constant checksum is added to .rs.info.
But it is never checked.
