Use isolated namespaces for app native libs
Linker namespaces provide necessary level
of isolation for application native libraries.
The native libraries will no longer be able to
mistakenly depend on platform private libraries
like /system/lib/libssl.so
This change creates one namespace for each instance
of class-loader and uses it when loading native libraries.

using default namespace and LD_LIBRARY_PATH if target
sdk version is <= 23. (currently set to 0 for testing)

Tidy up logging.
Move gVerboseMethods to CompilerOptions. Now "--verbose-methods=" option to
dex2oat rather than runtime argument "-verbose-methods:".
Move ToStr and Dumpable out of logging.h, move LogMessageData into logging.cc
except for a forward declaration.
Remove ConstDumpable as Dump methods are all const (and make this so if not
currently true).
Make LogSeverity an enum and improve compile time assertions and type checking.
Remove log_severity.h that's only used in logging.h.
With system headers gone from logging.h, go add to .cc files missing system
header includes.
Also, make operator new in ValueObject private for compile time instantiation
checking.

Add fast path for FindClass using the type dex file.
If we are using the PathClassLoader with a BootClassLoader
parent, we can handle the common case in the FindClass function
without needing to go back to java code.
Around 10% speedup measured of maps launch, could be noise due to
large variation of app launch times. Eliminates defineClassNative
from being anywhere near the top of sampling profiles.

ART: Throw StackOverflowError in native code
Initialize stack-overflow errors in native code to be able to reduce
the preserved area size of the stack.
Includes a refactoring away from constexpr in instruction_set.h to allow
for easy changing of the values.

Avoid some unnecessary use of stl types.
May be a minor performance win but really done for libc++ as this removes a
dependency on a library function whose prototype includes a std::string.

Object model changes to support 64bit.
Modify mirror objects so that references between them use an ObjectReference
value type rather than an Object* so that functionality to compress larger
references can be captured in the ObjectRefererence implementation.
ObjectReferences are 32bit and all other aspects of object layout remain as
they are currently.
Expand fields in objects holding pointers so they can hold 64bit pointers. Its
expected the size of these will come down by improving where we hold compiler
meta-data.
Stub out x86_64 architecture specific runtime implementation.
Modify OutputStream so that reads and writes are of unsigned quantities.
Make the use of portable or quick code more explicit.
Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the
mutator lock.
Refactor and share implementations for array copy between System and uses
elsewhere in the runtime.
Fix numerous 64bit build issues.

Refactor java.lang.reflect implementation
Cherry-picked from commit ed41d5c44299ec5d44b8514f6e17f802f48094d1.
Move to ArtMethod/Field instead of AbstractMethod/Field and have
java.lang.reflect APIs delegate to ArtMethod/ArtField.

Create separate Android.mk for main build targets
The runtime, compiler, dex2oat, and oatdump now are in seperate trees
to prevent dependency creep. They can now be individually built
without rebuilding the rest of the art projects. dalvikvm and jdwpspy
were already this way. Builds in the art directory should behave as
before, building everything including tests.
