and -Wunused-but-set-parameter for GCC builds.

Move DISALLOW_COPY_AND_ASSIGN to delete functions. By no having declarations
with no definitions this prompts better warning messages so deal with these
by correcting the code.
Add a DISALLOW_ALLOCATION and use for ValueObject and mirror::Object.
Make X86 assembly operand types ValueObjects to fix compilation errors.
Tidy the use of iostream and ostream.
Avoid making cutils a dependency via mutex-inl.h for tests that link against
libart. Push tracing dependencies into appropriate files and mutex.cc.
x86 32-bit host symbols size is increased for libarttest, avoid copying this
in run-test 115 by using symlinks and remove this test's higher than normal
ulimit.
Fix the RunningOnValgrind test in RosAllocSpace to not use GetHeap as it
returns NULL when the heap is under construction by Runtime.

Don't do "if (ptr)". Use const. Use DISALLOW_COPY_AND_ASSIGN. Avoid public
member variables.
Move ValueObject to base and use in ELF builder.
Tidy VectorOutputStream to not use non-const reference arguments.

This saves more than 0.5s of boot.oat compilation time
on Nexus 5.

TODO: Move other stuff to the scoped allocator. This CL
alone increases the peak memory allocation. By reusing
the memory for other parts of the compilation we should
reduce this overhead.

The classes and the names are very much inspired by V8/Dart.
It currently only supports the RETURN_VOID dex instruction,
and there is a pretty printer to check if the building of the
graph is correct.

- Turn the compile-time flags for generational mode into a command
  line flag.

- In the generational mode, always collect the whole heap, as opposed
  to the bump pointer space only, if a collection is an explicit,
  native allocation-triggered or last attempt one.

Memory usage regressed since we didn't properly update
concurrent_start_bytes_ when changing collectors.

Bug: 12034247

Change-Id: I1c69e71cd2919e0d3bf75485a4ac0b0aeca59278

Added a case for BumpPointerSpaces. Confirmed working non-debug.
Should also work in debug builds.

Bug: 11830794
Change-Id: I12053ff16eec403dcd4a780e13095e3212a77132

Can be used for running tests or benchmarks with semispace,
marksweep or concurrent marksweep.

Also, move dex file verifier messages out of logs.
In the process the ClassLinker::dex_lock_ needed tidying to cover a smaller
scope. Bug 11301553.

Needed to update cpplint to handle const auto.

Fixed a few cpplint errors that were being missed before.

Replaced most of the TODO c++0x with ranged based loops. Loops which
do not have a descriptive container name have a concrete type instead
of auto.

Move dlmalloc include inside of cc file.

Change-Id: Ic36bdbf9fa964b93a23d1a45f603bab1bf9583d7

Adds a new stl compatible allocator that is used in most GC data
structures. When the data structures allocate and free memory, it
lets the heap know of how much memory was allocated or freed. Using
this info, we dump the approximated stl data structures memory usage
when a sigquit occurs.

The allocation tracking can be disabled with a compile time boolean
flag to remove performance impact.

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.

This isn't going to be as reliable as debuggerd because we're running inside
the crashed process. We could always build debuggerd for the host, and have
something to call out to that. But for now, this gives us most of the
information most of the time...

Runtime::Abort takes arguments so it can provide less misleading log output,
but this shouldn't matter to callers because they should be using LOG(FATAL)
anyway.

This patch also fixes an errno/errno_ mixup in the logging code.
