Transform ../ to dotdot/ for C++ generateds from .aidl source files.
This forces us to use one layer of indirection to calculate the build
rules for .aidl files, since we can no longer use a pattern rule.
This was tested by modifying system/tools/aidl's Android.mk to refer to
its .aidl files by going up two directories and then repeating the
directories again. When I print the build rules with $(info) I see that
dotdot/ appears in appropriate places (C++ paths, but not .aidl paths).

- For .l/.y source files, generate .c files; for .ll/.yy source files,
generate c++ files.
- Simplified the rules by adding the generated sources to
my_generated_sources.
- Simplified generated header file naming by always using .h extension
with bison's "--defines=" option.
- Removed the unnecesarry conditional inclusion to the generated
headers. Bison already automatically generates such things.

When USE_CLANG_PLATFORM_BUILD is not set, default will be clang/llvm.
USE_CLANG_PLATFORM_BUILD=false can be used to select gcc as default.

Host binaries may be run during the build process and the internal
implementation of the shared libraries makes a difference for the build
result. This change makes sure host tools get re-linked and re-run when
any of its dependency libraries gets updated.
DEX2OAT is such a host tool. We also changed DEX2OAT as full dependency
of dex-preoptimization, so we rebuild the odex files if DEX2OAT itself,
or any dependency libraries changed.

This was previously working because for some reason prebuilts/ndk had
a tangled mess of hand assembled symlinks that pointed lib -> lib64
for the multilib architectures.

Error out if there is a file listed in LOCAL_SRC_FILES_EXCLUDE but not in
LOCAL_SRC_FILES. This should catch typos or other mistakes that would
otherwise be missed.

There is currently an intentional incremental rebuild issue with
import_includes. export_includes might get updated with an identical
version, but we don't want to force everything downstream of it to
rebuild.
When BUILDING_WITH_NINJA==true, only update export_includes if it
changes, and use .KATI_RESTAT to only run downstream rules if it
changes. import_includes will only be updated if one of the
export_includes files is updated, so object files can have a normal
dependency on import_includes instead of an order-only dependency.
All downstream object files will now be recompiled if their imported
include paths change.

The export_includes file for a library needs to express a dependency on
all generated exported headers. For aidl generated headers, express a
dependency on the .cpp file instead, since the generator promises to
generate this file last. Unfortunately, the C++ headers generated from
a .aidl file depend on the contents of the file.

It is common for developers to generate/compile AIDL in a static
library, then link that library into an executable. When doing this,
developers need to export the generated headers.

Test: a refactoring of the aidl Android.mk shows this works

When a shared object is rebuilt, all dependent libraries and
executables are rebuilt. Such rebuild is unnecessary when there
is no interface change. With this patch, .toc files will be
generated for all .so files. The rule which generates .toc files
has ninja's restat=1 and .toc files are not changed ninja won't
rebuild dependent targets.

LOCAL_SRC_FILES_EXCLUDE will be used to filter files out of
LOCAL_SRC_FILES. A common usage will be to use
LOCAL_SRC_FILES_EXCLUDE_<arch> to remove a source file that will be
replaced with an arch-optimized version.

Ninja has an implicit dependency on the command being run, and kati will
regenerate the ninja manifest if any read makefile changes, so there is no
need to have dependencies on makefiles.
This won't catch all the cases where LOCAL_ADDITIONAL_DEPENDENCIES contains
a .mk file, because a few users of LOCAL_ADDITIONAL_DEPENDENCIES don't
include base_rules.mk, but it will fix the most common ones.

* commit '782b98eaa1c02d935b338f7317fef139067291bb':
Revert "Default to hiding libgcc symbols in each object."
Revert "Don't apply --exclude-libs for the host."
The Mac linker doesn't support this flag, and we don't actually need
it there anyway because we link dynamically to the system's compiler
runtime lib.
