This switches:
BUILD_COPY_HEADERS / LOCAL_COPY_HEADERS
BUILD_HOST_EXECUTABLE
BUILD_HOST_SHARED_LIBRARY
BUILD_HOST_STATIC_LIBRARY
to errors by default. Devices can set
BUILD_BROKEN_USES_BUILD_HOST_EXECUTABLE (etc) to turn these errors back
to warnings. I've done that for all of our internal devices.

We've considered these deprecated for a while, and have reduced where
they may be used, but let's actually throw warnings and call them out
specifically now.

There are no common users left.
Also add some sanity checks to ensure that people don't attempt to use
LOCAL_IS_HOST_MODULE := true with the BUILD_(STATIC|SHARED)_LIBRARY
module types (I'm not sure it would work, but it definitely wouldn't be
good).

By resetting we lose LOCAL_*MODULE_STEM values for the second include
of the *_internal.mk.
We don't need to reset because we now store the default value to a
temporary variable my_*module_stem in configure_module_stem.mk.

When caught later, these just get turned into warnings with
unpredictable results, or non-obvious errors.

This change basically ported our target multilib to the host side.
It supports 2 host build modes: x86 and x86_64 multilib build.
For now you need to set "BUILD_HOST_64bit=true" to switch to x86_64
multilib build. Later we'll default to x86_64 build and have a flag
to force 32-bit only build, which may be needed by SDK build.
In host module definition, like in target ones, you can use the
following
LOCAL variables to set up multilib configuration:
LOCAL_MULTILIB: can be "both", "first", "32" or "64".
It also supports the same set of arch or 32-vs-64 specific LOCAL
variables.
By default, it builds only for the first arch.
To keep path compatibility, in x86_64 build files are still output to
out/host/linux-x86; Both 32-bit and 64-bit executables are in
out/host/linux-86/bin;
In x86_64 build 32-bit shared libraries are installed to
out/host/linux-x86/lib32
and 64-bit shared libraries are installed to out/host/linux-x86/lib;
32-bit object files are output to out/host/linux-x86/obj32 and 64-bit
object files
are output to out/host/linux-x86/obj.

LOCAL_MULTILIB replaces LOCAL_32_BIT_ONLY and
LOCAL_NO_2ND_ARCH, although both are still supported.
Set LOCAL_MULTILIB := 32 to always build a module 32-bit.
This is the same as specifying LOCAL_32_BIT_ONLY.
Set LOCAL_MULTILIB := first to always build a module for
the first architecture (64-bit on a 64-bit target, 32-bit on a
32-bit target). This is the same as specifying LOCAL_NO_2ND_ARCH.
Set LOCAL_MULTILIB := both to build for both architectures
on a mulitlib (64-bit) target.
If LOCAL_MULTILIB is not set libraries will default to "both",
and executables, packages, and prebuilts will default to building
for the first architecture if supported by the module, otherwise
the second.
Executables that set LOCAL_MULTILIB := both must set either
LOCAL_MODULE_STEM_32 and LOCAL_MODULE_STEM_64 or
LOCAL_MODULE_PATH_32 and LOCAL_MODULE_PATH_64 to specify how to
differentiate the install locations of the two versions.

Add four new variables for module makefiles:
LOCAL_MODULE_TARGET_ARCH specifies that a module is only supported for
one or more architectures. Any architecture not in the list will be
not attempt to build the module. The expected use case is prebuilts
that are only suitable for a single architecture, or modules like llvm
that need per-architecture support.
LOCAL_MODULE_UNSUPPORTED_TARGET_ARCH specifies that a module cannot be
built for one or more architectures.
LOCAL_MODULE_TARGET_ARCH_WARN and LOCAL_MODULE_UNSUPPORTED_TARGET_ARCH_WARN
are the same, but warn that the arch is not supported, which is useful
for modules that are critical but not yet working.
The logic for whether or not to build an architecture is fairly
complicated, so this patch consolidates it into module_arch_supported.mk

Using LOCAL_MODULE_PATH in a shared library module while building a
multiarch target will cause build rules for both architectures to install
into the same path. Warn and suggest LOCAL_MODULE_RELATIVE_PATH.

By default, an executable is built for TARGET_ARCH.
To build it for TARGET_2ND_ARCH in a 64bit product, use:
LOCAL_32BIT_ONLY := true
To skip a module for TARGET_2ND_ARCH, use:
LOCAL_NO_2ND_ARCH := true

The rules for the 2nd arch are set up in the second inclusion
of shared_library_internal.mk.
Intermediate fils of libfoo of the 2nd arch will be built into
$(PRODUCT_OUT)/obj_$(TARGET_2ND_ARCH)/SHARED_LIBRARIES/libfoo_intermediates/
and the built libfoo.so will be in
$(PRODUCT_OUT)/obj_$(TARGET_2ND_ARCH)/lib.

We are now unifying the NDK versions of unbundled native code to always
use the latest NDK.
We don't need the variable LOCAL_NDK_VERSION now.
To build native code with NDK, you need set just LOCAL_SDK_VERSION.

With this change, we can set LOCAL_EXPORT_C_INCLUDE_DIRS in the module
definition to export include dir paths.
Paths in LOCAL_EXPORT_C_INCLUDE_DIRS should be relative to the top dir
of the source tree.
If a library (shared or static) exports some include paths, any module
using it will import the include paths and add them to the compiler
command line.

To avoid race condition:
Say a module with LOCAL_NDK_VERSION built in the full source tree,
Before this change it may be linked against TARGET_GLOBAL_LD_DIRS/libc.so
that's being partially written out by the linker, because there is no dependency
between the module and TARGET_GLOBAL_LD_DIRS/libc.so.

This patch removes support for prelinking from the build system. By now, the
prelinker has outlived its usefulness for several reasons. Firstly, the
speedup that it afforded in the early days of Android is now nullified by the
speed of hardware, as well as by the presence of Zygote. Secondly, the space
savings that come with prelinking (measued at 17MB on a recent honeycomb
stingray build) are no longer important either. Thirdly, prelinking reduces
the effectiveness of Address-Space-Layout Randomization. Finally, since it is
not part of the gcc suite, the prelinker needs to be maintained separately.
The patch deletes apriori, soslim, lsd, isprelinked, and iself from the source
tree. It also removes the prelink map.
LOCAL_PRELINK_MODULE becomes a no-op. Individual Android.mk will get cleaned
separately. Support for prelinking will have to be removed from the recovery
code and from the dynamic loader as well.

LOCAL_NDK_STL_VARIANT can be set to system, stlport_static, stlport_shared
