This fixes 64-bit host compilation of libdex.

Change-Id: I364b624e12620f844cc7bbaa08e679c8a529f87c

- Changes signature of isDexOptNeededInternal. No behavioural
  changes are needed because dalvik only uses the first argument
  to the function (the "name") and dexopt is architecture agnostic.

- Changes dexOptGenerateCacheFileName to place dex files under
  /data/dalvik-cache/<instruction-set>. This allows us to avoid
  needing dalvik specific logic in the package manager and installd.

Code for managing Thread.sleep/wait used both !defined(__APPLE__) and
HAVE_POSIX_CLOCKS interchangeably to mean the same thing. That worked when
one or other was set but failed on host because neither were set and could also
fail if they were both set. This changed to use HAVE_POSIX_CLOCKS consistently.

The code that used this was spread across 4 separate files with quite a lot of
duplication so that has been replaced with a new method
dvmInitCondForTimedWait in Sync.cpp.

A few extra comments were added to make some things that were a bit confusing
clearer, hopefully.

Bug: https://code.google.com/p/android/issues/detail?id=68402

u4* args is a pointer to a flat array of 4 byte values,
so the "debugFlags" arg of postForkChild(long, int debugFlags)
is at args[2], not args[1].

The framework class com.android.internal.os.ZygoteInit
will call back to the runtime before / after the fork, so
that it can perform runtime specific bringup / teardown.

Currently unused. Note that ART does not have a native
definition of this function.

Fix typo in rule for libdvm_sv.  LOCAL_MODULE_UNSUPPORTED_ARCH
should be LOCAL_MODULE_UNSUPPORTED_TARGET_ARCH.

Change-Id: Iada67cc93560938d2a82a320cb88b7560e7db1b4

Set LOCAL_32_BIT_ONLY for all target modules
Use LOCAL_LDFLAGS_x86 instead of ifeq ($(TARGET_ARCH),x86)
Set dvm_arch to TARGET_2ND_ARCH instead of TARGET_ARCH on 64-bit
targets

This will allow "make checkbuild" to succeed on 64-bit platforms.

This prevents the generation of a new dexfile when an odex file already
exists when switching between Art and Dalvik.

Dalvik has no profiler, so we can safely ignore the
"defer" argument.

Keeps dalvik functional on master.

Replaced with the posix compliant pthread_condattr_setclock.
Unfortunately, mac OS doesn't support CLOCK_MONOTONIC
or (pthread_condattr_setclock) so we fall back to using
the "default" pthread_condattr_t value like we did earlier.

As promised, this is the cleanup patch-set which removes the
old native "fork and specialize" API, which has been replaced
by a slightly-enhanced one which can close the Zygote socket
descriptors in the Zygote child.

In order to prevent Zygote descriptors from leaking into the child
environment, they should be closed by the forked-off child process
before the child switches to the application UID.  These changes close
the descriptors via dup2(), substituting a descriptor open to
/dev/null in their place; this allows the Zygote Java code to close
the FileDescriptor objects cleanly.

This is a multi-project change: dalvik, art, libcore, frameworks/base,
and external/sepolicy are affected.  The CLs need to be approved
together, lest the build break or the software fail to boot.
