Dalvik : Increase the upper limit check for DexOpt Deps table

Increasing upper limit check for the Deps table as additonal
jars added causes the dalvik to crash while performing dexopt
on cached jar files. This is needed for passing cts test case
which is part of libcore.java.util.jar.DalvikExecTest class.

dalvik: use bioinc memmove

use memmove from bioinc if it is halfword atomic.

Fix synchronization when preparing ids.

Synchronized blocks were using different locks.
Replaced by a safer version: marking intern method synchronized.
This means synchronizing more than necessary but it had no
mesurable perfomance impact.

Dalvik: Ensure that the array length complies with the final specifier

JSR-133, which Android 4 should comply with, "final" fields should be
visible to all threads at the time the constructor exits, regardless of
synchronization. This behaviour should also apply to the array lengths
as they are regarded as equivalent in behaviour to "final" fields.
Non-final fields require explicit synchronization in Java for them to be
accessed correctly.

The Dalvik VM in Android ensures constructors for ordinary object behave
properly by inserting a memory barrier ("DMB") on their return if the
object's class has a "final" field.

The issue, however, is that while Dalivk inserts a barrier in
constructors, it doesn't during array create. A barrier ought to be
inserted in order to ensure an array's length is visible when the array
itself can be observed by other threads.

In order for Dalvik to be correct in respect to JSR-133 and the ARM
memory model, it should be modified to have a memory barrier after an
array is allocated and initialized, before it is visible to other
threads.

Retry mount() if it fails with EINTR

mount() may fail EINTR, and when it does this causes dalvik to crash.
Use the regular retry macro to avoid these problems.
