Some methods in header files of classes using SharedBuffer need
to be moved to the implementation files accordingly

Use external/safe-iop to check for overflows on arithmetic
operations.
Also remove an unnecessary copy of Vector/SharedBuffer from
codeflinger and use the copy from libutils instead.
Note that some of the unit tests are somewhat useless due to
test-runner limitations : gtest's ability to filter on abort message
doesn't work when combined with messages formatted by android's logging
system.

j is a ssize_t, which can go negative. If it goes negative,
the resulting multiplication of mItemSize*j doesn't make
any sense. Since the value is never used, just don't perform
the calculation if j < 0.

* Hashing functions rely on integer overflow behavior.
Mark those functions as safe.
* abort() if a passed in size_t value is greater than
UINT32_MAX. This can occur on 64 bit builds where size_t
is larger than uint32_t.
* Special case the index lookup for an empty sorted vector.
Without the special case, size() == 0, and size()-1 underflows.

1. When alloc or realloc failed in the function SharedBuffer::editResize,
it would return a NULL pointer, then mStorage would update to be 1 by
SharedBuffer::data() if no pointer check here, which is an obviously
wrong address, and would cause corruption when used it e.g. in capacity().
So add the pointer check here for the return value of SharedBuffer::editResize,
if it's NULL do not use it to update mStorage, to avoid the value of mStorage
polluted.
2. when alloc or realloc falied in _grow & _shrink function, mStorage keep
the original value, so mCount should not be updated here.
Otherwise, mStorage might be 0 but mCount>0, so a corruption would happend
when it try to delete items from the Vector since mCount>0.
