Inconsistent behaviour between utf16_to_utf8 and utf16_to_utf8_length
is causing a heap overflow.
Correcting the length computation and adding bound checks to the
conversion functions.

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.

Sometimes it seems like we can get into a situation where we are
unable to remove an fd from the epoll set but it keeps sending us
events anyhow. Defensively rebuild the epoll set in this case
to prevent us from spinning forever.

Add a build id field to the header structure in blob cache. Add build
id support with reading and writing the cache. When the cache gets
written it writes the build id at the end of the header. When read it
checks to see if there is a match between the current version and the
version in the cache. If not, it invalidates the cache which would
typically only occur during an ota update. Also remove blob cache
from the host build.

When a file descriptor is closed before removing it from the
epoll set, it will normally be removed automatically from the
epoll set by the kernel. However if there exists a duplicate
then the original file descriptor may remain in the set and
continue to receive events until all duplicates have been closed.
Unfortunately due to kernel limitations we need to rebuild the epoll
set from scratch because it may contain an old file handle that we are
now unable to remove since its file descriptor is no longer valid.
No such problem would have occurred if we were using the poll system
call instead, but that approach carries others disadvantages.

Added code to protect against situations that may occur when a
Looper callback has the side-effect of closing the file descriptor that
it is watching before it returns. This code pattern is very
convenient for implementation but it does expose issues in how
the list of callbacks is maintained. In particular, we
need to watch out for file descriptors which have been reused.
This change may resolve previously unexplained ANRs associated with
log messages such as: "Error modifying epoll events for fd 44, errno=2"

The loop isn't technically idle at this time, it's just checking
whether any file descriptors have pending events. However it's
still a good signal as to whether the loop is alive.
