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.

Nobody ever called acquire() so release() was always
equivalent to delete. Just use delete instead so that
people can use unique_ptr directly (or shared_ptr if
they really want refcounts).

The reference to NOT_USING_KLIBC appears to be the only one
in our codebase. This change also removes some cygwin specific
retry logic - all other supported platforms in this section
of the code should support mapping at an offset.
Note that i've reversed the sense of the check, we always sysconf
since that's recommended practice.

The actual bug is == instead of !=, but the real cause was me trying to be
too clever. This patch switches to much simpler code, and -- since the
intended use of this code is security anyway -- adds logging if anything
goes wrong.

This isn't particularly useful in and of itself, but it does introduce the
first (trivial) unit test, improves the documentation (including details
about how to debug init crashes), and made me aware of how unpleasant the
existing parser is.
I also fixed a bug in passing --- unless you thought the "peboot" and "pm"
commands were features...

Only two days in, and I'm already really regretting putting this code
somewhere that builds for Mac OS and Windows...

I knew I should have created a new library that doesn't build for the
Mac or Windows rather than adding to libutils...

Removed LOCAL_C_INCLUDES as the external/zlib headers are no longer
referenced by anything in libutils.
Removed unused host_commonLdlibs build variable. This was referenced
by the lib64utils host target which was removed in commit 03cc1f747
Tested compiling some of the projects that make use of libcutils
using a clean out dir with the folllowing targets
aosp_arm-eng : make -j16 logd dexdump
aosp-flouder-userdebug : make -j16 keystore vold libjavacore logd
aosp-x86_64-eng : make -j16 keystore vold libjavacore logd dexdump

The implementation of the FileMap destructor would
close the file, only on Windows, which did not match
the behavior on mac/linux.
This is because calling munmap does not close the file
descriptor. It must be closed separately, before or after
munmap.
On Windows, the file must also be closed manually,
before or after closing the mappingFile.
The change basically removes the closing file from
the windows-specific part of the destructor, to
make behavior more consistent on all platforms
where the caller to FileMap is responsible for closing
its own file (since FileMap receives an opened file).

The computed flattened size of the blob does not match the size used by the
flatten function when the last cached entry size is not 4 byte aligned.

There's an inherent race in trying to read out the thread name from
the system and the thread closing out on its own (and thus being removed
from procfs).
Try to handle this by formatting the thread name unconditionally with
the tid when getting the thread name fails (instead of dereferencing
NULL and crashing).
