Lower flock LOG(FATAL) to LOG(WARNING)
Failing to unlock a file should not be a fatal error.
The lock will usually be cleared right after this anyway by the file
being closed. Even if it isn't though this should not cause deadlocks
since most places either don't retry if they don't get the lock the
first time or are separate binaries (such as dex2oat) that are run
with external timeouts.

Do not fsync profiles on close
There's no need to fsync profile data right away. We get
many chances to write it again in case something goes
wrong. We can rely on a simple close(), no sync, and let
the kernel decide when to write to disk. This should
improve the I/O behavior of saving profiles.

Log the errno code for failed flock() invocations
ScopedFlock was asserting the success of flock()
invocation without logging errno. This CL adds the errno log
before the abort.

Add profman tool: responsible to process profiles
This pulls out profile parsing from dex2oat into a separate tool.
Some additional refactoring:
- better return codes
- dex2oat now accepts only one profile file
This is the first step towards support secondary dex files and
extracting profiles out of the code_cache directory.

ART: Track Flush & Close in FdFile
Implement a check that aborts when a file hasn't been explicitly
flushed and closed when it is destructed.
Add WARN_UNUSED to FdFile methods.
Update dex2oat, patchoat, scoped_flock and some gtests to pass with
this.

Runtime can now be set to require relocation
Add a pair of runtime flags -Xrelocate and -Xnorelocate that can force
the runtime to require that all files that are run are relocated, to
prevent attacks based on the known art base address.
Add support for running patchoat on oat files compiled without an image.
Change run-test to have new --prebuild and --relocate flags.

ART: Native support for multidex
Native support for zip files with multiple classesX.dex.
Works by explicitly looking for those files in ascending order. As
these files have no file system representation for themselves,
introduce synthetic dex locations: the name of the originating file
plus a colon plus the name of the dex file, e.g., test.jar:classes2.dex.
Opening a zip dex file will return all dex files in this way. This
keeps the changes to dex2oat minimal.
To hide multidex/synthetic names from the Java layer, let the handle
of dalvik.system.DexFile refer to a vector of DexFile objects. When
opening a location, test possible synthetic names and add them to the
vector. Thus, the original multidex jar in the classpath will be
associated with all embedded dex files.

Add locking around boot image generation.
If zygote aborts due to an error, it will restart and
spawn another dex2oat process while the old one is still
running. If this happens fast enough, the system will
eventually need a kernel reboot since neither the zygote
nor dex2oat are killable.
This brings boot image generation in line with dex2oat
generation, which uses a similar pattern of advisory
locking.
