When Android processes fork from Zygote, we rewrite the command line
with a new name, eg. "system_server". When we do this, we should
fill the entire block with zeros to remove corrupted argument
information that may otherwise remain in the /proc/<pid>/cmdline buffer
and be seen in tools and stack dumps.
Fixed an issue where VM options could be overwritten after setting
the nice name if the name was too long.

Change app_process to be a symlink to the primary version
and have app_process32/app_process64 be the 32-bit/64-bit
versions respectively.
This will make it possible to use the primary zygote for
am/pm commands and other scripts that use app_process and
don't need a specific zygote.

The runtime expects them to exist before it's launched.
The boot image / art files are created during the first
zygote launch.

When app_process/zygote starts, make sure PR_SET_NO_NEW_PRIVS is set.
This prevents zygote spawned apps from acquiring new privileges
on exec.
In particular, this allows the CTS test
android.os.cts.SecurityFeaturesTest#testNoNewPrivs() to pass if ART is set
as the default runtime.

Use String8::isEmpty instead. Note that this code path is hit
only if the zygote calls ::exit, and that never happens unless
the VM invocation fails.

- Use different process names for the 32 / 64 bit zygote.
- Pass command line arguments correctly. The first unmatched
argument must be passed through to the java main class.

Query system properties for the list of ABIs and pass
it as a command line argument to ZygoteInit.
Also add a new Zygote command that returns this list of
ABIs to peers.

- Make copies of argc, argv before argv is potentially
overwritten with the process name.
- Allow multiple command line arguments to be passed to
ZygoteInit (this is required for some of the 64 bit
zygote work).
- Add an explanatory comment about how these argments
are processed.

These look like historical oddities, and weren't really being
used for anything useful.
Process:setArgV0 was being called by android.util.Process, but
that functionality can be moved directly into the implementation
of that class.

Use LOCAL_MULTILIB := both to build app_process64 instead of
duplicating the build rule.
Also causes PRODUCT_PACKAGES := app_process to install both
versions on 64-bit platforms, as the module names for both
app_process and app_process64 are now app_process.

On 64-bit platforms builds two copies of app_process, the 32-bit
app_process and 64-bit app_process64.

Stop working around bad applications by setting ADDR_COMPAT_LAYOUT.
ADDR_COMPAT_LAYOUT is undesirable because it reduces the amount of
address space available to an application.
The Android emulator, in both 4.3 and 4.4, does not set
ADDR_COMPAT_LAYOUT. Anyone needing to test their application on a
version of Android without ADDR_COMPAT_LAYOUT can use the emulator
and reproduce the failures.

This change disables all atrace tracing in Zygote immediately after it is
initialized. This is necessary because Zygote has no way to receive
notifications that the enabled trace tags have been changed. Tracing is
re-enabled when other processes fork from Zygote.

Different kernels seem to handle ADDR_COMPAT_LAYOUT differently,
sometimes passing it to its children, sometimes not. If it's not
passed to its child successfully, we can end up in a restart loop.
Instead of testing for the presence of ADDR_COMPAT_LAYOUT, use an
environment variable instead, which is handled more predictably.

For the emulator, we want people to see memory as it
actually is, not how we're hacking around buggy apps. Don't
set ADDR_COMPAT_LAYOUT on the emulator.
For reasons that I don't understand, personality(ADDR_COMPAT_LAYOUT)
does not persist across an exec on the emulator. app_main gets
into a tight loop restarting itself because of this. This change
also works around that bug.

This seems simpler and more contained, and I think the comment explaining

Since LOG_ALWAYS_FATAL is always fatal and code after it is by
definition unreachable, put the call after other diagnostic output.

executables have calls to some shared libraries without explicitly linking
them. Currently it works as linker links these libraries via dependencies of
other libraries. This is fragile and not the right thing to do.
