Also increase the default internal buffer size from 8kb to 32kb. We
have evidence that we're incurring a fair bit of "extra" disk write load
in various common circumstances like SharedPreferences, and this should
help eliminate that.

Some HALs, like a.h.graphics.mapper, are always passthrough and are
used by nearly all app processes. Preload those in Zygote to save app
startup time and share more pages between processes. This has the side
effect of also preloading a bunch of HIDL-related system and vndk
libraries that would also otherwise be loaded independently by every
app.
An earlier attempt at this change tried to preload the HAL via a
static initializer in libui.so (which is already preloaded, and which
is the immediate client of the HAL). But several other non-Zygote
processes also use libui.so, and didn't have SELinux permission to
access the device nodes used by the HAL. This version uses an explicit
call from Zygote to preload the HAL, instead of doing it implicitly.

Test: check that a.h.graphics.mapper is in /proc/`pid zygote64`/maps

New quota APIs are much faster than trying to measure manually, and
removing this last user of calculateDirectorySize() means we can
remove it once and for all.

Make sure that the preload method returns a boolean to avoid the
possibility of a NullPointerException or a ClassCastException during
the boxing / casting of its return value.

The biggest change is that padding will only appear above/below
service section, and at the start of the non-service section. For
this a bunch of changes to how padding is needed.
Also some other dimen changes for specs.

Fixes: 37913738
Before this change, we were throwing a checked exception on success
and returning on failure. This made it hard to figure out where / when
something was going wrong. This change switches things around to throw
a RuntimeException when something goes wrong and to return a Runnable
on success. This lets us make stronger assertions in both the parent
and the child process about their state and expected return values.
This change also upgrades the severity of several errors that we would
earlier just ignore. We will now reject the command and terminate the
connection to the client when we encounter these errors such as:
- Malformed arguments
- Any ZygoteSecurityException, such as thown thrown by
applyUidSecurityPolicy and applyInvokeWithSecurityPolicy.
- Any error in setting up pipes etc. to facilitate communication
with child processes.

Add an attribute android:classLoader which can be set to the name
of the classloader the base or split wishes to use. For now, this can
only be set to "dalvik.system.PathClassLoader" or
"dalvik.system.DelegateLastClassLoader". The current implementation
only allows the classloader to exist in the boot classpath but that
restriction can be loosened in a future change if necessary.

1. Fix the bug about foregroundActivityTime. It should take microseconds
as parameter and return microseconds
2. Use the min time of foregroundActivity time and Top time as "screen
time"
3. Hide bluetooth, wifi, idle but don't smear it

Before this change, ZygoteProcess.preloadPackageForAbi returned
as soon as the command was written to the zygote socket and not
after the preload completed. This meant that there was a small
window of time before the server side of the socket polled its FDs
where a second command could be written to the zygote socket. This
would lead to only one of the commands being processed and the
other being dropped. The client side of that socket would then wait
forever for a response and bring down the system once the watchdog
timeout was hit.
Example failure case :
--------------
system_server：send command(preloadPackage)
system_server：send command(fork)
zygote：poll & process command(preloadPackage) // the fork command is dropped.
Example of normal operation :
------------------
system_server：send command(preloadPackage)
zygote：poll & process command(preloadPackage)
system_server：send command(fork)
zygote：poll & process command(fork)
This change makes preloadPackageForAbi synchronous, which ensures
that each POLLIN event corresponds to precisely one command.

Several com.android.internal packages were being included in the
Javadoc build, even though they have no public APIs. Added a
package.html with the @hide tag to each of those packages, to
exclude them from the doc build.
Updated doc is staged to: http://go/dac-stage/reference/ ; verified
that the packages are now *not* in
http://go/dac-stage/reference/packages.html , and that package
summary files are not being generated for those packages.
