(cherry picked from commit 58270527d1)
Duplicate permissions definition with different group allows
privilege permission escalation to a different permission group.
Android studio and gradle plugin does not allow duplicate
permissions with different attributes, these tools only allow
if duplicate permissions are exact copies.
Also platform stores permissions in map at multiple places with
permission name as key. This suggests that we can disallow
duplicate permissions during package install/update.

Its existence allows implicit readParcelable calls to invoke a Parcel
operation with mismatched read/write data sizes, allowing someone to
swap out the data on a reparcel.
Internal classes will use writeIntentInfoToParcel, so this is safe to

This change ensures that while parsing a package, we require an explicit
wildcard in the queries->intent->data->host field. Prior to this change,
we were defaulting to wildcard when not provided. This resulted in,
e.g. someone trying to get visibility to just browsers actually getting
access to all packages that handle any web intent.

To mitigate a boot loop with reading a massive
install_sessions.xml file, this restricts the amount of
data that can be written by limiting the size of
unbounded parameters like package name and app label.
This introduces a lowered max session count. 50 for general
applications without the INSTALL_PACKAGES permission, and
the same 1024 for those with the permission.
Also truncates labels read from PackageItemInfo to 1000
characters, which is probably enough.
These changes restrict a malicious third party app to ~0.15 MB
written to disk, and a valid installer to ~3.6 MB, as opposed to
the >1000 MB previously allowed.
These numbers assume no install granted runtime permissions.
Those were not restricted since there's no good way to do so,
but it's assumed that any installer with that permission is
highly privleged and doesn't need to be limited.
Along the same lines, DataLoaderParams are also not restricted.
This will have to be added if that API is ever made public.
However, installer package was restricted, even though the API is
hidden. It was an easy add and may have some effect since the value
is derived from other data and passed through by other system
components.
It's still possible to inflate the file size if a lot of
different apps attempt to install a large number of packages,
but that would require thousands of malicious apps to be installed.

The camera API, MediaStore.ACTION_IMAGE_CAPTURE requires apps to pass
a content:// URI with write permissions to the camera. Unfortunately,
apps haven't been doing this and we only started hitting problems in R
for two reasons:
1. The FileUriExposedException that should crash apps when they try to
share file:// URIs acroos binder is skipped. This is because, the
image_capture intent is passed across binder as a field in a
ChooserActivity Intent and the child intents are not checked for
file URI exposed
2. Prior to R, when camera gets a file:// URI, camera issues a file
open(2) in its process. This open(2) succeeds because the camera had
write_external_storage permission which gave it write access to all
files on external storage
Now, camera targets R and (2) fails because camera does not have write
access to files owned by other apps. To workaround, we do the
following in the apps process when it targets < R:
a. When we detect a file:// URI for the camera in an Intent, we create
the file on disk if it is not already created.
b. Scan the file to insert it in the database and retrieve a
content:// URI
c. Replace the file:// URI with the content URI in the image_capture
intent
This works because, the system will ensure the camera is granted write
access to the content URI.

For Activity aliases, it's possible some values are already
set, which means they cannot be assumed to be 0, and can't be
overwritten if a attribute in the alias is undefined. For the
parsing v2 refactor, this was cleaned up to avoid
redundant != 0 checks, but those checks are indeed necessary.
This copies over the old logic and uses it exactly.
In some future cleanup, there should be a more structured way
of doing this, since it's not immediately obvious which values
are overridden or not. For example, description is always
overwritten even if no new value is provided in the alias.
This also fixes up the comparison tests and other bugs that
popped up because of them. The core issue was that when
auto-generating the dumpToString methods, the Alt+Insert
macro default selects all the fields in the current class,
but not all the parent classes, so some shared fields like
name/icon were not considered.
A notable case that was found when running the comparison tests
is that persistableMode is now "fixed" with v2. Previously,
a bug in PackageParser caused this value to be dropped if
the ActivityInfo object ever had to be copied. This is a change
from Q behavior, but there's no good way to reconcile this, and
it's better to be correct and consistent than broken, so this
fix was left in and excluded from the comparison tests.

On Pixel 2 devices, /product is a symlink to /system/product. The
product partition has a higher partition precedence than the system
partition so the app should be installed as a system app on the product
partition.
This change also unifies methods for checking whether a file is within
a partition so we will paths will always be canonicalized before the
check.
