261afd394b Add /data/storage_area to app data directories 
libselinux has special handling for the app data directories such as
/data/user/$userId/$pkgName and /data/user_de/$userId/$pkgName, because
their SELinux contexts are determined differently from "normal" files.

/data/storage_area/$userId/$pkgName will be a new app data directory
(with a different SELinux context, but determined through the same process).
THerefore, add it to the list of app data directories.

8f719500fd Add build flags for libselinux 
Consider /data/data as an app data directory (and skip any restorcon) if

      setfattr -x security.sehash /data/data;
      reboot, restorecon ignores /data/data

3d85f1e116 Use generic isSelector 
seapp_contexts supports multiple boolean attributes: isPrivApp,
isEphemeralApp, isIsolatedComputeApp, isSdkSandboxAudit,
isSdkSandboxNext, fromRunAs. Each of these exists to support a specific
labelling scenario from the framework. When a new predicate is required,
an update to libselinux is also required. This change generically
handles any attribute starting with "is" and maps it directly
(case-insensitive) to the same seinfo field.

It is assumed that only one of these is required at a time. An error is
raised if seapp_contexts contains multiple is-selector within one rule.
An error is raised if seinfo contains multiple is-selector.

The order for comparison between seapp_contexts is altered: an entry
with an is-selector will be prioritized over one with an unspecifed
is-selector. This is not quite the previous order (e.g., isPrivApp <
targetSdkVersion < fromRunAs), but it is understood that the previous
order was not intentional and emerged from the incremental contributions
to this library.

The boolean info.isPreinstalledApp is replaced by checking the first
byte of info.partition.

7fd89c00f7 Refactor the parsing of seinfo 
The seinfo string contains many attributes provided by the caller to
match an seapp_contexts rule. Its usage has evolved organically and now
contains multiple fields for various purposes.

Refactor the parsing of seinfo, relying on strtok as the string
informally follows the convention of using colons between attributes and
an equal sign to separate an attribute and its value. For instance,

  default:privapp:targetSdkVersion=10000:partition=system:complete

A new internal structure is introduced to capture the attributes. The
new parse_seinfo function replaces seinfo_parse (which only parsed the
first attribute, historically the original seinfo), get_partition and
get_app_targetSdkVersion.

The new function is expected to behave similarly to the previous code.
Unknown attributes are now logged, but still ignored. The "complete"
attribute is now interpreted (as the last attribute), but not required.

Unit tests are added to cover standard and edge cases.

Test: boot and verify denial logs
Test: atest --host libselinux_test
