checkseapp, seapp_contexts: drop sebool= support.
SELinux policy booleans are prohibited in AOSP, so we can drop the
support for the sebool= input selector.

checkseapp: Detect duplicate keys in seapp_contexts entries.
Presently it ignores duplicate keys in seapp_contexts entries, e.g.
if you were to specify:
user=system seinfo=platform user=bluetooth domain=system_app type=system_app_data_file
checkseapp would ignore the duplicate and libselinux would end up using
the last value defined for the key in each line.

checkseapp: Detect duplicate entries within seapp_contexts.
Presently it only detects complete duplicates if you specify -s (strict),
which is not used in the external/sepolicy Makefile, and it allows
overriding earlier entries that have the same input selectors (e.g.
user=, seinfo=) with different values for the output selectors (e.g.
domain=, type=). Thus, a device/<vendor>/<board>/sepolicy/seapp_contexts
file can override the external/sepolicy definitions, and even a single
seapp_contexts file can contain duplicated or conflicting definitions.
Make it always check strictly, and prohibit either duplicates on the
input selectors (i.e. overrides) or complete duplicates (redundant).

Add isOwner= input selector for seapp_contexts.
Enable labeling apps differently depending on whether they
are running for the primary user / owner or for a secondary user.

Treat seinfo=default name=<anything> as an error.
check_app already checks for usage of name= entries
in seapp_contexts with no seinfo= specification to
link it back to a signer in mac_permissions.xml.
However, one can avoid this error by specifying
a seinfo=default which merely matches the default
stanza of mac_permissions.xml without actually ensuring
that it is tied to a specific certificate. Catch
that error case too.

Add support for and use new path= specifier in seapp_contexts.
Extend check_seapp to accept the use of the new path= specifier
in seapp_contexts and use it to ensure proper labeling of the cache
subdirectory of com.android.providers.downloads for restorecon.
After this change, restorecon /data/data/com.android.providers.downloads/cache
does not change the context, leaving it in download_file rather than
relabeling it to platform_app_data_file.
Depends on Iddaa3931cfd4ddd5b9f62cd66989e1f26553baa1.

Add sepolicy-analyze tool.
And also remove the unnecessary references to libselinux for
sepolicy-check, as it has no dependencies on libselinux.
Also enable -Wall -Werror on building all of these tools and
fix up all such errors.
Usage:
$ sepolicy-analyze -e -P out/target/product/<device>/root/sepolicy
or
$ sepolicy-analyze -d -P out/target/product/<device>/root/sepolicy
The first form will display all type pairs that are "equivalent", i.e.
they are identical with respect to allow rules, including indirect allow
rules via attributes and default-enabled conditional rules (i.e. default
boolean values yield a true conditional expression).
Equivalent types are candidates for being coalesced into a single type.
However, there may be legitimate reasons for them to remain separate,
for example:
- the types may differ in a respect not included in the current
analysis, such as default-disabled conditional rules, audit-related
rules (auditallow or dontaudit), default type transitions, or
constraints (e.g. mls), or
- the current policy may be overly permissive with respect to one or the
other of the types and thus the correct action may be to tighten access
to one or the other rather than coalescing them together, or
- the domains that would in fact have different accesses to the types
may not yet be defined or may be unconfined in the policy you are
analyzing (e.g. in AOSP policy).
The second form will display type pairs that differ and the first
difference found between the two types. This output can be long.
We have plans to explore further enhancements to this tool, including
support for identifying isomorphic types. That will be required to
identify similar domains since all domains differ in at least their
entrypoint type and in their tmpfs type and thus will never show up as
equivalent even if they are in all other respects identical to each other.

Generalize levelFromUid support.
Introduce a levelFrom=none|app|user|all syntax for specifying
per-app, per-user, or per-combination level assignment.
levelFromUid=true|false remains valid syntax but is deprecated.
levelFromUid=true is equivalent to levelFrom=app.
Update check_seapp to accept the new syntax.
Update seapp_contexts to document the new syntax and switch
from levelFromUid=true to levelFrom=app. No change in behavior.
