If in invalid policy file is loaded check_seapp outputs:
Error: Could not lod policy file to db: Success!
The "Success" value is from errno, which is not manipulated
by libsepol. Also, load should have an a in it!
Hardcode the error message to:
Error: Could not load policy file to db: invalid input file!
Test: That when providing an invalid sepolicy binary, that the output
message is correct.

Input validation was hard-coded into a validation routine
that would check against type and key names in a scattered,
order dependent conditional code block.
This makes it harder than it should be to add new key value
pairs and types into checkseapp.
To correct this, we add a validation callback into the
static mapping. If the validation callback is set, the
existing validation routine will call this for input
validation. On failure, a validation specific error message
is returned to be displayed.

Ordering matters in fc files; the last match wins. In builds where
many BOARD_SEPOLICY_DIRS are set, the order of that list becomes
increasingly important in order to maintain a cohesive built
file_contexts.
To correct this, we sort the device specific file_contexts entries
with the upstream fc_sort tool.

Checkfc was treating 0 size fc files as a fatal error.
An empty fc file should be treated as "nothing to check"
so long as the -e option is passed.
We add this option, so we don't allow empty file_context
files to pass CTS checking.

Enable checkfc to check *_contexts against a set of valid attributes
which must be associated with all types in the contexts file that
is being checked.
Since it's imperative that checkfc knows which file its checking to
choose the proper attribute set, the -s option is introduced to
indicate the service_contexts file. The property_contexts file continues
to use the existing -p and file_contexts requires no specification, aka
it's the default.
Failure examples:
file_contexts:
Error: type "init" is not of set: "fs_type, dev_type, file_type"
service_contexts:
Error: type "init_exec" is not of set: "service_manager_type"
property_contexts:
Error: type "bluetooth_service" is not of set: "property_type"

Introduce "neverallow" rules for seapp_contexts. A neverallow rule is
similar to the existing key-value-pair entries but the line begins
with "neverallow". A neverallow violation is detected when all keys,
both inputs and outputs are matched. The neverallow rules value
parameter (not the key) can contain regular expressions to assist in
matching. Neverallow rules are never output to the generated
seapp_contexts file.
Also, unless -o is specified, checkseapp runs in silent mode and
outputs nothing. Specifying - as an argument to -o outputs to stdout.
Sample Output:
Error: Rule in File "external/sepolicy/seapp_contexts" on line 87: "user=fake domain=system_app type=app_data_file" violates neverallow in File "external/sepolicy/seapp_contexts" on line 57: "user=((?!system).)* domain=system_app"

rule_map_free() took as a parameter a boolean menu rule_map_switch
that was used to determine if it should free the key pointer that
is also in the table. On GLIBC variants, calls to hdestroy do not
free the key pointer, on NON-GLIBC variants, it does. The original
patch was meant to correct this, however, it always passes "destroy"
as the rule_map_switch. On GLIBC variants this is fine, however on
NON-GLIBC variants, that free was compiled out, and the free() was
handled by hdestroy. In cases of failure where the rule_map was not
in the htable, those key's were not properly free'd.

If a duplicate entry is found, rule_map_cmp() incorrectly
assumes that the lengths of the key value pairs should be
equal, when this is not true. The duplicate detection is
done on the input parameters, thus the lengths can be
different. This resulted in a duplicate error string
message of "do not match", instead of "match on all inputs".
Also, the file name printed that contained the error was
the output file, not the input file that contained it.

Address sanitizer requires using libc++ (apparently). We removed
libc++ from these projects since they were C and the SDK/CTS was not
able to find libc++.
If we're interested in continuing to use ASAN on these tools
(probably), we should turn libc++ back on once we're sure CTS won't
die.

Instead of displaying the boolean count, display a list of booleans
defined in the policy, if any. This makes sepolicy-analyze booleans
