1968a0fca2 Improve appops parsing in dumpsys (#361)
Without this change the package doesn't get properly reset when a new
user starts.

See for example in this excerpt:

```
 1 |    Package com.android.bluetooth:
 2 |      READ_CONTACTS (allow):
 3 |        null=[
 4 |          Access: [pers-s] 2022-04-22 13:24:17.577 (-277d5h22m53s447ms)
 5 |        ]
 6 |      WAKE_LOCK (allow):
 7 |        null=[
 8 |          Access: [pers-s] 2023-01-24 17:45:49.712 (-1m21s312ms) duration=+3ms
 9 |        ]
10 |      GET_USAGE_STATS (default):
11 |        null=[
12 |          Reject: [pers-s]2022-04-22 13:23:53.964 (-277d5h23m17s60ms)
13 |        ]
14 |      BLUETOOTH_CONNECT (allow):
15 |        null=[
16 |          Access: [pers-s] 2022-04-22 13:23:53.988 (-277d5h23m17s36ms)
17 |        ]
18 |  Uid 1027:
19 |    state=pers
20 |    capability=LCMN
21 |    appWidgetVisible=false
22 |      LEGACY_STORAGE: mode=ignore
23 |    Package com.android.nfc:
24 |      WAKE_LOCK (allow):
25 |        null=[
26 |          Access: [pers-s] 2022-04-22 13:23:54.633 (-277d5h23m16s391ms) duration=+1s73ms
27 |        ]
```

Here the package "com.android.bluetooth" is not reset when in line 18,
so when "LEGACY_STORAGE:" in line 22 is encountered, it's added as
another permission to "com.android.bluetooth" with "access" set to
"ode=igno".

This PR fixes that by resetting the package whenever a new Uid is
encountered.

41db117168 Improve performance when checking URLs and domains
Some MVT modules such as the WhatsApp module can be very slow as it was taking a naive approach to look for IOCs. The code was checking URLs (potentially more than 100k) against
1000's of IOC domains resulting in a quadratic run-time with hundreds of millions of comparisons as the number of IOCs increases.

This commit add an Aho-Corasick library which allows the efficient search in a string (the URL in this case) for all matches in set of keys (the IOCs). This data structure is perfect for this use case.

A quick measurement shows a 80% performance improvement for a WhatsApp database with 100k entries. The slow path is now the time spent fetching and expanding short URLs found in the database. This
can also be sped up significantly by fetching each URL asynchronously. This would require reworking modules to split the URL expansion from the IOC check so I will implement in a separate PR.

Mobile Verification Toolkit (MVT) is a collection of utilities to simplify and automate the process of gathering forensic traces helpful to identify a potential compromise of Android and iOS devices.
It has been developed and released by the [Amnesty International Security Lab](https://www.amnesty.org/en/tech/) in July 2021 in the context of the [Pegasus project](https://forbiddenstories.org/about-the-pegasus-project/) along with [a technical forensic methodology and forensic evidence](https://www.amnesty.org/en/latest/research/2021/07/forensic-methodology-report-how-to-catch-nso-groups-pegasus/).

### Indicators of Compromise
MVT supports using public [indicators of compromise (IOCs)](https://github.com/mvt-project/mvt-indicators) to scan mobile devices for potential traces of targeting or infection by known spyware campaigns. This includes IOCs published by [Amnesty International](https://github.com/AmnestyTech/investigations/) and other research groups.
> **Warning**
> Public indicators of compromise are insufficient to determine that a device is "clean", and not targeted with a particular spyware tool. Reliance on public indicators alone can miss recent forensic traces and give a false sense of security.

> Reliable and comprehensive digital forensic support and triage requires access to non-public indicators, research and threat intelligence.
>
>Such support is available to civil society through [Amnesty International's Security Lab](https://www.amnesty.org/en/tech/) or through our forensic partnership with [Access Nows Digital Security Helpline](https://www.accessnow.org/help/).
More information about using indicators of compromise with MVT is available in the [documentation](https://docs.mvt.re/en/latest/iocs/).

# Development
The Mobile Verification Toolkit team welcomes contributions of new forensic modules or other contributions which help improve the software.
## Testing
MVT uses `pytest` for unit and integration tests. Code style consistency is maintained with `flake8`, `ruff` and `black`. All can
be run automatically with:
```bash
make check
```
Run these tests before making new commits or opening pull requests.
## Profiling
Some MVT modules extract and process significant amounts of data during the analysis process or while checking results against known indicators. Care must be
take to avoid inefficient code paths as we add new modules.
MVT modules can be profiled with Python built-in `cProfile` by setting the `MVT_PROFILE` environment variable.
```bash
MVT_PROFILE=1 dev/mvt-ios check-backup test_backup
```
Open an issue or PR if you are encountering significant performance issues when analyzing a device with MVT.

## Consensual Forensics
While MVT is capable of extracting and processing various types of very personal records typically found on a mobile phone (such as calls history, SMS and WhatsApp messages, etc.), this is intended to help identify potential attack vectors such as malicious SMS messages leading to exploitation.
