The .txt format was the last place where the lowercase "builds" was used,
this converts references everywhere to be "Builds". This makes it possible
to load metadata YAML files with any YAML parser, then have it possible to
use fdroidserver methods on that data, like metadata.write_metadata().
The test files in tests/metadata/dump/*.yaml were manually edited by cutting
the builds: block and putting it the sort order for Builds: so the contents
should be unchanged.
```
sed -i \
-e 's/app\.builds/app.get('Builds', \[\])/g' \
-e "s/app\.get(Builds, \[\]) =/app\['Builds'] =/g" \
-e "s/app\.get(Builds, \[\]) =/app\['Builds'] =/g" \
-e "s/app\.get(Builds, \[\])/app.get('Builds', \[\])/g" \
-e "s/app\.get('Builds', \[\])\.append/app\['Builds'\].append/g" \
-e "s/app\['builds'\]/app.get('Builds', [])/g" \
*/*.*
```
Previously this was magically capturing the apps dict when passing it around as a
function. This also moved the code to the metadata module.
Add a test doing read_metadata where the linkresolver is used. This
happens when the apps we read have a [[app.id]] link to another app.
GitHub has specified FUNDING.yml, a file to include in a git repo for
pointing people to donation links. Since F-Droid also points people
to donation links, this parses them to fill out Donate:
and OpenCollective:. Specifying those in the metadata file takes
precedence over the FUNDING.yml. This follows the same pattern as how
`fdroid update` includes Fastlane/Triple-T metadata. This lets the
git repo maintain those specific donations links themselves.

The test file was generated using:
```python
import os, re, yaml
found = dict()
for root, dirs, files in os.walk('.'):
for f in files:
if f == 'FUNDING.yml':
with open(os.path.join(root, f)) as fp:
data = yaml.safe_load(fp)
for k, v in data.items():
if k not in found:
found[k] = set()
if not v:
continue
if isinstance(v, list):
for i in v:
found[k].add(i)
else:
found[k].add(v)
with open('gather-funding-names.yaml', 'w') as fp:
output = dict()
for k, v in found.items():
output[k] = sorted(v)
yaml.dump(output, fp, default_flow_style=False)
```
This converts float/int to string for things like commit: or versionName:.
For versionCode, which must be an integer, it throws an exception if the
data is any other type.
For cases like the OpenVPN vuln that was recently announced, it is useful
for fdroiddata maintainers to be able to mark builds that have known
vulnerabilities.
Like with the App class in the commit before, this makes it a lot
easier to work with this data when converting between the internal
formats and external formats like YAML, JSON, MsgPack, protobuf, etc.
The one unfortunate thing here is Build.update. It becomes
dict.update(), which is a method not an attribute.
build.get('update') or build['update'] could be used, but that would
be oddly inconsistent. So instead the field is renamed to
'androidupdate', except for in the .txt v0 metadata files. This better
describes what field does anyway, since it runs `android update`.
Build.update is only referenced in two places right next to each other
for the ant builds, so this change still seems worthwhile.
Python is heavily based on its core data types, and dict is one of the more
important ones. Even classes are basically a wrapper around a dict. This
converts metadata.App to be a subclass of dict so it can behave like a dict
when being dumped and loaded. This makes its drastically easier to use
different data formats for build metadata and for sending data to the
client. This approach will ultimately mean we no longer have to maintain
custom parsing and dumping code.
This also means then that the YAML/JSON field names will not have spaces in
them, and they will match exactly what it used as the dict keys once the
data is parsed, as well as matching exactly the instance attribute names:
* CurrentVersion: 1.2.6
* app['CurrentVersion'] == '1.2.6'
* app.CurrentVersion == '1.2.6'
