These have been replaced by newer scripts located in the top-level
scripts/ directory.

This makes the following changes to the links message:
- Breaks user actions into steps
- Simplifies wordings
- Includes signature verification and bridge instructions

This restructures the GetTor help message. The message now includes:
- instructions to reply to the message for links
- available locales
- a valid example links request

This will make the locale parsing more restrictive so that, for example,
sending "i like fries" will not result in the locale "fr".

teor mentioned in ticket #23225 that some clients will top-post replies
without quoting the the text. This commit adds a test case for that.
Since the command detector is greedy, gettor parses the reply first.

Also added a test for bottom-posting.

This commit makes some changes and adds some tests to ensure that
valid replies to the gettor help message will contain links.
Non-valid replies should still return the GetTor help message.

This fixes an issue caused by gitlab repositories soft-delete for 7 days
before they are fully deleted. If we remove a repository in order
to upload new binaries, we need to be able to create a new one right
away. See https://bugs.torproject.org/33034

This fixes a bug where improperly formatted emails were not receiving
gettor replies. We should always reply to emails and default to sending
a help message if the request was invalid.

This also prioritizes sending links if both a valid links request and
the word help were sent. Several tests were added.

We were leaving connections to the database open, which causes some
calls to hang. This adds destructors to the SQLite3 class and the
classes that use it, and refactors some code to make one database
connection per class object. This also makes sure that the destructors
for objects that use databases are actually called.

The rest of GetTor uses the python sqlite3 package, and it's much
simpler to use and to test.

This will remove gettor requests from the requests database when they
are completed (rather than changing the status to 'SENT'). There's no
need to keep this information around, and we don't want to store
hashed email addresses as identifiers long term.

The only help message urged users to only specify 'en' as a locale. We
now support all locales for tor browser binaries.

This updates sendmail to get links and save stats for the user requested
locale. Right now all body translations default to english since we
haven't translated it yet.

This change expands the locale parse to have the following properties:
- if only the language code is given, choses the regionalization that
occurs first in the locale list (e.g., "en" --> "en-US"
- if regionalization for the language is *not* present, choses the
generalized language or a different regionalization (e.g. "pt-PT" -->
"pt-BR")
- parses both the subject and body looking for the most specific
regionalization
- defaults to en-US if no available language is found

This commit refactors build_request to prevent duplicate code. It
also moves the platforms definition to the parser constructor.

Before we were conflating the locales for the tor browser binaries with
the available locale for gettor email body localizations. This patch
checks our links database for available locales.

We haven't translated any es or pt strings, so use the English
translation for now until we update those files.

Removes tests that require access to secrets.

This commit fixes an edge case in which the config filename is never
declared if the config is set but the file does not exist on disk.

Created projects default to private, we need to set the visibility in
the script to make them public.

This fixes a bug where, if there were no errors in uploading binaries,
failure is referenced before it was ever declared.

This fixes an issue that occurred while running the new gitlab script on
the gettor machine. Newer library versions require the b64 encoded byte
string to be converted to ascii text.

This commit cleans up the script a bit by:
- making more detailed comments,
- streamlining the choice of remote repository
- printing all output to std error
- captilization consistency

We now have a separate script for both GitLab and Github endpoints.

Updated and refactored the script to upload tor browser binaries to the
gitlab remote using the GitLab REST API.

Add tests to check sent email messages.
