The Authorization header contains the Base64-encoded user name and
password. Remove this information from debug logs, unless the user
explicitly requests to keep them by using the --debug-raw flag.

When importing an iCal event via calcurse fails (i.e. does not return a
single object hash), do not write anything to the synchronization
database instead of blindly appending the entry, thereby potentially
corrupting the database.

This reverts commit efd76a0d995292e48f5466fccada4901618f7d97.
Passing passwords as command line arguments is not a good idea, since
they may appear in process listings which are potentially visible to
other users logged into the system.

It is best practice to use `/usr/bin/env python3` instead of a hard
coded path. This will search for "python3" in the PATH environment
variable.
Most Linux distributions install python to "/usr/bin". Most BSDs to
"/usr/local/bin".

When pushing objects, the unencoded uri path would be saved into the
sync.db. The unencoded path and the encoded path from the server would
be seen as two different objects, causing both to be resynced
unnecessarily.

Some parameters where swapped accidentally when reworking the diff

Instead of performing two synchronization steps (push/pull), split the
synchronization protocol into four steps:
1. Retrieve new objects from the server.
2. Delete local objects that no longer exist on the server.
3. Push new objects to the server.
4. Delete remote objects that no longer exist locally.
Each of the steps is performed by a separate function.

When a string is passed to HTTPConnection.request(), it is automatically

character set in the headers, we need to UTF-8 encode the request body
manually.

In commit 3eae7ce (Add --list-imported command line option, 2016-01-12),
we added an option to print the hashes of imported items to stdout.
Extend this command line option such that it dumps the items using the
specified formatting strings. With the new behavior it is, for example,
easier to check items for import errors.
Also, rename the option from --list-imported to --dump-imported (it is
not part of any official release yet so we do not need to care about
backwards compatibility).

Introduce pre-sync and post-sync hooks which need to be located under

with a CalDAV server.
Also, add an example post-sync hook and change the example post-save
hook such that it does not create tiny commits during synchronization.

In addition to storing ETag-hash tuples in the synchronization database,
also store the URI of each object. This makes the synchronization
process a bit more robust as we do not need to depend on ETags being
globally unique. It also allows us to detect conflicts which occur when
an object is modified locally and on the server at the same time.

This was partly fixed by 475c341 (calcurse-caldav: Fix late retrieval of
ETag, 2016-01-25). However, the case where the server does not return
ETag after creating a new item still wasn't handled properly. This patch
hopefully addresses this and also makes sure that the ETag header is
matched case-insensitively.
