Limit the number of IMAP connections to 1 per minute regardless of the reason of reconnection, but
allow one immediate retry. This is more reliable than ratelimiting only in error conditions because
ratelimiting can't be skipped by mistake. Anyway connections shouldn't be frequent in normal
operation mode.
send_webxdc_status_update JSON-RPC call
and corresponding Rust call sometimes fail in CI with
---
database is locked
Caused by:
Error code 5: The database file is locked
---
Adding more context to send_webxdc_status_update() errors
to better localize the error origin.
Otherwise when connection is lost IMAP may get into infinite loop
trying to parse remaining bytes:

Returning an error bubbles it up to `fetch_idle()`
which will call `trigger_reconnect()` and drop the connection.

I have removed the Makefile because modern Sphinx Makefile is just a
wrapper for `sphinx-build -M`:
3596590317/sphinx/templates/quickstart/Makefile.new_t
and sphinx-quickstart even has an option `--no-makefile`.
`make.bat` makes even less sense.
In `scripts/build-python-docs.sh` I use `sphinx-build` directly
without `make` wrapper.
Email addresses should generally be compared case-insensitively,
but there may be errors in comparison code.
To reduce the chance of problems, encode addresses
in Autocrypt and Autocrypt-Gossip in lowercase
to avoid propagating uppercase characters over the network
to other accounts potentially running buggy code.
If configured address is `Bob@example.net`,
but the message arrives adding `bob@example.net`,
Bob's device should still recognize it as addition of self
and fully recreate the group.
