New feature: HTTP API

[Peer Heinlein]

Thanks for the new HTTP API.

I get the API with some commands up and running, but I'm still not able
to create folder.

curl -k -H "Content-Type: application/json" -H "Authorization: Basic
secret" -d
'[["mailboxCreate",{"user":"user at example.org","mailbox":["INBOX/TEST"]},c01]]'
https://xxx.xxx.xxx.xxx.:8080/doveadm/v1

and also

curl -k -H "Content-Type: application/json" -H "Authorization: Basic
secret" -d
'[["mailboxList",{"user":"user at example.org","mailboxMask":["INBOX/TEST"]},c01]]'
https://xxx.xxx.xxx.xxx.:8080/doveadm/v1

doesn't work.

It /should/ create INBOX/TEST -- but doveadm always says it's "Invalid
JSON input".

What am I doing wrong?
