+/*
+ Design of this:
+
+ The idea is that the main run of applyChanges here makes two jobs:
+ the first sets the flags for encryption/signing or not, and the other
+ starts the encryption process.
+
+ When a job is run, it has already been removed from the job queue. This
+ means if one of the current jobs needs to add new jobs, it can add them
+ to the front and that way control when new jobs are added.
+
+ For example, the compose message job will add jobs that will do the
+ actual encryption and signing.
+
+ There are two types of jobs: synchronous and asynchronous:
+
+ A synchronous job simply implments the execute() method and performs
+ it's operation there and sets mComposer->mRc to false if the compose
+ queue should be canceled.
+
+ An asynchronous job only sets up and starts it's operation. Before
+ returning, it connects to the result signals of the operation
+ (e.g. Kleo::Job's result(...) signal) and sets mComposer->mHoldJobs
+ to true. This makes the scheduler return to the event loop. The job
+ is now responsible for giving control back to the scheduler by
+ calling mComposer->doNextJob().
+*/
+
+/*
+ Test plan:
+
+ For each message format (e.g. openPGP/MIME)
+ 1. Body signed
+ 2. Body encrypted
+ 3. Body signed and encrypted
+ 4. Body encrypted, attachments encrypted (they must be encrypted together, mEarlyAddAttachments)
+ 5. Body encrypted, attachments not encrypted
+ 6. Body encrypted, attachment encrypted and signed (separately)
+ 7. Body not encrypted, one attachment encrypted+signed, one attachment encrypted only, one attachment signed only
+ (https://intevation.de/roundup/aegypten/issue295)
+ (this is the reason attachments can't be encrypted together)
+ 8. Body and attachments encrypted+signed (they must be encrypted+signed together, mEarlyAddAttachments)
+ 9. Body encrypted+signed, attachments encrypted
+ 10. Body encrypted+signed, one attachment signed, one attachment not encrypted nor signed
+ ...
+
+ I recorded a KDExecutor script sending all of the above (David)
+
+ Further tests (which test opportunistic encryption):
+ 1. Send a message to a person with valid key but without encryption preference
+ and answer the question whether the message should be encrypted with Yes.
+ 2. Send a message to a person with valid key but without encryption preference
+ and answer the question whether the message should be encrypted with No.
+ 3. Send a message to a person with valid key and with encryption preference
+ "Encrypt whenever possible" (aka opportunistic encryption).
