- Rename `publicKeys` to `encryptionKeys` or `verificationKeys` depending on their use
- Rename `privateKeys` to `decryptionKeys` or `signingKeys` depending on their use
- Similarly, rename `toUserIDs` to `encryptionUserIDs` and `fromUserIDs` to `signingUserIDs`
Make all `read*` functions accept an options object, so that we can add config
options to them later (for #1166). This is necessary so that we can remove the
global `openpgp.config`, which doesn't work that well when importing
individual functions.
Furthermore, merge `readMessage` and `readArmoredMessage` into one function,
et cetera.
Instead of as modules.
Replace *.read with read*, *.readArmored with readArmored*, etc.
Replace cleartext.readArmored with readArmoredCleartextMessage.
Replace message.fromText with Message.fromText, etc.
