To match the most common order in modern ruby projects: * Moved `attr_reader`s down below class methods. * Moved `#initialize` up above all public instance method `def`s. * Moved an method down with other public instance method `def`s. This commit should contain no other code changes.
Updated rdoc for #initialize: * Various stylistic changes, mostly for options and exceptions. * Added examples to demonstrate connecting with clear-text, TLS, and checking the greeting for "OK" or "PREAUTH". * Added links to OpenSSL::SSL::SSLContext rdoc.
* Extract four methods: * `convert_deprecated_options` * `start_imap_connection`: begins IMAP protocol on connected socket * `get_server_greeting`: wraps `get_response` with greeting specifics * `start_receiver_thread` * Various other small stylistic tweaks, e.g: grouped similar ivars. This _should_ be the result of a series of "pure" safe refactorings. All existing behavior should remain unchanged.
`Net::IMAP#ssl_ctx` will return the `OpenSSL::SSL::SSLContext` used by the `OpenSSL::SSL::SSLSocket` when TLS is attempted, even when the TLS handshake is unsuccessful. The context object will be frozen. It will return `nil` for a plaintext connection. `Net::IMAP#ssl_ctx_params` will return the parameters that were sent to `OpenSSL::SSL::SSLContext#set_params` when the connection tries to use TLS (even when unsuccessful). It will return `false` for a plaintext connection. Additionally, error handling for the arguments to `#starttls` was moved *before* sending the command to the server. This way a simple argument error will still raise an exception, but won't result in dropping the connection. Because `ssl_ctx` is also created ahead of time, this will also catch invalid SSLContext params.
