Fedor Indutny	bf25994308	tls: fix leak of WriteWrap+TLSWrap combination Writing data to TLSWrap instance during handshake will result in it being queued in `write_item_queue_`. This queue won't get cleared up until the end of the handshake. Technically, it gets cleared on `~TLSWrap` invocation, however this won't ever happen because every `WriteWrap` holds a reference to the `TLSWrap` through JS object, meaning that they are doomed to be alive for eternity. To breach this dreadful contract a knight shall embark from the `close` function to kill the dragon of memory leak with his magic spear of `destroySSL`. `destroySSL` cleans up `write_item_queue_` and frees `SSL` structure, both are good for memory usage.

tls: fix leak of WriteWrap+TLSWrap combination

Writing data to TLSWrap instance during handshake will result in it
being queued in `write_item_queue_`. This queue won't get cleared up
until the end of the handshake.

Technically, it gets cleared on `~TLSWrap` invocation, however this
won't ever happen because every `WriteWrap` holds a reference to the
`TLSWrap` through JS object, meaning that they are doomed to be alive
for eternity.

To breach this dreadful contract a knight shall embark from the
`close` function to kill the dragon of memory leak with his magic
spear of `destroySSL`.

`destroySSL` cleans up `write_item_queue_` and frees `SSL` structure,
both are good for memory usage.
