A final(?) effort to reduce memory usage per flow (#1389)
Remove some unused fields and re-organize other ones.
In particular:
* Update the parameters of `ndpi_ssl_version2str()` function
* Zattoo, Thunder: these timestamps aren't really used.
* Ftp/mail: these protocols are dissected only over TCP.
* Attention must be paid to TLS.Bittorrent flows to avoid invalid
read/write to `flow->protos.bittorrent.hash` field.
This is the last(?) commit of a long series (see 22241a1d, 227e586e,
730c2360, a8ffcd8b) aiming to reduce library memory consumption.
Before, at nDPI 4.0 (more precisly, at a6b10cf7, because memory stats
were wrong until that commit):
```
nDPI Memory statistics:
nDPI Memory (once): 221.15 KB
Flow Memory (per flow): 2.94 KB
```
Now:
```
nDPI Memory statistics:
nDPI Memory (once): 231.71 KB
Flow Memory (per flow): 1008 B <---------
```
i.e. memory usage per flow has been reduced by 66%, dropping below the
psychological threshold of 1 KB.
To further reduce this value, we probably need to look into #1279:
let's fight this battle another day.
