FTP/SMH should only connect on writing, not reading file operations

[markusmilkereit]

Opening FTP connections has some serious overhead and should be done as little as possible. Reading files should always work even without SMH, only writing operations really need an FTP connection.

Just a reminder :)

As we spoke yesterday, I will implement this in the SMHExtended aswell.
We can speed up a page impression using SMH from 3seconds to some milliseconds.

I am yet unsure of how to implement it though.

I will play around a little and provide a diff sometime this week.

Is SMHExtended an extension or a core change? Missed that part yesterday. I think most changes of SMHExtended could easily go into an extension, this change however should be in the core in any case.

It is an extension which is way too big to make it into core.
The current version also still might have bugs and is therefore IMO not yet stable enough to make it into the core anyway.
The next version is btw. already underway with new features like private key auth in addition to only user/pass auth.
Expect it to be released sometime this week.

Implemented in bfb6119. This is truly a major performance improvement if you are required to use the Safe Mode Hack! Especially in the front end, it drastically reduces the number of FTP connections.
