D27504: WIP: RFC: smb faster copy to local

[Harald Sitter]

sitter updated this revision to Diff 77343.
sitter added a comment.


  - rebase
  - move transfer impls to cpp
  - new unpop function to make the ring usage more consistent and make sure neither thread can overtake the other
  - new test for transfer tech. notably simulating imbalance in processing speed of the ring threads
  - segment now constructs from the file size instead of the segment size. this centralizes segment size code in the segment
  - make all transfers use a segment constructed with the relevant file size to get "smart" size calculation everywhere (ring buffer continues only for copyget and get)
  
  remote-to-remote copy is blocked on smb_context not being thread safe nor reentrant. unlikely to change any time soon. it's also blocking file change notification support for both kio and gvfs :(
