Re-merge "BigFile: Fixes, Tests and on-server Append support" 

This reverts

    4f3bb0c9    (Revert "BigFile: Fixes, Tests and on-server Append support")

and thus continues the story of

    193f5cdd    (BigFile: Fixes, Tests and on-server Append support)

and essentially restores the result of that merge.

Initial idea was to give people time to better see how to handle code
submisstion, but in the end Romain approved it as is.

Support storing huge file.
No convertion is allowed for now.
NOTE BigFile maintains the following invariant:
data property is either
- BTreeData instance, or
- str(*), or
- None.
(*) str has to be supported because '' is a default value for `data` field
from Data property sheet.
Even more - for
a) compatibility reasons, and
b) desire to support automatic migration of File-based documents
from document_module to BigFiles
non-empty str for data also have to be supported.
XXX(kirr) I'm not sure supporting non-empty str is a good idea (it
would be simpler if .data could be either BTreeData or "empty"),
but neither I'm experienced enough in erp5 nor know what are
appropriate compatibility requirements.
We discussed with Romain and settled on "None or str or BTreeData"
invariant for now.
