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

This reverts commit 193f5cdd, reversing
changes made to 4ee61a23.

Jean-Paul suggested we first better further review our code review / merging
procedures and use e.g. this particular merge request as a basis for that.

Thus I'm reverting this merge, so people could study and re-merge it
"properly".

~~~~

Please note: I could potentially rewrite master history so that there
would be a no merge commit at all, as e.g. my branch was not so far ever
merged at all. In contrast to draft branches, that is however a not good
practice to rebase, and thus rewrite, master history - what has been
committed is committed and we only continue.

So later to re-merge my branch, if it will not be changed, we'll need to
first revert this revert (see [1] for rationale), or alternatively I
could re-prepare my patches with different sha1 ids and they will merge
again the "usual way".

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.
