c8206f24e1 remove support for the status_backend configuration option
Stop the run when this option is found. Migrating from the historical plain
text status cache is still supported.

3c42913120 sqlite: properly serialize operations on the databases
1. There is one database per folder and sqlite requires to serialize the
writings. Instead of locking at LocalStatusSQLiteFolder instance level,
introduce a new DatabaseFileLock object which is shared across threads. This
fixes the concurrent writes issues that some users might experience by
duplications or flags restored to the previous state.

2. Close the database only when we are sure no other threads will use the
connection on a *per-file* basis. Previous fix 677afb8d8f is wrong
because the same lock is shared for all the database files.

1410a391bc avoid removing of data when user removed a maildir
When a maildir is removed it must be considered new for the sync. However, the
local cache of the folder remains. This means the sync of the folder removes all
the missing emails.

Avoid loosing of data for users not aware of the local cache by removing any
pre-existing status cache of a folder when we actually want to create the
database.

Improve style.

1b954c3b4c Add ability to migrate status data across backends
If when we request a LocalStatus folder, the folder has to be created,
we look whether the other backend has data, and if it does we migrate
it to the new backend.

The old backend data is left untouched, so that if you change back say
from sqlite to plaintext, the older data is still there.  That should
not lead to data loss, only a slower sync while the status folder gets
updated.

09556d645e Adapt plain status folder to gmail labels stuff
* Implements Status Folder format v2, with a mechanism to upgrade an
    old statusfolder.

  * Do not warn about Gmail and GmailMaildir needing sqlite backend
    anymore.

  * Clean repository.LocalStatus reusing some code from
    folder.LocalStatus.

  * Change field separator in the plaintext file from ':' to '|'. Now
    the local status stores gmail labels. If they contain field
    separator character (formerly ':'), they get messed up. The new
    character '|' is less likely to appear in a label.

1b54b85f20 Reuse LocalStatus() folders rather than recreate instances
If we ask twice for a LocalStatusFolder via getfolder(), we would
get a newly created instance each time. This can lead to problems,
as e.g. write locks protecting files only work within the same Folder
instance. Make it so, that we cache all Folder instances that we have
asked for and hand back the existing one if we ask again for it,
rather than recreate a new instance.

Also, make getfolders() a noop for LocalStatus. We attempted to
derive the foldername from the name of the LocalStatusfile. However,
this is not really possible, as we do file name mangling
(".$" -> "dot", "/" -> ".") and there is no way to get the original folder
name from the LocalStatus file name anyway.

This commit could potentially solve the "file not found" errors, that people
have been seeing with their LocalStatusCache files. If we have 2
instances of a LocalStatusFolder pointing to the same file, our locking
system would not work.

b6807355b5 Implement ui.makefolder and abort repo.makefolder() in dry-run mode
IMAP, Maildir, and LocalStatus abort if in dry-run mode. IMAP and Maildir
will log that they "would have" created a new folder.

This will probably fail later on as we can not cache messagelists on
folder that don't exist, so --dry-run is not yet safe when new folders
have been created.

410e2d35e9 Set accountname in BaseFolder, and don't pass it in initialization
We passed in the accountname to all derivatives of BaseFolder, such as
IMAPFolder(...,repository,...,accountname), although it is perfectly
possible to get the accountname from the Repository(). So remove this
unneeded parameter. Each backend had to define getaccountname() (although
the function is hardly used and most accessed .accountname directly).

On the other hand BaseFolder was using getaccountname but it never defined
the function. So make the sane thing, remove all definitions from backends
and define accountname() once in Basefolder. It was made a property and not
just a (public) attribute, so it will show up in our developer
documentation as public API.

373e7cdbc1 Allow empty foldernames
Empty foldernames (as they could be created through nametrans) were
failing as the uidvalidity and status files names as determined by
folder/Base.py:getfolderbasename() lead to invalid file names ''.

Fix this by handling empty file names and translating them to '.' which
leads to the special file name 'dot'. (this special value existed before
and was not invented by this patch)
