Rather than later when retrieving them by IMAP, we determine the
"sync_this" value of a folder on Folder() initialization.
This also fixes a bug where folder structure was not propagated when
a folder was filtered out but included in the folderincludes list.

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.

If 'readonly' is True, folders shouldn't be created (regardless of
'createfolders' option). With old behavior, instead folders were always created
when 'readonly' is True (even if 'createfolders' was also False), which is a
serious bug (offlineimap was creating folders in all read-only repositories).
'createfolders' should only play a role if 'readonly' is False, in which case
folders should only be created if 'createfolders' is True.

By default OfflineImap propagates new folders in both
directions. Sometimes this is not what you want. E.g. you might want
new folders on your IMAP server to propagate to your local MailDir,
but not the other way around. The 'readonly' setting on a repository
will not help here, as it prevents any change from occuring on that
repository. This is what the `createfolders` setting is for. By
default it is `True`, meaning that new folders can be created on this
repository. To prevent folders from ever being created on a
repository, set this to `False`. If you set this to False on the
REMOTE repository, you will not have to create the `Reverse
nametrans`_ rules on the LOCAL repository.
Also implement a test for this

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.

While improving the test suite, I noticed that we would not create folders on
the remote in some cases when we should (yay for test suites!). This is because
we were testing the untransposed LOCAL foldername and check if it existed on
the remote side when deciding whether we should potentially create a new folder.
Simplify the code by transposing the LOCAL folder names in dst_hash, saving us
to create another confusing "newsrc" temp variable. Make the code a bit more
readable by using dst_name_t to indicate we operate a transposed folder name.
This now passes test 03 (using invalid nametrans rules) when test 03 would pass
before.

Rename variable src_name to src_name_t to indicate that it is the transposed
name. Also rather than testing the hash thingie, we can simply test for
"if source_name_t in dst_folders" now.

By default we sort folders alphabetically (for IMAP) according to their

allow the use of a cmp() function for foldersort. While going through, I

Subject: [PATCH] Only scan children in _getfolders_scandir if extension is set.
When sep is '/', MaildirRepository._getfolders_scandir recursively
checks sub-directories for additional maildirs. The old loop logic
always checked the top directory and its children. This lead to
children being found twice, once from their parent, with dirname
matching their directory name, and once from themselves, with a
dirname of ''.
This patch fixes the problem by only checking the top directory when
extension is not set (i.e. for the root directory).
When a new remote folder was detected, we tried to create the folder
locally on the Maildir and called repository.forgetfolders() to force a
new scanning of the Maildir. However, that implementation used the
inherited base function that did nothing. We simply needed to implement
forgetfolders() to set self.folder=None, so we would force a new read in
of the updated local folder structure.

1) Rename the unintuitive repository.syncfoldersto() to
sync_folder_structure()
2) We were checking if the local repository is readonly and then turning
off any folder creation. But as we can create folders on a remote
repository too, we need to be more fine grained here. Just don't create
a folder on the repository that is marked readonly=True.
This still does not do away with the error message that one currently
gets on missing local folders.

When sep='/' in a Maildir, we were doing a os.path.join(dirname,'') on
the top level maildir, which results in a "dirname/", so all our maildir
folder names had slashes appended. Which is pretty much wrong, so this
fixes it by only using os.path.join when we actually have something to
append.

The default parameter value was "None", and we were comparing that
directly to the imaplib2 value of is_readonly which is False or True, so
the comparison always returned "False".
Fix this by setting the default parameter to "False" and not
"None". Also convert all users of that function to use False/True.

If we create a new folder we would previously not update our folder
list, which led to us skipping the synchronization of those new folders
during the initial run (subsequent runs would pick it up).
Invalidate the folder cache when we create a folder during folder
structure sync. Regetting the whole list from an IMAP server might be
slightly suboptimal from a performance point, but it is easy and will
lead to consistent results. Hopefully we will not have to create new
folders on each new run.

Previously, getfolder() would always construct new MaildirFolder()
objects, independent of whether the folder exists or not. Improve the
function to:
1) Scan and cache the folders if not already done
2) Return the same cached object if we ask for the same foldername twice
3) Reduce a tiny bit of code duplication
This is important because we handle stuff like folderfilter in the
scandir function and if we discard the scanned dir and create a new
object on folderget(), we will lose the folderfilter information.
