Make external API of class/module to be smaller, explicitely mark
all internal functions. Also annotate methods that are implemented
as the part of the parent class interface.

They are redundant in all pruned cases and sometimes even create some
problems, e.g., when one tries to jump through paragraphs in vi.

Prevent savemessage(), and savemessageflags() to occur in dryrun mode in
all backends. Still need to protect against deletemessage().

'set' is builtin since python2.6, so remove the imports. Also 'ssl' exists
since 2.6 and has everything we need, so no need for conditional import
tests here anymore.

When deleting many (eg 2000) mails using the SQLITE backend, this takes
a long time durig which OfflineImap can not be aborted via
CTRL-C. Thinking it had frozen permanently, I killed it hard, leaving a
corrupted db journal (which leads to awkwards complaints by OLI on
subsequent starts!). That shows that delete performance is critical and
needs improvement.
We were iterating through the list of messages to delete and deleted
them one-by-one execute()'ing a new SQL Query for each message. This
patch improves the situation by allowing us to use executemany(), which
is -despite still being one SQL query per message- much faster. This is
because rather than performing a commit() after each mail, we now do
only one commit() after all mails have been deleted.

They have the Repository() which contains the root, so no need to pass
it in as an extra parameter. Rename repository.LocalStatus()'s
self.directory to self.root for consistency with other backends.

It is possible to get the config parameter from the Repository() which is
set in BaseFolder, so we set self.config there and remove the various
methods and 'config' parameters that are superfluous.

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.

As this is essentially what it is, a set of values. This allows as
to do set arithmetics to see, e.g. the intersection of 2 flag sets
rather than clunkily having to do:
for flag in newflags:
if flag not in oldflags:
oldflags.append(flag)
Also some more code documenting.

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)

uid at a time (as a tuple). Deleting messages works now.

Test if sqlite is multithreading-safe and bail out if not. sqlite
versions since at least 2008 are.
But, as it still causes errors when 2
threads try to write to the same connection simultanously (We get a
"cannot start transaction within a transaction" error), we protect
writes with a per class, ie per-connection lock. Factor out the retrying
to write when the database is locked.

doautosave was a useless variable before (it was *always* 1). So we
remove the self.dofsync variable and store in doautosave whether we
should fsync as often as possible (which really hurts performance).
The sqlite backend could (at one point) use the doautosave variable to
determine if it should autocommit after each modification.

plus:
- Inherit LocalStatusSQLFolder from LocalStatusFolder
This lets us remove all functions that are available via our ancestors
classes and are not needed.
- Don't fail if pysql import fails. Fail rather at runtime when needed.
- When creating the db file, create a metadata table which contains the
format version info, so we can upgrade nicely to other formats.
- Create an upgrade_db() function which allows us to upgrade from any
previous file format to the current one (including plain text)
