Before 3434d1940 the return values of libnotmuch functions were
declared as c_void_p and the code checking for errors compared the
returned value to None, which is the ctypes equivalent of a NULL
pointer.
But said commit wrapped all the data types in python classes and the
semantic changed in a subtle way. If a function returns NULL, the
wrapped python value is falsish, but no longer equal to None.
Backported from master to 0.11.

All strings are unicode strings in python 3 and the basestring and
unicode types are removed hence the need for a specialized version.

Recent changes introduced lots of unicodification of strings, mostly in
the form of .decode('utf-8', errors='ignore'). However, python 2.5 does
not like the errors keyword argument and complains. It does work when
used as a simple arg though, so that's what this patch does.

Formerly Message.get_replies() returned an iterator or None forcing
users to check the result before iterating over it leading to strange
looking code at the call site.
Fix this flaw by adding an EmptyMessagesResult class that behaves like
the Messages class but immediatly raises StopIteration if used as an
iterator and returning objects of this type from Message.get_replies()
to indicate that there are no replies.
Since 2b01161191, Message.__str__ doesn't
construct a hash containing the thread data before
constructing the formatstring. This changes the formatstring
to accept positional parameters instead of a hash.
Now that types are checked correctly, we also need to make sure that all the
arguments actually are instances of these types. Otherwise the function calls
will fail and raise an exception similar to this one:
ctypes.ArgumentError: argument 3: <type 'exceptions.TypeError'>: expected
LP_LP_NotmuchMessageS instance instead of pointer to c_void_p
We were not returning anything at all, which does not match the API
documentation. Fixed. Thanks to Patrick Totzke for the heads up.

Add type information to the ctypes._FuncPtr wrappers and
use the wrapper classes instead of c_void_p for pointers
to notmuch_*_t.
This enables the ctypes library to type check parameters
being handed to functions from the notmuch library.

Technically, this is a superfluous change, as the self.status variable
currently gets set in NotmuchErrors's __new__ function. However, in the
long run I would like to get rid of the weird __new__ implementation which
might be somewhat confusing for users (NotmuchError(status) returns a
different class, e.g. OutOfMemoryError)

Two new wrappers:
Notmuch::Database.find_message(id) => Notmuch::Message or nil
Notmuch::Database.find_message_by_filename(path) => Notmuch::Message or nil
Previously, the Filenames generator only yielded *one* filename before
returning, making Message.get_filenames() behave as Message.get_filename(). This
commit fixes this incorrect behavior: now the generator yields all the
filenames, as expected.
Add some smart magic, so that when we invoke a
NotmuchError(STATUSVALUE), a nicely derived subclass is created, e.g. a
OutOfMemoryError. This way users can easily distinguish between error
types, while still catching NotmuchError.
I have tested this, and hope it works for others too.

To make the exception handling more effective in code using the
python bindings it is necessary to differentiate between the
different kind of failures.
Add an exception class for each status code and add a decode
classmethod to the NotmuchError class that acts as a factory.
Import the new classes in __init__.py so they can be easily
imported by anyone.

Raising Exception is considered bad since the only way to catch
it is to do 'except Exception'. Raising a TypeError is more
appropriate.
Since the format parameter has already been validated, checking
it again is not necessary. Simplify this conditional.

According to the common Ruby function naming convention, potentially
dangerous functions or functions which operate on the object itself are
suffixed with an exclamation mark. Both of these are true for object
destroying functions.
The following modules are affected:
- Notmuch::Directory
- Notmuch::FileNames
- Notmuch::Query
- Notmuch::Threads
- Notmuch::Thread
- Notmuch::Messages
- Notmuch::Message
- Notmuch::Tags
If we use unicode objects, libnotmuch would not cope with null bytes in
the byte array, so we need to make sure they are nicely formatted as
utf-8.
Introduce a helper function _str which does this throughout the code.

we now have three files to keep in sync. That seems wrong, but I guess
we will live with it for now.
The main problem is that the python code is distributed separately, so
it can't get the version from 'version'.
The choice ~rcX is for convenience with debian versioning.
Decode and Encode from/to unicode objects as required to be able to take
unicode path names. Previously we would error out when an unicode object
were handed it.

Importing the notmuch module in setup.py is a no-no, and we want
to auto-generate the version number in the release process.
Outsource __VERSION__ to the new version.py which contains nothing else
and which can therefor easily be autogenerated. Have setup.py read in
the file via execfile and test if importing the version number actually
worked.
This should make all happy.

This reverts commit 8826fc2d7b.
It seems that importing the module in setup.py is controversial at best,
as it will fail for users that don't have all dependencies
installed. This was the case in e.g. the Ubuntu autobuilder, so building
notmuch failed. The plan is to create an autogenerated setup.py that can
be used for version information.

len() exhausts the tag iterator and e.g. list() or "".join(tags)
implicitly call len() if existing and then failing. So, we remove
Tags.__len__().
If you need to know the number of tags a message has, do use
len(list(tags)). It would be nicer to be able to support len() directly...
