From the commit message:
> When the structure is packed we should always expand when needed,
> otherwise we will add some padding between the fields. This patch makes
> sure we always merge bitfields together. It also changes the field merging
> algorithm so that it handles bitfields correctly.

Implement an enhanced variant of Crochemore and Perrin's Two-Way string searching algorithm, which reduces worst-case time from quadratic (the product of the string and pattern lengths) to linear. This applies to forward searches (like``find``, ``index``, ``replace``); the algorithm for reverse searches (like ``rfind``) is not changed.

From the SQLite 3.5.3 changelog:
sqlite3_step() returns SQLITE_MISUSE instead of crashing when called
with a NULL parameter.
The workaround no longer needed because we no longer support
SQLite releases older than 3.7.15.
Exit code is now 1 instead of 0. A message is printed to stderr instead of stdout. This is
the proper behaviour for a tool that can be used in scripts.
The note about the GIL was buried pretty deep in the threading documentation,
and this made it hard for first time users to discover why their attempts
at using threading to parallelizing their application did not work.
In this commit, the note is moved to the top of the module documention for
visibility.
