[ANNOUNCE] Sparse 0.3 released

[Josh Triplett <josh@freedesktop.org>]

I have tagged and tarballed a 0.3 release of Sparse, now available from
<http://kernel.org/pub/software/devel/sparse/dist/sparse-0.3.tar.gz>,
with sha1sum `1d868b29234176abd5f3f5463aad1f11d5268dc2`.

Note that the Sparse Git repository has moved to:

    git://git.kernel.org/pub/scm/devel/sparse/sparse.git

The old repository location will continue to work for now, but please update
any references you have to the old location.

Thanks to Christopher Li for contributing heavily to this release, including
several notable new features.  See the full changelog for details.

In addition to numerous bug fixes, cleanups, and new test cases, this release
includes several new visible features:

* A Sparse-based implementation of ctags, thanks to Christopher Li.  Now you
  can have a ctags that **actually parses C**.
* Sparse now correctly supports annotations on inline functions.
* The new `-ventry` option will make Sparse dump its internal linearized
  bytecode format.
* Sparse now parses the `__regparm__` attribute just like `regparm`, fixing a
  warning with pthreads from glibc 2.5.
* Sparse now interprets the integer size attributes `QI`, `SI`, `HI`, and `DI`,
  and their double-underscore variants.
* Sparse now supports attributes on labels, sometimes used to specify `unused`
  labels.
* Sparse now handles structure attributes between the structure keyword and the
  name, fixing many parse errors.
* Sparse now supports more than one command-line include file.
* The pkg-config file gets installed to its correct location under `lib`,
  rather than under `share`.

Notable internal changes:

* Fully table-driven attribute parsing.  This simplifies the C parser and makes
  it far easier to add new attributes to Sparse.
* Many internal cleanups, more information preserved for backends, more useful
  formats for that information, and lower memory usage.
* Fixed Sparse warnings about itself.
