dillo Web browser

This is a major rewrite of dillo into C/C++, using
the FLTK2 library. This release comes with many
improvements: tabbed browsing, anti-aliasing,
different character sets, accepting compressed
pages, control over image loading, a smaller
footprint, nearly 50% smaller memory usage, fewer
dependencies, better table rendering, bugfixes, an
improved GUI, and many others.

This release comes with extensive work on the plugins side. It has a new dpip library, a new FLTK2-based GUI for downloads, a "data:" URI handler, an important bugfix in the FTP plugin, and a cookies server DPI that enables all Dillo instances to use cookies at the same time. There are many small fixes.

This a bugfix release that addresses a couple of security issues. It
also includes a new panel size option and a fix for the file dpi. Users
are advised to upgrade ASAP.

A very important memory leak involving pthreads'
stacks was fixed. This cuts virtual memory usage
(VSZ) by a factor ranging from 2 to 20, depending
on usage and the pthreads library implementation.
The generic parser was orthogonalized, which
brings some important enhancements and
improvements. The algorithm for parsing character
entities was redesigned. Lots of minor
improvements were made, and a security bug was
fixed. Users are encouraged to upgrade.

This version comes with a parser that's able to
use W3C's semantics plus some heuristics. This
improves the rendering of sites that deliver
non-valid HTML. It is expected to provide better
results than the venerable dillo-0.7.3, while
keeping the useful diagnostic messages of the bug
meter. A new unified API for handling data streams
inside dillo plugins was also introduced, and
every plugin was ported to it. Cookies,
redirections, and SSL were improved. (The latter
is still alpha and was disabled by default. Read
the FAQ to learn how to enable it).
