- Up to now the web browser used several fixed size arrays to hold the various types attribute data of the web page. This turned out to be way to inflexible for any non-trivial web page. Therefore now all attribute data is stored in a single buffer one after the other as they arrive from the parser only occupying the memory actually needed. This allows for pages with many links with rather short URLs as well as pages with few link with long URLs as well as pages with several simple forms as well as pages with one form with many form inputs.
- Using the actual web page buffer to hold the text buffers of text entry fields was in general a cool idea but in reality it is often necessary to enter text longer than the size of the text entry field. Therefore the text buffer is now stored in the new unified attribute data buffer.
- Splitting up the process of canonicalizing a link URL and actually navigating to the resulting URL allowed to get rid of the 'tmpurl' buffer used during form submit. Now the form action is canonicalized like a usual link, then the form input name/value pairs are written right into the 'url' buffer and afterwards the navigation is triggered.
- Support for the 'render states' was completely removed. The only actually supported render state was centered output. The new unified attribute buffer would have complicated enumerating all widgets added to the page in order to adjust their position. Therefore I decided to drop the whole feature as the <center> tag is barely used anymore and newer center attributes are to hard to parse.
In general it seems a bad idea to have two http-strings.c files as this precludes to have them both in the Contiki library. However as it stands it seems most reasonable to have one http-strings.c file be a clean superset of all usecases in order to allow them to run together in a single binary. As webserver/http-strings.c already contained strings not present in webbrowser/http-strings.c it seems reasonable to consider webserver/http-strings.c as the superset described. From that perspective it is appropriate to remove all strings from webbrowser/http-strings.c which are not used by the web browser in order to save memory otherwise wasted.
The tag <div> (in contrast to the tag <span>) is normally used to denote content placed on a line by its own. So it makes sense to trigger a newline when </div> is processed.
The "normal" web is moving forward quickly reducing the interoperability of the Contiki web browser to nearly zero. The Mobile Web fits the capabilities of the Contiki web browser much better. Modern smartphones don't need the Mobile Web anymore but there are large areas in world with rather low end mobile phones and limited mobile bandwidth where the Mobile Web will be necessary for quite some time.
From that perspective it is reasonable to increase the Contiki web browser's interoperability with the Mobie Web - namely WAP 2.0 aka XHTML MP. XHTML MP is delivered as MIME types 'application/vnd.wap.xhtml+xml' or 'application/xhtml+xml'. Therefore we (try to) parse the document if the MIME type contains the substring 'html' (which is true 'text/html' too).
functions for converting between host and network byte order. These
names are the de facto standard names for this functionality because
of the original BSD TCP/IP implementation. But they cause problems for
uIP/Contiki: some platforms define these names themselves (Mac OS,
most notably), causing compilation problems for Contiki on those
platforms.
This commit changes all htons to uip_htons instead. Same goes for
htonl, ntohs, and ntohl. All-caps versions as well.

Unfortunately I overlooked the dynamically created textentry fields for web forms. Changing their behaviour was a little more complicated as the length of the existing text was used to determine the size of the textentry field. Now this size is passed explicitly.
