[libmicrohttpd] Update for websocket library

Hi @all,

some months ago I wrote an additional library for libmicrohttpd to add support 
for the websocket protocol.
Christian and Evgeny added that library with the configure flag 
“--with-experimental”.
There were still some tasks to do, but now I am finally done with them.

In the attachment you find the patch file, which must be applied to get the 
final version of the API.

For short it contains the following changes:
- added API documentation to libmicrohttpd.texi
- added websocket tutorial chapter to libmicrohttpd-tutorial and an much easier 
example for the tutorial
- added additional helper functions to ease the HTTP websocket handshake
- the code can now be compiled on Linux without errors :-)
- changed sha1.c and sha1.h to the files provided by Evgeny (I replaced those 
files in src/microhttpd_ws/ with the files from src/microhttpd/ - maybe there 
is a smarter way...?)
- removed dependency for "htons" and "htonl" (these functions are now 
implemented in MHD_websocket.c; no need for OS-dependent files anymore)
- added an additional test script for testing of the library with any 
webbrowser (for manual practice test)
- several bugfixes
- parameters renamed
- special things clarified (fragmentation, RNG for client mode)

The new version of the API is at some points incompatible with the old version, 
but since it was in an experimental phase and it didn't compile on Linux, I 
guess this shouldn't bother anyone.
From my point of view, I am now finished with the library and it could go out 
of experimental.
Maybe it would be good if anyone could give it a review.


Kind Regards
