GSOC project: #4334 Replace Mongoose with Civetweb

[Ayushman Mishra]

Greetings to all the respected mentors,
1. I saw there has been a lot of discussion regarding replacing
mongoose with civetweb (
https://lists.rtems.org/pipermail/devel/2016-April/014661.html ).
I think the basic outline of the project is like this
a. Completely removing mongoose and replace it with civetweb and make
it configurable in rsb
b. check the parameters and options available in civetweb and make it
usable for users in rtems.
c. making test-cases for civetweb (should be similar to mongoose)
d. documentation of using civetweb and web-server in general.
I would be very grateful to know what is the actual current status of
this project and the coding involved in it enough for a summer of code
project or some extra things should be added in it.

Also,
2. I have build bsp on rtems6 and a simple application is working
correct, but while trying to build libbsd package in rtems6
(../source-builder/sb-set-builder --prefix=$HOME/quick-start/rtems/6 \
  --host=sparc-rtems6 --with-rtems-bsp=erc32 6/rtems-libbsd ) I am
constantly getting build failed
RTEMS Source Builder - Set Builder, 6 (ade089253e70)

I also tried building all packages for bsp erc32
(../source-builder/sb-set-builder --prefix=$HOME/quick-start/rtems/6 \
    --with-rtems-tests=yes bsps/erc32) but after building for more
than an hour it also gave build failed error.

Thanks, Ayushman
