With non-empty root location, the canonic form of the root URL for a
kiwix server is now required to end with a slash (to match the situation
for an empty root location). This requirement enables usage of relative
URLs on the welcome page and resources/scripts loaded through that page.
A slashless root URL is redirected to the slashful version.
Now the root location is URI-encoded too.
In order to properly test this change the root location in the tests was
changed from "/ROOT" to "/ROOT#?" (or "/ROOT%23%3F" in URI-encoded form),
which is why this commit is so big.
- Before this change `InternalServer::build_redirect()` only URI-encoded the
article path, ignoring the book name and/or the root location components of
the URL.
- In order to be able to test this fix, corner_cases.zim was renamed to
contain a couple of special URL symbols in its filename. The
`create_corner_cases_zim_file` script was updated accordingly.
The file starts now to be too long.
- Move testing of the search html result in `test/server_html_search.cpp`
- Move common code used to launch server and so
in `test/server_testing_tools.h'
This is mainly code move with a small change:
Instead of setting the default PORT (8001) as a const int in the
`ServerTest` class, we now use SERVER_PORT.
SERVER_PORT must be defined before include `server_testing_tools.h`.
This allow several test to be run in parallele without trying to open
the same port.
