- Disable icuio and layoutex.
- Hardcode UTF8 as charset (we always use utf8 and hardcoding him improve
performances)
- Do not include default utf headers
- Do not use `using namespace icu`
See http://source.icu-project.org/repos/icu/trunk/icu4c/readme.html#RecBuild
for more information about options.
Increment base dependencies version as we are compiling icu differently.
Make kiwix-build installable using pip.
Module is now called `kiwixbuild` because `kiwix-build` is not a valid
python identifier.
Also split toolchains in separated directory.
