Duktape 2.X: Update to Duktape 2.0.2. Note that DUK_OPT_XXX feature selection has been removed. This means we can't use `DUK_OPT_HAVE_CUSTOM_H`, so we need another way to tell duktape about our custom header. This means assembling our own duktape distribution with a duktape "tools/configure.py" invocation. Instructions for updating duktape have been added to NetSurf's `Docs/` directory. See: https://github.com/svaarala/duktape/blob/master/doc/release-notes-v2-0.rst#duk_opt_xxx-feature-option-support-removed

3. This generates a suitable set of duktape
sources in `/tmp/output`
5. Replace the `duktape.c`, `duktape.h` and
`duk_config.h` files in the netsurf source
tree (in `content/handlers/javascript/duktape`)
with those generated in `/tmp/output`.
