Make ClickHouse compilable and runnable on risc-v 64
So far only basic functionality was tested (on real hw),
clickhouse server runs, exceptions works, client works,
simple tests works.
What doesn't work:
1. traces - they are always empty
2. system.stack_trace only have first frame
* replace exit with assert in test_single_page
* improve save_raw_single_page docs option
* More grammar fixes
* "Built from" link in new tab
* fix mistype
* Example of include in docs
* add anchor to meeting form
* Draft of translation helper
* WIP on translation helper
* Replace some fa docs content with machine translation
* add normalize-en-markdown.sh
* normalize some en markdown
* normalize some en markdown
* admonition support

* lightly edited machine translation of introdpection.md

* WIP on translation utils
* Normalize ru docs
* Normalize other languages
* some fixes
* WIP on normalize/translate tools
* add requirements.txt
* [experimental] add es docs language as machine translated draft
* remove duplicate script
* Back to wider tab-stop (narrow renders not so well)
* Print error messages to stderr.
It makes it possible to redirect output to /dev/null and see only the
failed tests.
* Show an error message if we failed to find the queries dir.
* Treat 'distributed' and 'global' the same way as 'shard' in test names.
Some tests that need to run distributed queries do not use the
'shard' marker. It seems easier to support another two markers than
to rename the tests.
* CLICKHOUSE-4063: less manual html @ index.md
* CLICKHOUSE-4063: recommend markdown="1" in README.md
* CLICKHOUSE-4003: manually purge custom.css for now
* CLICKHOUSE-4064: expand <details> before any print (including to pdf)
* CLICKHOUSE-3927: rearrange interfaces/formats.md a bit
* CLICKHOUSE-3306: add few http headers
* Remove copy-paste introduced in #3392
* Hopefully better chinese fonts #3392
* get rid of tabs @ custom.css
* Apply comments and patch from #3384
* Add jdbc.md to ToC and some translation, though it still looks badly incomplete
* minor punctuation
* Add some backlinks to official website from mirrors that just blindly take markdown sources
* Do not make fonts extra light
* find . -name '*.md' -type f | xargs -I{} perl -pi -e 's//g' {}
* find . -name '*.md' -type f | xargs -I{} perl -pi -e 's/ sql/g' {}
* Remove outdated stuff from roadmap.md
* Not so light font on front page too
* Refactor Chinese formats.md to match recent changes in other languages
