Before this patch, replxx history_next/history_previous (which were
mapped to UP/DOWN) navigates through history lines first (in multi-line
mode, and after through history.
But it is not convenient, since in case of query contains lots of line
it can take awhile.
So now, after this update, replxx will change the meaning of
history_next/history_previous (which will be binded to M-UP/M-DOWN),
those actions will always navigates through history lines.
And new actions, line_next/line_previous (binded to UP/DOWN) will
navigate through lines of current item first, and when it reaches
begin/end it will go the previous/next history item.
Also note, that ClickHouse rebind of C-P/C-N is fine, since it is binded to
history_next/history_previous, and this is desired (like in readline).
Follow-up for: #30143 (cc: @amosbird)
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
This should fix the following SIGSEGV, that was found on CI [1]:
