ANALYZE and ANALYZE FORMAT=JSON structures are changed in the way that they
show additional information when rowid filter is used:
- r_selectivity_pct - the observed filter selectivity
- r_buffer_size - the size of the rowid filter container buffer
- r_filling_time_ms - how long it took to fill rowid filter container
New class Rowid_filter_tracker was added. This class is needed to collect data
about how rowid filter is executed.
[0-9]*[.]?[0-9]* wasn't a sufficient regex to cover the
%lg used in Json_writer::add_double. Exponent formats
where missed.
Here we normalize all the replace_regex expressions for
ANALYZE FORMAT=JSON into one include file.
