Sergei Golubchik 2fcd8c1252 MDEV-13173 An RLIKE that previously worked on 10.0 now returns "Got error 'pcre_exec: recursion limit of 100 exceeded' from regexp" ...

1. use Regexp_processor_pcre::set_recursion_limit() to set the
   recursion limit depending on the current available stack size
2. make pcre stack frame to be estimated no less than 500 bytes.
   sometimes pcre estimates it too low, even though the manual
   says 500+16 bytes (it was estimated only 188 for me, actual
   frame size was 512).
3. do it for embedded too
