MDEV-15698: Spider ignores syntax errors in connection string in COMMENT field 

When a comma separator is missing between COMMENT fields, Spider ignores the
parameter values that are beyond the last expected parameter value.  There are
also some error messages that Spider does generate on COMMENT fields that are
incorrectly formed.

I have introduced additional infrastructure in Spider to fix these problems.
