Fixes fdo#36594 Syntax error in SQL on "--" comment (and "//" and "/**/")

The SQL parser implementation does not handle comments.
Temporarily remove "-- ..." and "// ..." end-of-line comments and "/* ... */"
inline comments of a query and append comments after recomposition of the
query.

NOTE: The original comment positions are not preserved, all comments are
      appended to the query!

Based on the original patch further development was done for inline comments
and preserving comments' line order.
