Merge branch 'master' into topic/constructor_rewrite

Add some extra code to enforce the assumption that any bind type constant
is accessible in _dbi_attrs_for_bind, or in other words that all necessary
DBDs are already loaded (concept originally introduced in ad7c50fc)

Without this the combination of 9930caaf7e (do not recalculate bind attrs
on dbh_do retry) and a2f228547 (do not wrap iterators in dbh_do) can result
in _dbi_attrs_for_bind being called before DBI/DBD::* has been loaded at all

  Revision history for DBIx::Class
  
+     * Fixes
++        - Fix _dbi_attrs_for_bind() being called befor DBI has been loaded
++          (regression in 0.08210)
+         - Fix update/delete operations on resultsets *joining* the updated
+           table failing on MySQL. Resolves oversights in the fixes for
+           RT#81378 and RT#81897
+         - Stop Sybase ASE storage from generating invalid SQL in subselects
+           when a limit without offset is encountered
+ 
+ 0.08210 2013-04-04 15:30 (UTC)
+     * New Features / Changes
+         - Officially deprecate the 'cols' and 'include_columns' resultset
+           attributes
+         - Remove ::Storage::DBI::sth() deprecated in 0.08191
+ 
+     * Fixes
+         - Work around a *critical* bug with potential for data loss in
+           DBD::SQLite - RT#79576
+         - Audit and correct potential bugs associated with braindead reuse
+           of $1 on unsuccessful matches
+         - Fix incorrect warning/exception originator reported by carp*() and
+           throw_exception()
+ 
 +0.08242-TRIAL (EXPERIMENTAL BETA RELEASE) 2013-03-10 14:44 (UTC)
 +    * New Features / Changes
 +        - Prefetch with limit on right-side ordered resultsets now works
 +          correctly (via aggregated grouping)
 +        - Changing the result_class of a ResultSet in progress is now
 +          explicitly forbidden. The behavior was undefined before, and
 +          would result in wildly differing outcomes depending on $rs
 +          attributes.
 +        - Scale back validation of the 'as' attribute - in the field
 +          there are legitimate-ish uses of a inflating into an apparently
 +          invalid relationship graph
 +        - Warn in case of iterative collapse being upgraded to an eager
 +          cursor slurp
 +        - No longer order the insides of a complex prefetch subquery,
 +          unless required to satisfy a limit
 +
 +    * Fixes
 +        - Properly consider unselected order_by criteria during complex
 +          subqueried prefetch
 +        - Properly support "MySQL-style" left-side group_by with prefetch
 +        - Fix $grouped_rs->get_column($col)->func($func) producing incorrect
 +          SQL (RT#81127)
 +
  0.08209 2013-03-01 12:56 (UTC)
      * New Features / Changes
          - Debugging aid - warn on invalid result objects created by what
