Minor improvements to the get_record() cache. Part of MDL-7196
...
1) Check the cache issset() before unset() it.
2) In the set_field() function, if fieldX = 'id',
just delete such element from the cache,
else the whole table
3) Add some more unset() operations against the cache in
the delete_xxxx() dmllib functions.

- Creating one new global object to cache $db->MetaColumns() calls per request, because it's being used

dmlib: Add Oracle dirty hack cleanup to recordset_to_menu() get_field_sql() and get_fieldset_sql()
...
This covers most (all?) the gaps in data retrieval except get_recordset_sql().
To tackle get_recordset_sql, where the actual data retrieval is done within
AdoDB, we would have to to wrap around AdoDB with a subclass, but that would
be dirty, dirty, dirtier.

Introducing sql_concat() - and use it in sql_fullname()
...
sql_concat() is just a passthrough to $db->Concat() -- it doesn't
add any value, and I think the dispatching is somewhat expensive.
Just using $db->Concat() should be good enough, were it not for
consistency in our DM API.

Now all the insert_record() and update_record() calls under

Oracle DB use the oracle_dirty_hack() function to transform
empty strings into something different ' ' in order to avoid
the problems with the empty=NULL stupid norm of Oracle.
With this change, Oracle installation works completely.
Now we need to implement everywhere the opposite hack: transforming
all those ' ' (1 whitespace) back to the '' (empty string). Working
on it now.
