Use a local variable instead of casting the address of a SQLSMALLINT
to a (size_t *). sizeof(SQLSMALLINT) < sizeof(size_t) so gcc is
rightfully giving the following errors when building on Fedora 34:
/usr/include/sqlucode.h: In function 'SQLErrorW':
odbc.c:130:20: error: array subscript 'size_t[0]' is partly outside array bounds of 'SQLSMALLINT[1]' [-Werror=array-bounds]

* Add [brackets] around mdb-query table names
* Allow column and table names to be in brackets
Column and table names can have whitespace in them. The traditional way
to indicate that is with bracket characters, like so:
```sql
SELECT [column name] FROM [table name]
```
This change updates the parser to allow bracket format -- similar to
double-quoted format -- in all NAME contexts, i.e., column names, table
names, and database names.

`GFunc` is `void (gpointer, gpointer)` and `GHFunc` is `void (gpointer, gpointer, gpointer)`,
so the respective callback functions should have the same signature.
dont access pages in mdb_fetch_row when pdata is not initialized.
Happens when a client, e.g. pyodbc, queries for an unsupported type,
e.g. SQL_WVARCHAR, temp_table is empty and further access to it will crash.

Per #260 I am assuming that the internal version 6 refers to files
created with Access 2019. I can't find any documentation on this format,
so I am calling it ACE17. Testing welcome.
