7f7761e884 Improved support for "Short Date" fields 
* Separate -D (date only) and -T (date/time) format options in mdb-export and mdb-json

* New public mdb_set_shortdate_fmt() function in libmdb

* New private(ish) mdb_col_is_shortdate() function

I'm calling it "shortdate" in order to preserve the existing API.

See https://github.com/mdbtools/mdbtools/issues/12

673c7700b9 Store OLE strings on the statement object 
Also cut MDB_OLE out into its own code path. This removes the last of
the global / thread-local storage in the ODBC driver, I think.

Also fix the fact that "08001" was always returned by SQLError instead
of the actual SQL state.

9020ca9a1e Attempt to make the ODBC driver thread-safe 
I'm not sure if this is a complete solution - some of the global state
has been moved to thread-local storage. So passing an ODBC handle across
threads may have unexpected results. But at least it's not global state.

Each ODBC handle now has its own iconv_t object.

See #23

dfd41f2283 Try fixing unixODBC deadlock with -Bsymbolic-functions 
This flag compels the dynamic library to prefer its own function symbols
to those in the global symbol table. This behavior should let us
directly call SQL* functions from inside other SQL* functions without
fear of interference by the host program.

8202e38155 Don't automatically add terminators when reading data parts 
via SQLGetData for OLE fields

if the column type is OLE, then we don't add terminators
see https://docs.microsoft.com/en-us/sql/odbc/reference/syntax/sqlgetdata-function?view=sql-server-ver15
and https://www.ibm.com/support/knowledgecenter/SSEPEK_11.0.0/odbc/src/tpc/db2z_fngetdata.html

"The buffer that the rgbValue argument specifies contains nul-terminated values, unless you retrieve
binary data, or the SQL data type of the column is graphic (DBCS) and the C buffer type is SQL_C_CHAR."

e9f4c6c786 Remove GLib dependency WIP 
Add a shim implementing half-assed versions of most of the GLib
functions used by MDB Tools. If GLib is detected at compile-time,
use it, otherwise use the shim.

This work is not complete, as the option-parsing code is not yet
implemented - so most of the command-line tools crash.

e22791606f odbc: support reading OLE entries 
This adds support for reading OLE objects to the ODBC driver. The APIs
for reading OLE appear somewhat idiosyncratic, so we read the string
fully and stash it in a static variable.

Tested by reading an old Access database, with checking for memory leaks.
