MDB_DEPRECATED redefined, Constructor MACRO, generate_table_schema changed to not static, date_fmt to ISODate

__attribute__ does not exist in Visual Studio. Therefore replaced wherever it appeared with a macro:
Redefines MDB_DEPRECATED to support Visual Studio
Define a Constructor MACRO so that __attribute__((constructor/destructor)) behavior is achieved in Visual Studio.

Just using generate_table_schema through mdb_print_schema deletes the purpose of a very good tool. generate_table_schemas is a rewrite of generate_table_schema but sends the data to a char* instead of FILE*. There is NO fmemopen() or similar in Visual Studio, so there is NO way to access memory through a FILE* except for first writing to the disk and then reading from the disk in memory.

I cannot suggest how to handle the case when td == 0 for the dates. The databases I work with often have just 00:00:00 in the DateTime column which is not consistent with the rest of the column either, but I have to deal with it somehow.

Leaving void* where char* is needed as a function parameter returns a compilation error in Visual Studio.
