* Purge most special cases for building ODBC with specific drivers
PDO_ODBC doesn't do this, and most of these drivers are not in use with
PHP, at least like this. Chances are these expose an ODBC driver you can
use with a normal driver manager like unixODBC or iODBC. If not, it can
be specified as a custom driver, though it does not include any
workarounds.
There might be some redundant definitions now as a result.
IBM Db2 is kept as a special case due to it also being in PDO_ODBC,
though I wonder how good of an idea this is.
See GH-15630
* Remove never used include
This would only be used on 68k classic Mac OS. Did PHP ever run there?
* Fold HAVE_SQL_EXTENDED_FETCH
All supported driver managers can do extended fetches.
* Ope, accidentally deleted this in a refactor
* All driver managers support SQLDataSources now too
So we don't need the define?
* Remove undef CHAR
There's no justification behind as to why this should be.
* Don't special case SQL_TIMESTAMP
The default handling for turning into SQL_C_CHAR is fine, and the
special case for Adabas is no longer needed.
* Assume fetch_hash is always possible
The driver managers and even Db2 support this.
This would also allow simplifying the fetch code to merge fetch_into and
fetch_array into a single implementation perhaps.
* Update UPGRADING for driver specific removal
* Update NEWS for driver specific removal
