PHP Bug Type:     ODBC related
Bug description:  ODBC fixes & new feature

Things I have attempted to fix and are illustrated by the enclosed diff (if
I were more expert I'd call it a patch but I've done virtually no patch
files and so make no such claim):

1. odbc_next_result calls SQLMoreResults but does not properly report an
error resturned from the call (anything but SQL_SUCCESS is treated like
SQL_NO_MORE_DATA).  This defeats attempts to detect errors in mid-batch.

2. PHP documentation claims that odbc_error and odbc_errormsg are blank if
no error has occured, but in reality they are uninitialized until an error
occurs.

3. I also blank odbc_error and odbc_errormsg in odbc_exec so that (among
other things) upon a FALSE return from odbc_next_result, an error can be
distinguished from normal no-more-data.

4. Microsoft documentation claims that callers to SQLDriverConnect should
provide at least a 1024 byte buffer.

5. I added a function odbc_get_handle which yeilds the underlying HDBC as
a long, for a given $dbid resource.
