* Missing check: SQLAllocHandle() for the environment wasn't checked in
pdo_odbc_handle_factory(). Add a check similar to the other ones for
SQLAllocHandle().
* Inconsistent check: one of the SQLAllocHandle() calls wasn't checked
for SQL_SUCCESS_WITH_INFO. However, looking at the other uses and the
documentation we should probably check this as well.
Furthermore, since there was a mix of "SQLAllocHandle: reason" and
"SQLAllocHandle (reason)" in the error reporting, I made them
consistently use the first option as that seems to be the most used for
error reporting in this file.
Closes GH-10740.
