2.3.5
* Add configure option --enable-setlibversion set mark the libs with VERS_3.52
Linux only, so any driver built with the libs will work with closed source
DM's
* Add persistent storage of isql command line history if readline() is used (thanks Axel)
* Rename some local mutex functions to avoid name clashes
* Assorted fixes (Thanks Markus * 2)
* Fix regression in ini caching
* Make SQLDrivers look in user as well as system odbcinst.ini for driver attributes
* If in use, clear the ini cache when a write is done via SQLWritePrivateProfileString() so
the new value is read
* Fix problem with pooling if the environment was released by the application
* Add check for SQL_COLUMN_COUNT in SQLColAttribute
* isql would not display long error messages. Fixed now.

has not been called

* SQLBindParameter does not ignore BufferLength for DAE parameters
* SQLBindParameter does not ignore BufferLength for fixed-length parameters
* SQLBindParameter returns "Invalid application buffer type" instead of " Program type out of range"
* SQLCancel with 01S05 returned from driver should result in SQL_SUCCESS, not SQL_SUCCESS_WITH_INFO
