Try to fix some pthread problems detected on NetBSD 4.0_STABLE

(and may be later).

* When connecting a SQL server, isql crashed.

	isql: Error detected by libpthread: Unlocking unlocked mutex.

* Setting "Threding = 0" in odbcinst.ini, isql crashed when closing
  connection to a SQL server.

	isql: Error detected by libpthread: Destroying locked mutex.

I've checked mutex handling and created patches.

Bump PKGREVISION.
