CVS commit: src/common/lib/libprop

[Juan Romero Pardines <xtraeme%netbsd.org@localhost>]

Module Name:    src
Committed By:   xtraeme
Date:           Tue May  6 22:57:26 UTC 2008

Modified Files:
        src/common/lib/libprop: prop_array.c prop_dictionary.c
            prop_object_impl.h

Log Message:
prop_object_iterator_next() and prop_object_iterator_reset() were
acquiring the rwlock recursively in some paths.

Introduce _prop_rwlock_tryrdlock() and use it in these functions, so
that the rwlock is *always* acquired once, while here add some
_PROP_RWLOCK_OWNED asserts to verify.

This definitely fixes the "locking against myself" panics.
