* dbus/dbus-marshal-validate.h: Added a new validation
error code DBUS_VALIDITY_UNKNOWN_OOM_ERROR = -4 for
out of memory errors when validating signitures
* dbus/dbus-marshal-header.c: use DBUS_VALIDITY_UNKNOWN_OOM_ERROR
in places where we previously used DBUS_VALID and a FALSE return
value to indicate OOM
* dbus/dbus-marshal-validate.c (_dbus_validate_signature_with_reason):
Use a stack to track the number of elements inside containers. The
stack values are then used to validate that dict entries have only two
elements within them.
(validate_body_helper): check the reason for failure when validating
varients
* dbus/dbus-message.c (load_message): use
DBUS_VALIDITY_UNKNOWN_OOM_ERROR in places where we previously used
DBUS_VALID and a FALSE return value to indicate OOM
* doc/TODO: remove "- validate dict entry number of fields" as this
patch fixes it
