[OSS-Tools] [dt-utils] Release 2019.01.0

[Roland Hieber]

Hi,

I've just released version 2019.01.0 of dt-utils [1]. Highlight of this
release is the harmonization of the barebox-state implementation with
upstream barebox, thanks to Ulrich Ölmann for working on this!

all contributors!

Changes:
* libdt: fix leaks of memory returned by read_file() calls
* libdt: xzalloc: die on failure, like the similar-named kernel function
* libdt: add of_property_write_string() as a convenience function to set
  a property to a string
* libdt: add dev_set_name() as a convenience function to set a device's
  name
* state: harmonize our implementation with upstream barebox:
  - Fixes:
    . backend_bucket_circular: fix the case when write size is not a
      power of 2
    . backend_bucket_circular: fix length check when reading old state
      format
    . backend_bucket_circular: fix two memory leaks
    . backend_storage: don't refresh the storage needlessly
    . fix error return value when state_new_from_node() cannot resolve a
      phandle
    . fix use-after-free in state_backend_format_dtb_pack()
    . make finding the backend node more robust by using its
      reproducible name
    . remove checks for xzalloc() returning NULL, which cannot happen
    . do not complain about missing backend-storage-type, which is
      irrelevant for mtd devices
  - Potentially breaking changes:
    . make pointing to the backend using a phandle the only supported
      method
    . state nodes without an alias in the /aliases/ node now lead to an
      error. barebox already creates a missing alias in the fixupped
      device tree automatically since v2017.06.0.
    . refuse to set the read-only 'dirty' state variable
    . remove unused arguments from state_new_from_node()
  - New features:
    . add new 'init_from_defaults' state variable to allow detection
      whether a state has been initialized from default values, i.e.
      state_load() failed.
    . add an internal variable to protect existing data in a state
      bucket and make updates of the
      state implementation more robust
    . add new function state_read_mac() to read a MAC address from state
    . notify when the old state format is detected (this was previously
      a debugging message)
    . provide an error message when an error occurs in
      state_convert_node_variable()
    . add more debugging messages
  - port several changes to barebox's fixup functions, but since device
    trees are already fixupped at boot time, this code is never used by
    dt-utils
  - some further minor refactoring as well fixing some typos and
    documentation comments
