[OpenWrt-Devel] [PATCH] libubox: use const *attr in getters

[Peter Stadler]

Change the signature of the following get-functions to accept
the `struct blob_attr *attr` as `const`:
  - blobmsg_get_u8
  - blobmsg_get_bool
  - blobmsg_get_u16
  - blobmsg_get_u32
  - blobmsg_get_u64
  - blobmsg_get_double
  - blobmsg_get_string
This allows to get the values instead of calling blobmsg_data.
