The management protocol uses a single byte for error codes (aka command
status). In some places this value is directly copied from HCI and in
other a POSIX error number is used. This makes it impossible for
user-space to uniquily decipher the meaning of an error.

To solve this issue a new mgmt-specific set of error codes is added
along with a conversion table for HCI status values.

Using _only_ POSIX error codes in management protocol doesn't solve
this problems? We could use the bt_to_errno() function to translate
HCI errors into POSIX errors.
