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.

The kernel needs to know whether it should connect to a device over
BR/EDR or over LE. This is particularly important in the future when
dual-mode device may be connectable also over LE. It is also important
if/when we decide to move the LE advertisement cache from the kernel
into user-space. Adding the type to the mgmt command also ensures
conformance with the latest mgmt API spec.

Add management interface events for blocking/unblocking a device.
Sender of the block device command gets cmd complete and other
mgmt sockets get the event. Event is also sent to mgmt sockets when
blocking is done with ioctl, e.g when blocking a device with
hciconfig. This makes it possible for bluetoothd to track status
of blocked devices when a third party block or unblocks a device.

Event sending is handled in mgmt_device_blocked function which gets
called from hci_blacklist_add in hci_core.c. A pending command is
added in mgmt_block_device, so that it can found when sending the
event - the event is not sent to the socket from which the pending
command came. Locks were moved out from hci_core.c to hci_sock.c
and mgmt.c, because locking is needed also for mgmt_pending_add in
mgmt.c.
