Converts the list and the core manipulating with it to be the same as uc_list.
+uses two functions for adding/removing mc address (normal and "global"
variant) instead of a function parameter.
+removes dev_mcast.c completely.
+exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
manipulation with lists on a sandbox (used in bonding and 80211 drivers)

The mac is expected to auto-inflate the Maximum Frame size for VLAN
tagged frames. It however does not work with jumbo frames.
Work around the bug adding 4 to the Maximum Frame for MTUs
greater than 1536.

The driver currently ignores the local or remote link faults
raised at the mac layer. This patch fixes it.
Our mac however only advertizes link events, so wait for the
phy to stabilize the link, then enable mac link events interrupts.

Update the heurstics workaround unlocking a hung mac:
- reduce Tx mac toggling by enabling Tx drain before resetting the mac
- Take Tx (lack of) activity in account only
- Update the monitoring counter range to 64 bits

periodic MAC state check, and triggers a recovery if hung.
