The network device driver can specify what kind of functionality
it supports. Currently there exists one flag that can be used
in ethernet devices that tells that ARP should be enabled.

This just renames the existing net_buf helper APIs to corresponding
net_buf_simple APIs and then defines the old net_buf API names as
macros mapping to the new net_buf_simple helpers.

The object has the same layout as the last fields of the existing
net_buf. To maintain backwards compatibility net_buf receives a union
so that the old data, len and size members can be accessed as before,
however they are located in the same memory as the actual
net_buf_simple members.

Use IOAPIC_EDGE instead of IOAPIC_LEVEL to fix missing interrupts.
During tests it was found that using IOAPIC_LEVEL interrupts for UART at
some points are lost.
