add an endpoint command for "bridges" that use addresses as endpoints.

this can be used to add static entries on interfaces like vxlan(4).

Remove switch(4) specific bits from ifconfig.

Merge switch_status() into bridge_status()

This is to reduce duplicate code and prepare for bridge_status() to cover
all bridge like interfaces: bridge(4), switch(4) and tpmr(4).

Fix ifconfig(8) compiler warnings regarding variable "name" reuse.
Call the global variable with the name of the interface "ifname".
Do not pass it around, just use it globally. Do not use "ifname"
for anything else.

Fix some compiler warings in ifconfig(8). Move all prototypes and
variables used in multiple .c files into common ifconfig.h. Basically
this renames brconfig.h to ifconfig.h and also uses it for sff.c.
Fix missing prototypes. Global variable name s is bad as it shadows
local variables. Call it sock and use it everywhere.
