e789c3bea1 iplink: implement support for selecting a master interface 
Attaching an interface to a VRF is done by setting the interface's
master. Besides VRF, this can also be used for bridges.

0f296a3a56 libiproute: rename invarg(a,b) to invarg_1_to_2(a,b) 
invarg(a,b) - "invalid argument", but how a and b enter the message?

invarg_1_to_2(a,b) is somewhat easier to read: "invalid argument 'a' to 'b'"

Audit of usage revealed a number of bad uses, with too long messages.

ec2bef11a7 iplink: comment out include <net/if_packet.h> 
iplink.c includes net/if_packet.h, which (on GLIBC)
only defines struct sockaddr_pkt. this struct is not
used anywhere in the code, and removing the #include
makes compilation succeed with musl libc.
