Testing Done: Tested ifupdown2 sanity + multiple iface sections for an
interface
- This patch fixes a few shortcomings in the multiple iface sections
for same interface (partly because i was only covering
backward compatibility cases earlier)
- Since this is a very common configuration pattern, this patch cleans
it up
- also restructures some code
- main change is:
before:
for iface in ifaces:
for op in ops:
run op on iface
after:
for op in ops:
for iface in ifaces:
run op on iface

Testing Done: Tested interfaces file with duplicate entries
Old ifupdown allowed multiple stanza's for the same interface.
To support older files ifupdown2 will continue to support duplicate interfaces.
However this check will warn on interfaces with same config more than
once. The check is done at a higher level during parsing and hence only
does a string compare of the iface section.

Testing Done: Tested ifup, ifdown in bond bridge setup
Also, implicitly pick up the upperifaces (even when user has not
specified --with-depends) for logical interfaces.
This is because when a logical interface goes down/deleted, kernel
impilicity deletes its upperifaces. so its better to implicitly bring
up upperifaces.

Testing Done: Tested ifup/ifdown
Before this patch, `ifup --with-depends <iface>` only brought up
lowerdevices. Because those were enough for iface to function.
And if ifaces above it (upperdevices) needed fixing, user could just
execute `ifup --with-depends <ifaceupper>`.
But in a recent, bond under a bridge bug in 2.0, got me thinking that
its probably better to up the upperdevices which might be impacted as
well. and this patch does just that.
The patch includes changes to make ifupdown generate dependency
information for all interfaces even if the user requested to operate
on a single interface. This is to get a full view of the interfaces file.
This might add some overhead. Should not change anything during boot.
Still looking at ways to optimize.

This also fixes a bug with address handling:
- If the user changed a primary address, flush all the addresses and
re-add them. Previously, if user added a new primary address, it would
ust get appended to the end of the address list as a secondary address.
