Ensure server identifier matches the offer server identifier when
looking for ACKs or NAKs.
This protects against rogue DHCP servers NAKing requests the shouldn't.

RFC 2131 gives two examples of padding in section 4.1. For both the
examples, the 'end' option preceeds the padding with the 'pad' option.
These examples relate to overloading pre-defined fields for options,
not padding the packet for a minimal size.
Older versions of the U-Boot firmware support DHCP, but do not expect
the 'pad' option. The firmware logs the following warning for each
occurence:
*** Unhandled DHCP Option in OFFER/ACK: 0
This warning disappears when the 'end' option preceeds the 'pad'
option.

For any users to write their own Discover or Request methods, they need
access to the ifaceHWAddr and serverAddr.

When parsing a route option with a mask size >32, there would be a panic
at option_routes.go:47 as user-supplied data is used without
verification for a slice bound, causing a read of masksize/8, whic is
possibly >4 bytes. Instead reject the invalid route

When there was a 0-length generic option, it would be omitted.
Rapid commit (option 80) is a 0-length option with a length tag.
There could also be 0-length options in the vendor extensions, and the
RFC states that they should be written out:
> Any options defined subsequent to this document should contain a
> length octet even if the length is fixed or zero.

There is a special case for when ClientHwAddr is empty, which seems to
only apply when creating a packet with New(), which defaults to
HWType==Ethernet but doesn't assign the ClientHwAddr field.
All the other New*() constructors assign a hardware address and don't
use this codepath
Remove this special case and instead make New() generate an
almost-correct packet in the first place, so that ToBytes() can stay
more generic

When BootFileName is longer than 128 bytes or ServerHostName is longer
than 64 bytes, trying to null-terminate the strings when writing out the
packet causes a panic.
Since the ToBytes() function cannot return errors, silently truncate the
string instead (we do the same with ClientHWAddr if it is longer than 16
bytes for example)

Those 2 tests did the exact same thing: check that an invalid packet
raises an error when parsed. Merge them into the same test, so that we
can easily add more test cases to the list
