Use pkb_available() rather than pkb_len() (which will always return 0
on a freshly allocated buffer).

udp_send() should assume that the buffer has already been allocated.

Zero the DHCP packet buffer *before* creating the options structures

structure, and populating it with options.  This should allow us to
use the same basic options list for both DHCPDISCOVER and DHCPREQUEST,
plus making it much easier to set the non-constant parameters
(e.g. requested IP address) in request packets.

Move some static inlines that are likely to be used frequently into
dhcpopts.c as normal functions, to save space.

derived is a 16-bit big-endian field, but htype is only 8 bits wide.

is a DHCP option" data structures.

We need this code in order to be able to return a DHCP packet to a PXE NBP
which reflects options from our multiple sources (e.g. NVS and DHCP
server).  This is expensive, but necessary.  Having paid this cost, we may
as well try to use the same code to generate our DHCP request packets,
since the process is similar.

- value of n passed to wgetnstr should now be equivalent to output from strlen (i.e. length excluding NUL-terminating character)

- reimplemented cleaner wgetnstr
- fixed wdelch for use with _wcursback

- added mucurses_test.c build targets
