Adding new cases to the pxe parser code of having conffile file without

Update the parser test code/cases as per new prototyping of parse()
function which doesn't require buf and len to be passed from the caller,
instead reading the configuration data either embedded or from file to
a parser's known conffile.

Add a new function parser_request_url() to read the data from
configuration files present remotely. We deprecate
iterate_parser_files() and download_config() functions along with the
'filenames' and 'method' members of the 'parser' structure so that
individual parsers would now require to request the configuration files
data from the parser code and doesn't necessarily export the list of
configuration files.
Add the support to handle incoming DHCP event, done by passing all the
relevant environment variables of the udhcpc to the discover code.
Also, update the pxe parser code to populate the list of configuration
file names as per PXELINUX convention of fallback names using mac and ip
addresses of the booting machine.

We're currently seeing empty log files from the discover server. Rather
than only flishing if the server was compiled with debugging enabled,
always perform the fflush.

Currently, we drop any netlink data beyond our 4096-byte buffer. This
means that we can only parse a limited number of network interfaces.
This change uses recvmsg with MSG_PEEK to determine the size of an
incoming netlink message before doing the actual recvmsg. This way, we
can realloc our buffer to suit.

Currently, if we see an error when writing to a client, we free the
client immediately. This means that any pending reads will be discarded.
Additionally, if a client disconnects before we have finished the writes in
discover_server_process_connection, we won't register the waiter to read
from the socket.
Instead of freeing the client on write failure, this change sets a flag
(se we don't continue to write), and we rely on the read EOF to free the
client. This means we don't drop incoming messages.

Because terminals will send escape-sequences starting with escape,
ncurses will pause after receiving a signle escape, to detect
these sequences. This introduces a 1-second delay when exiting the
petitboot UI.
Instead, use 'x'.

Currently, when creating new menu entries, we create an empty item, add
it to the menu, then run the boot editor. This means that cancelling the
edit will leave an empty item in the menu.
This change defers the creation until the boot editor is done. To do
this, we modify the on_open callback to take a menu rather than an item,
and pass NULL boot data to the editor.
