ed9aa89269 wget: implement --post-file
Add the --post-file option to send form data from a file.  As with
--post-data it's up to the user to ensure that the data is encoded
as appropriate:  all wget does is stuff the provided data into
the request.

The --post-data and --post-file options are mutually exclusive and
only one instance of either may be given.

Additionally:

- update the usage message to include missing details of the --post-data
  and --header options;

- free POST data if FEATURE_CLEAN_UP is enabled.

BusyBox on Termux can't use ports less than 1024 it's patched to change default port for httpd to 8080 and telnetd to 8023.

To avoid such patches we can make port configurable.

274ce6cce1 udhcpc: revert deprecation message for -V
"-x vendor:VENDOR" will not be a trivial replacement of it:

(1) by default, we do send a vendor string ("udhcp BB_VER"),
will need code to preserve the default.

(2) -V '' currently disables vendor string. -x vendor:''
would not easily achieve that: it adds no option at all
(string options can't be empty), and default (1) would trigger.
To avoid that, we will need yet another hack to detect
-x vendor:'' and interpret that as "no vendor string at all".

IOW: removing -V is likely to increase code size, not decrease.

5a3d3b8055 udhcpd: don't hardcode treating .0 and .255 specially
Even following current Internet standards, it can be perfectly
legitimate to issue IPv4 addresses that end in .0 or .255 via DHCP --
this can happen whenever the network is larger than /8.  For example,
10.3.4.0 and 10.3.4.255 are legitimate host addresses in 10/8 or 10.3/16.
(We also want to be able to issue .0 addresses in smaller networks
following our proposed kernel patch and standards changes.)

This behavior is already fully controllable by the user, simply by
setting start_ip and end_ip correctly.  Users who don't want to issue
.0 or .255 should set start_ip greater than .0 or end_ip less than .255
and udhcpd will already respect these bounds.  (This is also the case
for other DHCP servers -- the recommended example configurations will
default to a lower bound starting with .1 or some other value, which is
typically appropriate, but the user is still allowed to change this to
.0 -- or to a range that overlaps a .0 or .255 address -- if so desired.)
