Change sp_256to512z_mont_{mul,sqr}_8 to not require/zero upper 256 bits.
There is only one place where we actually used that (and that's why there
used to be zeroing memset of top half!). Fix up that place.
As a bonus, 256x256->512 multiply no longer needs to care for
"r overlaps a or b" case.
This shrinks sp_point structure as well, not just temporaries.

It worked by chance because the only caller passed both parameters
as two pointers to the same array.
My fault (I made this error when converting from 26-bit code).

Previous change made it obvious that we zero out already-zeroed high bits

range_start was staying -1, and comparison meant to detect
"is it the first sendfile that failed, or not the first?"
was making incorrect decision. The result: nothing is sent.

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.
https://github.com/termux/termux-packages/blob/master/packages/busybox/0011-networking-telnetd-default-port.patch
https://github.com/termux/termux-packages/blob/master/packages/busybox/0010-networking-httpd-default-port.patch
To avoid such patches we can make port configurable.
