Some curses implementations have tparm(char *) (BSD and older ncurses), some
have tparm(const char *).
The older POSIX specification had: tparm(char *):
https://pubs.opengroup.org/onlinepubs/7908799/xcurses/term.h.html
Just cast it to char *. The terminfo variables are defined elsewhere so it
should be safe.
Also remove an unnecesary cast in minicurses.
Hopefully this satisfies all curses variants and versions now.

Older POSIX standards also defined it as a char * parameter (not const char *)
for tparm().

This makes atleast feeds with simple ASCII work.

This fixes a compile error tested with HaikuOS 32-bit (gcc2h, based on gcc
2.95).
It also suppresses a false-positive warning of an unused forkexec function in
cppcheck.

This replaces the current J and K keybind, which was rarely useful.
Thanks to IanJ for the suggestion and feedback!

When a new URL file is used with no URL entries then NULL is passed to qsort()
and bsearch(). This is reported by clang UBsan as undefined behaviour
(debatable), but no issue in practise with many implementations. Fix it anyway.
To reproduce with clang UBsan:
Compile with clang or gcc with CFLAGS and LDFLAGS -fsanitize=undefined
touch /tmp/urls # new file which should be empty.
SFEED_URL_FILE=/tmp/urls sfeed_curses 2>/tmp/log
^D
q
cat /tmp/log

Import sfeed_curses into sfeed.
The files are based of the commit 8e151ce48b503ad0ff0e24cb1be3bc93d6fbd895
