terminfo: test strlcpy result against space free, not string length

riastradh@ yep, looks good.

Clean up some compile warnings.

- if we are freeing cur_term, set it to NULL.
- preserve and free "last" properly.

$ cat foo.c
#include <stdio.h>
#include <termcap.h>

int
main(void)
{
tgetent(NULL, "dumb");
tgetent(NULL, "network");
tgetflag("so");
return 0;
}
$ cc foo.c -lterminfo
$ MALLOC_OPTIONS=J ./a.out
Boom.

PR/50092: Fix memory leak.

branches: 1.10.4; 1.10.8;
Use an empty string, not a null pointer for nullname.

Whitespace

branches: 1.8.2; 1.8.8;
There is no standard way of getting a list of aliases for the
terminal. However, some applications such as telnet want to know this.
ncurses dumps the terminfo header into an undefined variable ttytype
and these applications then parse it to work out the aliases.
We should do the same for now, until a standard mechanism for getting
the information is available or the need for it goes away.

Move longname(3) from curses to terminfo, pre-cursor to fix PR/43386.

Remove _ti_freeterm as consumers should just use del_curterm.

Add termname(3) as defined by POSIX.

libterminfo can now compile a single terminfo description which allows
$TERMINFO to be a terminfo description as well as a file reference.

This enables the user to modify the terminfo description on read-only
media.

Remove silly debug.

Embed ansi, dumb, vt100, vt220 and wsvt25 compiled terminal descriptions
into libterminfo.
Constify some foo.

Import my terminfo implementation.
This uses the ncurses terminal definitions.

OK: core@, jdc@
