Rename the library to wsap_vtcore

ncurses installs <term.h> and defines struct term. In a file that
includes both headers, an ncurses TERMINAL * and this library's terminal
are silently the same type. The name wsap_vtcore avoids the clash.

The public header is now <wsap_vtcore/wsap_vtcore.h>. Every global
symbol uses the wsap_vtcore_ prefix, every macro uses WSAP_VTCORE_, and
the shared library is libwsap_vtcore.so.0. The default terminal name is
now "wsap_vtcore". The ISA override variable is WSAP_VTCORE_ISA.

No other behavior changes. The amalgamation writes wsap_vtcore.c and
wsap_vtcore.h.
