Fixes:
zebra/zebra_netns_notify.c: In function 'zebra_ns_ready_read':
zebra/zebra_netns_notify.c:265:40: error: implicit declaration of function 'basename' [-Wimplicit-function-declaration]
265 | if (strmatch(VRF_DEFAULT_NAME, basename(netnspath))) {
| ^~~~~~~~
Fixed by including libgen.h, then since basename may modify its
parameter, allocate a copy on the stack, using strdupa, and pass the
temporary string to basename.
According to the man page for basename:
With glibc, one gets the POSIX version of basename() when
<libgen.h> is included, and the GNU version otherwise.
The POSIX version of basename may modify the contents of path,
so we should to pass a copy when calling this function.
