The commit c4d8d937d5 added null byte for
obstack_vprintf and thus to obstack_printf. I probably lost my marbles
but the same test I run previously now won't append null byte at the end
and this "fix" now causes regressions in code using obstack.
For the reference this is the testing code:
#define _GNU_SOURCE
#include <obstack.h>
#include <stdarg.h>
#include <stdio.h>
#include <stdlib.h>
#define obstack_chunk_alloc malloc
#define obstack_chunk_free free
static void print(struct obstack *obs, const char *fmt, ...) {
va_list arg;
va_start(arg, fmt);
obstack_vprintf(obs, fmt, arg);
va_end(arg);
}
int main(int argc, char *argv[]) {
struct obstack obs;
obstack_init(&obs);
obstack_printf(&obs, "this %s", "text ");
obstack_printf(&obs, "is appended");
print(&obs, " as well as %s", "vprintf text");
obstack_1grow(&obs, '\0');
printf("%s\n", (char *)obstack_finish(&obs));
obstack_free(&obs, NULL);
return 0;
}

The new API is defined by GNU and implemented in other LibCs, such as
Musl.
This also modifies API of obstack_blank_fast and obstack_1grow_fast.
These are defined as returning void and thus return value here is
incompatibility with other implementations.
In file "nuttx/libs/libc/modlib/modlib_bind.c", line656 not check return value of lib_malloc(), and line661 not free dyn.
