build: Clarify link-time warnings
Mention the involved function instead of stating an implicit "this
function". Mention libbsd when proposing using an alternative libmd
to make the context clear.

Require a semicolon for libbsd_link_warning() macro
Remove the semicolon in the macro definition to force adding one on the
call sites, to make the code look like an actual function.

Fix heap buffer overflow in fgetwln()
In the function fgetwln() there's a 4 byte heap overflow.
There is a while loop that has this check to see whether there's still
enough space in the buffer:
if (!fb->len || wused > fb->len) {
If this is true more memory gets allocated. However this test won't be
true if wused == fb->len, but at that point wused already points out
of the buffer. Some lines later there's a write to the buffer:
fb->wbuf[wused++] = wc;
This bug was found with the help of address sanitizer.
