We are calculating the size of the array, and need to pass the size of
each element, not the size of a pointer to an element. Although this
happens to be the same in many cases, this is not a portable assumption.

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.

The test in test/strmode.c can fail to compile depending on the
optimization flags used.
The constants that are used in this file (S_IFREG etc.) come from the
<sys/stat.h> include file. It seems gcc ignores this error if one
compiles with "-O2" (default), but if one uses no optimization it fails.
Add the missing include and it works all the time.

When running tests in parallel (e.g. using `make -j4 check`), the header
tests currently fail due to headers-overlay.sh and headers-system.sh
both generating headers-gen.c simultaneously, resulting in garbled
output. Fix this by using separate C files for the tests.

Reuse the getentropy code for Linux on the Hurd, which has fallbacks
for when the better interfaces are not present. And remove all the code
that is not supported currently on the Hurd. Ideally the Hurd should
get an equivalent interfaces that does not suffer from the same
problems as /dev/urandom.
The Unix hook should work for most Unix-like systems, move glibc
specific code there and a FreeBSd specific comment, and remove the rest.
Also change the code to always fallback to use the generic Unix code.
This should cover GNU/Hurd and GNU/kFreeBSD among others.
Actually use the local private SHA512 header instead of relying on the
OpenSSL one for no good reason. Add definition for expected macro
SHA512_DIGEST_LENGTH.
Rework arc4random_stir() and arc4random_addrandom() code over the new
internal API, and documentation in the man page. Adapt the code to the
local build system.

The funtools project ships a man page with the same, name. And although
it mith probably make more sense to rename the man page there, as BSD
systems will certainly not do so, this is the easiest and fastest way
to avoid a file conflict.
The fparseln() function had the NetBSD uppercase macros stubbed out,
so replace them with the actual stdio ones. The fgetln() function was
missing any locking at all.
Although the current implementation in libbsd is probably one of the
safest ones around, it still poses some problems when used with many
file streams. This function has now a replacement, that is both more
standard and portable. Ask users to switch to getline(3) instead.
Some 64-bit platforms (e.g. Windows 64) have a 32-bit long. So, shifting
1UL 32-bits to the left causes an overflow. This replaces the constant
1UL with (size_t)1 so that we get the correct constant size for the
platform.
Import from OpenBSD.
