Switch md5 compatibility logic back to direct linking
When using the recent dlsym() based wrapper, we are not requiring any
symbol from libmd, as we resolve those dynamically at run-time. We were
ending up linking against libmd because in another part of the code we
require (depending on the architecture) the SHA512 functions for the
getentropy() local implementation. But that function might be provided
by the system libc on some systems, which means we end up not linking
against libmd at all.
To solve this we go back to the previous simpler solution of linking
directly, which had the main drawback of then making programs fail to
link when not specifying -lmd (on platforms that need it). And then
switch the .so link point from a symlink to a linker script, so that we
can inject the -lmd library as-needed. This is similar to what glibc is
doing.

To be able to rework the md5 deprecation logic, we need to detangle when

otherwise provided by libc, or when we require SHA functions for the
internal getentropy() implementation.

This is a glibc-specific symbol that has no public declaration. But is

included in LSB 5.0 [L], and using pthread_atfork() is otherwise
problematic anyway [P].

One problem is that we were using it whenever __GLIBC__ is defined,
which is supposed to be defined only on an actual glibc, but uClibc
defines that macro, but it does not provide the symbol on its noMMU
variant.
We add a new configure check that will try to link a program that uses
that symbol to make sure it is present.

Fix vis family of functions to not leak
The code uses an internal helper function to avoid code repetition. But
to get there, the function takes a pointer to a pointer, so that the few
functions that require returning an allocated buffer can get hold of it
this way.
The problem is that the user might pass a NULL pointer and trigger an
internal allocation even if the functions are not expected to do so.
Add a new internal helper for non-allocations, that will assert that
condition, and make any other function that requires this behavior call
this one instead.

The NetBSD implementations have different prototypes to the ones coming

run-time. We provide now both interfaces with different prototypes as
different version nodes allow selecting them at compile-time, defaulting
for now to the OpenBSD one to avoid build-time breakage, while emitting
a compile-time warning. Later on, in 0.10.0, we will be switching the
compile-time default to the NetBSD version.

pidfile_fileno() in the man page. Move the definition of struct pidfh
from libutil.h into pidfile.c following upstream change.

Update getentropy() code from OpenBSD
Includes changes to handle the Linux syscall blocking when there is not

falling back to the alternative implementations. Man page URL reference

Fix build for openrisc with uClibc
uClibc defines EM_OR1K instead of EM_OPENRISC for the OpenRISC ELF
e_machine ID. Use EM_OR1K when EM_OPENRISC is not defined.
This fixes the following build failure:
In file included from nlist.c:44:0:

Fix handling of non-contiguous argv + envp in setproctitle()
The two arrays might not reference contiguous memory, and assuming they
are does break at least now on GNU/Hurd, which contains an unmapped
memory block between the memory used by the two arrays.
Just check that each element is strictly after the previous one, so that
we know there are no unmapped memory blocks inbetween.

Fix ELF definitions for MIPS in local-elf.h
Add a check for _MIPS_SIM inside the __mips__ #elif to detect mips64el
and use ELFCLASS64 in that case. Note that we can't use defined(__mips64)
here because that is also defined when the n32 ABI is in use, which uses
ELFCLASS32.

Fix broken mmap() usage in nlist() by switching to pread()
The offset is not page aligned, which makes mmap() return EINVAL on
Linux. Switch to use pread() which handles unaligned offset and non-page
sized reads, and because we are already loading parts of the executable
by read() calls, so there's not much point in using mmap() anyway.

Remove a.out support from nlist()
Some libc libraries do not have an <a.out.h> header. And a.out as an

supported systems, even if they might still support loading such
objects.
Remove the a.out support to increase portability.

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.
