build: Support platforms without symbol versioning
The .symver directive is ELF-specific. On non-ELF platforms, work around
this with __attribute__((__alias__)) for the default symbol, and ignore
the variant versioned symbols.

build: Use __register_atfork() only if really available
This is a glibc-specific symbol that has no public declaration. But is
being used by the OpenBSD and this implementation as a hack to avoid
having to link against the pthread library. This interface is at least
included in LSB 5.0 [L], and using pthread_atfork() is otherwise
problematic anyway [P].
[L] <https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/baselib---register-atfork.html>
[P] <http://austingroupbugs.net/view.php?id=851>
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.
Closes: !2

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.

Fix strnvis() and strnunvis() NetBSD ABI break
The NetBSD implementations have different prototypes to the ones coming
from OpenBSD, which will break builds, and have caused segfaults at
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.

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.

build: Remove hard requirement for GNU .init_array section support
In case the support is not available, just stop building the
libbsd-ctor.a library, which is a nice to have thing, but should not
have been a hard requirement from the start. This should allow to
build libbsd on non-glibc based systems using another libc.

Add funopen() function
This is a wrapper over the glibc fopencookie() function.
We diverge from the FreeBSD, OpenBSD and DragonFlyBSD declarations,
because seekfn() there wrongly uses fpos_t, assuming it's an integral
type, and any code using that on a system where fpos_t is a struct
(such as GNU-based systems or NetBSD) will fail to build. In which case,
as the code has to be modified anyway, we might just as well use the
correct declaration.

Fix dehumanize_number() to correctly detect overflows
Do not allow numbers greated than INT64_MAX and smaller than INT64_MIN.

Move setproctitle() automatic initialization to its own library
The automatic initialization cannot be part of the main shared library,
because there is no thread-safe way to change the environ global
variable. This is not a problem if the initializaion happens just at
program load time, but becomes one if the shared library is directly or
indirectly dlopen()ed during the execution of the program, which could
have either kept references to the old environ or could change it in
some other thread. This has been observed for example on systems using
Samba NSS modules.
To avoid any other possible fallout, the constructor is split into a
new static library that needs to be linked explicitly into programs
using setproctitle(). As an additional safety measure the pkg-config
linker flags will mark the program as not allowing to be dlopen()ed
so that we avoid the problem described above.

Create a shallow copy of environ before replacing it in setproctitle()
Because clearenv() or setenv() might free the environ array of pointers,
we should make sure to copy it so that we can access it later on when
doing the deep copy via setenv().

Force setproctitle() into .init_array section
The GNU .init_array support is an extension over the standard System V
ABI .init_array support, which passes the main() arguments to the init
function.
This support comes in three parts. First the dynamic linker (from glibc)
needs to support it. Then function pointers need to be placed in the
section, for example by using __attribute__((constructor)), that the
compiler (gcc or clang for example) might place in section .ctors and
the linker (from binutils) will move to .init_array on the output
object, or by placing them directly into .init_array by the compiler
when compiling. If this does not happen and the function pointers end
up in .ctors, then they will not get passed the main() arguments, which
we do really need in this case.
But this relies on recent binutils or gcc having native .init_array
support, and not having it disabled through --disable-initfini-array.
To guarantee we get the correct behaviour, let's just place the function
pointer in the .init_array section directly, so we only require a recent
enough glibc.
