doc: Switch references from pkg-config to pkgconf
The former used to be the reference implementation, but it has been
stagnant to the point of not showing much signs of life. Switch to
the currently active and more complete implementation for references.

Because these symbols are not otherwise referenced, GCC would like
to remove them.

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.
