Jan Pokorný 41ae3e1267 Memleak fixes (#194) 
* memleak: ipc_socket: properly dispose local-scoped strndup values

Leaking memory was only possible when using filesystem sockets (see
use_filesystem_sockets function) and either:
- client is deliberately disconnecting from a server (continued run
  imposes a risk of exhausting memory)
- server is deliberately disconnecting from its client (ditto, but
  more substantial risk due to the common shared-resource nature
  of the server)

* memleak: ipc_socket: properly dispose inter-function strdup values

Leaking memory was only possible when the server accepted the client,
but didn't get (or was too shy) to talk to it prior to proceeding with
a disconnect.

* ipc_socket: care to explain what's going on with file name inference

Related to the code parts at hand, there was an investigation/fix in
the past, initiated by "make check" failure on FreeBSD 9 [rhbz#1256701].
Unfortunately, not only the magic constant being modified was not
explained in 1908e6c, but (one can derive because of a lack of solid
background of what's going on here, which might have caused that),
it was modified incorrectly at one instance (see also [PR165 comment]),
which was then reinstated in 7ebcb3d.

So, finally de-mystify those magic constants.  Also break the symmetry
between the client/server further with depending on the canonical
"request socket" alias at the server side (the former worked equally but
it was unnecessarily confusing and there's a risk this artificial alias
will get removed in the future).

libqb

What is libqb?

libqb is a library with the primary purpose of providing high-performance, reusable features for client-server architecture, such as logging, tracing, inter-process communication (IPC), and polling.

libqb is not intended to be an all-encompassing library, but instead provide focused APIs that are highly tuned for maximum performance for client-server applications.
