This makes pa_make_secure_dir() create any missing parent directories in
the given path as well. This is useful, for example, on a pristine
system with a clean $HOME that needs ~/.config/pulse/ to be created when
~/.config does not exist.
If ~/.pulse/ already exists we stick to it in order not to lose
configuration and so that pulse configuration may still be shared across
the network with different PA versions.
XDG_SESSION_COOKIE was supposed to be used for access control to the
session and should not be exposed to other users.
Replace usage of XDG_SESSION_COOKIE by XDG_SESSION_ID which is the right
choice here since it is actually a proper session ID that may be
published.
When the runtime path gets long (which can happen on some NFS
mounts where $HOME is not just /home/$USER), it can grow
longer the 108 char limit imposed by sockaddr_un.sun_path.
This just calls realpath which should ultimately point into
/tmp in most cases and result in a much smaller path.
Only do this when we are adding on a name component to the
runtime path so creating the actual symlink will still get
the original, long name, but this shouldn't be a problem
as it never goes into the sockaddr_un.sun_path.

This adds a pa_str_in_list() to check for a given string in a
space-separated list of strings. For now, this is merely present to
avoid duplication of role matching code (intended roles can be a
space-separate list) across modules.
On 64-bit systems LONG_MAX is greater than the largest possible value of a
uint32_t variable, which caused the compiler to warn about a comparison that is
always false. On 32-bit systems pa_atou() can return a value that will overflow
when assigned to e->volume_limit, which has type long, so the comparison was
necessary.
This dilemma is resolved by using pa_atol() instead of pa_atou().

The check whether POSIX socket.h or WIN32 winsock2.h must be included can be
made centrally. The downside is that some functionality of e.g. arpa/inet.h is
also implemented in winsock.h, so that some files that don't use socket
functions, but do use inet.h functions, must also include pulsecore/socket.h.
(as well as arpa/inet.h)
In theory putenv could be used to handle freeing of strings yourself, but this
was not done in PulseAudio. That leaves no advantages in using putenv. With
setenv you're at the mercy of the implementation whether the strings leak, but
at least that is better then a certain leak, as it was before.
