cc96e08e9d Issue #20: Improve socket name handling
The recently added cmp_sockaddr() function does not call stat(2) any
more to compare local AF_UNIX socket address paths, so not it is stable
enough to use for ordering sockaddr structs.

New function: real_sockaddr() converts the file path of a local AF_UNIX
file socket using realpath(3).  The MDP client uses it on the sender
address of every MDP reply packet it receives to ensure that symlinks in
the instance path do not cause MDP client failures.

Rename recently added socket_setname() function: make_local_sockaddr().

ae61a4f35c Issue #20: Make abstract sockets work
Finish the work started by Daniel in 2012, by using abstract local
AF_UNIX sockets on platforms that support them (Linux, Android).

Fix all sorts of bugs and issues that prevented the existing MDP and
Monitor client and server code from working with abstract socket names.

4937757d36 Improve Serval instance path operations
Replace form_serval_instance_path(), which takes a single 'path'
argument, with formf_serval_instance_path() and
vformf_serval_instance_path(), which take printf(3)-like arguments.
This supports more flexible instance path file names.

FORM_SERVAL_INSTANCE_PATH() macro works as before, but reimplemented

3b1ae5cbb0 Env vars SERVAL_KEYRING_PATH and SERVAL_KEYRING_READONLY
To support release signing operations without having to copy the release
keyring from its USB stick (into an instance directory), and reducing
the risk of corrupting the release keyring file while using it in-place.

2c6a14dd56 Delete all socket files on servald start
If serval does not close properly, socket files are kept in
/data/data/org.servalproject/var/serval-node. Therefore, we need to clean up
when servald starts.
