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

b7185a294f Fix keyring SEGV bug 
Sometimes, when adding a PIN to a keyring (eg, when opening a keyring
file), a SEGV would be caused while trying to validate the MAC for an
entry which apparently had zero keypair entries.

Changed some keyring struct 'int' fields to 'unsigned int', to ensure
that comparison logic behaves as expected.

Refactored some keyring code for more clarity and code maintenance
safety.

Added TODO comment about keyring file format non-back-compatibility.

390655580d Add 'rhizome delete' and 'rhizome clean' commands 
sqlite_void_exec() and its ilk now return the count of changed rows, not
just zero, on success

sqlite_exec_prepared() and its ilk now return the count of rows (number
of step results SQLITE_ROW), instead of just zero, on success

rhizome_clean() function now produces an optional report of its changes

rhizome_fail_write() and rhizome_finish_write() now log WARNings not
ERRORs if the SQL DELETE FROM FILES or DELETE FROM FILEBLOBS statements
fail

Refactor rhizome_open_read() to use sqlite_exec_int64()

Ensure that 'rhizome extract' and 'rhizome dump' commands return exit
status of 1 in "not found" conditions, not 255, which is reserved for
errors

Test cases for four new commands: 'rhizome delete bundle', 'rhizome
delete manifest', 'rhizome delete payload' and 'rhizome delete file'
