Fix compiler warnings

Fix compiler warnings about socket usage

Correct the data types used for the socket declaration.  We use AF_UNIX
sockets so we use struct sockaddr_un, but we need to cast to struct
sockaddr for the socket API.

Fix compiler warnings about sign-compare

Fix two occurences of signed - unsigned comparison by casting the values
accordingly.  Note that the cast is legal as the first parts of both
conditional statements make sure the value is not negative before
casting to unsigned.

While at it, add strtol error checking.

Fix compiler warnings about string functions

Add string.h to src/daemon/dlt_daemon_unix_socket.c, because it was
unaware of memcpy and strerror.  While at it, change unsafe use of
sprintf to proper dlt_vlog and remove the char buffer.

Fix compiler warnings about unused-*

Fix two unused-variable and one unused-parameter warning.  While at it,
change the #ifdef to not run into an empty block.  Simply reverse the
condition and enclose the complete else with the #ifdef.

POSIX: Use memset instead of bzero

"The bzero() function is deprecated (marked as LEGACY in POSIX.1-2001);
use memset(3) in new programs."

Use memset instead of bzero and remove any occurrence from DLT.  Include
of header "strings.h" that has bzero is also removed.
