This test is done quite a bit across the tree, and the open-coded variants make it easy to have an
accidental mismatch between the length of the prefix being tested and the length actually passed to
strncmp().
This fixes an issue of that type comparing the server version against the prefix "u2.10", where the old
code used an incorrect length of 4.
init_socketpath() was building a sprintf() format string intended to be used by /DETACH to create the socket
file name. This included the actual socket path, plus a %d for the port, plus the sanitised tty name and
hostname.
Only one caller needed all this though - the /DETACH command - and the other callers (in scr-bx.c) just
wanted to truncate it to the actual socket path. The format string also wasn't safe - if the home directory
path, hostname or ttyname contained % characters these werent being escaped.
It simplifies things to have init_socketpath() just return the actual socket path, after creating the 'screens'
directory if necessary. This lets the code in scr-bx.c use it as-is, and removes the need for the global
socket_path variable. The code to include the sanitised tty name and hostname in the socket file name can
be moved to the create_ipc_socket() function.
There's no need to check access() for the socket path before trying to create it - just call mkdir() regardless,
since it will fail if the path already exists, which is fine.
This commit also adds error handling to the create_ipc_socket() function for the case where creation of the
socket file fails, and switches the chmod() and chown() for the opened file to the more appropriate fchmod()
and fchown().
This ensures that the saved-set-gid is also set, although this shouldn't
matter in practice since we always call execve() soon after, which
overwrites the saved-set-gid with the effective gid anyway.
This is preferable to using time_diff() to compare two timevals, because
time_diff() gives its result as a 'double' which only has 53 bits of
precision.
Also switch a couple of places from using time_diff() to using
this function.
Adding these in preparation for converting server->connect_time from time_t
to struct timeval. Also converts three existing open-coded versions over to
the new functions.
whether a context is empty, since the result is the same.

This includes all of the underlying support, but doesn't hook it up to the
/SERVER command yet, so it's not useable at this point.

like x86-64, where sizeof(int) != sizeof (void *). This involves correctly
casting every function pointer from the global table to the correct
function type, which has the added benefit of allowing type-checking of
function arguments and return values.
