The result of a strdup() was stored in a global variable and not freed
before program exit. This is a follow-up to r343906. That change
attempted to plug these resource leaks but managed to miss a code path
on which the leak still occurs. Plug the leak on that path, too.

was incorrectly implemented leading to a possible double free.
It is possible for both the conditional free,
and the unconditional free added in r340044 to be done,
fix that by initializing uopt to NULL,
removing the conditional free,
and only using the unconditional free at the end.

- CID 1394815, CID 1305673: Dereference before null check - memory was
allocated and the allocation checked for NULL with a call to errx()
if it failed. Code below that was guaranteed that the pointer was
non-NULL, but there was another check for NULL at the exit of the
function (after the memory had already been referenced). Eliminate
the useless NULL check.
- CID 1007454, CID 1007453: Resource leak - The result of a strdup()
was stored in a global variable and not freed before program exit.
- CID 1007452: Resource leak - Storage intended to be allocated and
returned to the caller was never freed. This was the result of a
regression in the function signature introduced in r208648 (2010)
(thanks for that find, @cem!). Fixed by altering the function
signature and passing the allocated memory to the caller as
intended. This also fixes PR158794.
- CID 1008620: Logically dead code in newsyslog.c - This was a direct
result of CID 1007452. Since the memory allocated as described there
was not returned to the caller, a subsequent check for the memory
having been allocated was dead code. Returning the memory
re-animates the code that is the subject of this CID.
- CID 1006131: Unused value - in parsing a configuration file, a
pointer to the end of the last field was saved, but not used after
that. Rewrite to use the pointer value. This could have been fixed
by avoiding the assignment altogether, but this solutions more
closely follows the pattern used in the preceding code.

With r319610, sesutil started twiddling the bits of every SES device.
Not everything is a disk slot, there are also fan controllers, temperature
sensors, even power supplies, among other things controlled by SES.
Add a type check to make sure we are only operating on device slot and array
device slot elements. Other type elements will be skipped, but it would be
simple to add additional cases for controlling the ident LEDs of other
element types (which are not necessarily the same bits).
Rather than doing raw bit manipulation of an unstructured byte array using
unnamed numeric constants, leverage existing code abstractions.

While the warning is a false positive, it is possible to clarify the code by
always initializing the variable. This does also allow to make the sending
of the "beep" control sequence depend on the validity of its parameters.
I have left the redundant assignment of 0 to the now initialized variables
in place since this makes the code simpler to understand and does not add
any run-time overhead (the compiler completely removes the "else if" test
and the assignments).
There was an embedded literal escape character in a string, which messes up
diplaying the source code on a terminal that interprets ANSI sequences. The
literal escape has been replaced by \e (non-standard, but supported by all
relevant compilers, and already used in other source files in base).
