2c6068194e cam_get_device, cam_open_device: make behavior simpler and more deterministic
Remove or re-work support for the several features from the past:
- remove incomplete support for trimming slice/partition names
- remove mapping from old device names "sd" and "st"
- remove whitespace trimming
- remove unconditional skipping of leading 'r' in a device name
- skip leading 'n' or 'e' only if the following device name matches
  a list of known devices that support no-rewind and eject-on-close
  features; currently this is only sa(4)
- reflect the above changes in comments in code and in cam(3)
- remove a note cautioning against use of cam_get_device and
  cam_open_device in cam(3)

24d351e408 Supply a valid Connect ID when issuing XPT_DEV_MATCH, which
according to my reading of the CAM draft is mandatory for
all CCB function calls and enforced by xptioctl() since at
least r168752. Previously we happened to use 0 as the Path
ID, causing the XPT_DEV_MATCH call to fail if there's no
SCSI bus 0. Basically the same bug was also fixed the same
way for camcontrol(8) as part of r126514.

b01a145dbf Better memory handling:
- It is acceptable to call free(3) when the given pointer itself
   is NULL, so we do not need to determine NULL before passing
   a pointer to free(3)
 - Handle failure of malloc(3)

ca6188876e string cleanup:
- fix a potential overrun made worse by rev 1.5 of camlib.h
 - change strncpy() and strcpy() calls to strlcpy()
 - use sizeof(string[]) instead of STRING_LEN to avoid future problems
 - get rid of an unused variable

Thanks to BDE for pointing out some of the problems.

b1c9f4a461 Make sure you don't have a file descriptor leak for the 'real'
underlying CAM device. This needs to be checked not only in
the open routine, but the device->fd has to be initialized
as well.

74090b93a6 cam_get_device() was returning 0 on failure, and 1 on success, while
camcontrol(8) and the documentation in camlib.c and cam(3) all expect
-1 on failure and 0 on success.  Updated camlib.c to return the values
specified by the documentation.

9cc9919f68 Add a "dummy light" (actually two dummy lights) to catch people who don't
have the passthrough device configured in their kernel.

This will hopefully reduce the number of people complaining that they can't
get {camcontrol, xmcd, tosha, cdrecord, etc.} to work.
