mkswap: possible to crash with SELinux relabeling support
When fgetfilecon() is failed with -ENODATA, this process does not
exit. However, "oldcontext" is not initialized in this case, so
context_new() will be called with uninitialized "oldcontext" at the
next.
Finally, it makes a segmentation fault, because context_new() have to
refer an incorrect memory region.
The attached patch fixes this matter using matchpathcon(). If we
cannot obtain actual file context due to -ENODATA, a context which is
returned by matchpathcon() is applied as oldcontext. Then, the type
of the context is relabeled to "swapfile_t" explicitly.

Add a missing period, a missing space, a comma and a word for clarity,
plus a period and an uppercase letter to match surrounding messages.
Further add a missing call to gettext, and undo an unneeded linewrap.
When hwclock --hctosys is started very early during the system startup,
with / still mounted read-only, and there was no /etc/adjtime file,
hwclock fails creating a default adjfile full of zeroes, and prints an
error message. I believe that such zero adjfile is not necessary,
because it means exactly the same as no adjfile at all.
The attached patch prevents creation of a zero adjfile, of course unless
something gets changed (this never happens during a --hctosys).

mount: prevent loop mounting the same file twice
The mount syscall prevents mounting the same device twice
to the same mountpoint. When loop mounting a file, for each
file a new loop device gets allocated, which prevents the detection
of loop mounting the same file to the same mountpoint twice.
The patch adds a check to prevent double mounts, if the same loopfile
is going to be mounted with the same offset to the same mountpoint.

This is done by calling cal with the extra day parameter like:
cal 14 9 1752
Note the tests were updated to use the new syntax.
Note also that this patch changes the -y option

the -[13] options are specified.
This matches the cal operation from bsdmainutils on debian

tailf: clean up gcc warnings & fix use of errno
Fix strict gcc warnings in tailf that come from using:
("-Wall -Wp,-D_FORTIFY_SOURCE=2")
tailf.c:111: warning: ignoring return value of 'fwrite', declared with attribute warn_unused_result
Also, tailf uses perror() for error reporting, but it inserts
an fprintf call first, so perror() is actually reporting the
result of the fprintf() call, not the failing call; change
the code to print the message by using strerror() instead.
Builds cleanly on x86_32 and x86_64.
