mount: cleanup canonicalize() usage
This patch renames canonicalize() to canonicalize_mountpoint() and
moves this function to realpath.c where is all cannonicalize code.
The canonicalize_mountpoint() function checks for special "none",
"proc", "swap" pseudo mointpoint.
The patch also adds a new generic canonicalize() function.

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.

cal: add support for highlighting an arbitrary date
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
to always print a full year, even if a month or
the -[13] options are specified.
This matches the cal operation from bsdmainutils on debian
and also allows one to print a full year while
highlighting a particular date.

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.

Only pull in locale.h as needed and move it to the common nls.h.
When editing a disk image, fdisk wants to ask the kernel to reread the
partition table which is useless and provokes an error, a wrong exit
code and some waiting. This annoys me as I can't check the return code
in my script and because I have to wait a few seconds each time.
This trivial patch makes it only do the ioctl on block devices.
It also simplifies code by dropping some workaround for kernel 1.2.x

A mount -f / creates two entries, one for LABEL and another
