fdd5103348 Merge in two patches from Dave Cinege: 
the first is a cleanup of tar --exclude
    the second changes mount so mtab works more as it should, and
    also allows mount to use the traditional short form (i.e.
    'mount / -o remount,rw' now works.

While inside tar, I changed it to use getopt...

0b4551faf5 From Matt Kraai <kraai@alumni.carnegiemellon.edu>: 
Howdy,

Bug #1006 reports that

ln -s /tmp/foo .

does not work correctly.  In fact, it appears that any instantiation of

ln -s FILE... DIRECTORY

does not work.  The following patch adds support for this form, which
then fixes the particular instance noted in the bug report.

In the process, I needed the basename function.  This appears in the
string.h provided by glibc, but not uC-libc.  So I wrote my own to go in
utility.c, called get_last_path_component.  I also modified the basename
utility to use this function.

At some point it might be desirous to use the basename from the library
if it exists, and otherwise compile our own.  But I don't know how to do
this.

1ca41775bb Yanked out the cstring_alloc() and cstring_lineFromFile() functions from 
utility.c and replaced them with get_line_from_file() from the new grep.c.
Also changed declaration in internal.h and replaced instances of
cstring_lineFromFile() in dc.c and sort.c with get_line_from_file(). Tested
them and they worked fine.

5a728cfdfe + in the interest of robustness, I added 
utility.c :: cstring_alloc()
  utility.c :: cstring_lineFromFile()	/* they're at the bottom */
  so that I could read in lines of arbitrary length from FILE*s
  (instead of using fgets(huge_ass_buffer,...)).
+ I tested it out on sort, and it seems to be fine.

825aead68b Patch to make killall actually kill all PIDs with the specified name,
