e5f71a07e4 Revert (partial) r281123, r281125: 
sort: style knits / cleanups.

Our style guide(9) specifies that in absence of local variables
an empty line must be inserted.

3e16491d77 Make sure to not skip any argument when converting from deprecated 
+POS1, -POS2 to -kPOS1,POS2, so that sort +0n gets translated to sort -k1,1n
as it is expected

bf70becee6 More -Wmissing-variable-declarations fixes. 
In addition to adding `static' where possible:

- bin/date: Move `retval' into extern.h to make it visible to date.c.
- bin/ed: Move globally used variables into ed.h.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.
- usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.

c66bbc9143 Add a BSD-licensed sort rewrite that was started by me and later completed 
with the major functionality and optimizations by Oleg Moskalenko.
It is compatible with the latest version of POSIX and the current GNU sort
version that we have in base.  Beside this, it implements all the
functionality introduced in later versions of GNU sort.  For now, it will
be installed as "bsdsort", keeping GNU sort as the default sort
implementation.
