59218eb770 - Revert strlcpy() changes to memcpy() because it's more efficient and
former may be safer but in this case it doesn't add extra
  safety [1]
- Fix -w option [2]
- Fix handling of GREP_OPTIONS [3]
- Fix --line-buffered
- Make stdin input imply --line-buffered so that tail -f can be piped
  to grep [4]
- Imply -h if single file is grepped, this is the GNU behaviour
- Reduce locking overhead to gain some more performance [5]
- Inline some functions to help the compiler better optimize the code
- Use shortcut for empty files [6]

4dc88ebedf Add BSD grep to the base system and make it our default grep.
Deliverables: Small and clean code (1,4 KSLOC vs GNU's 8,5 KSLOC),
              lower memory usage than GNU grep, GNU compatibility,
              BSD license.

TODO:         Performance is somewhat behind GNU grep but it is only
              significant for bigger searches.  The reason is complex, the
              most important factor is that GNU grep uses lots of
              optimizations to improve the speed of the regex library.
              First, we need a modern regex library (practically by adopting
              TRE), add support for GNU-style non-standard regexes and then
              reevalute the performance issues and look for bottlenecks.  In
              the meantime, for those, who need better performance, it is
              possible to build GNU grep by setting WITH_GNU_GREP.
