As reported in r218614 it's useful to have an indication of whether or not
BSD grep was built with GNU_GREP_COMPAT.

Bugs have been found in the fastmatch implementation as used in bsdgrep.
Some have been fixed (r316495) while fixes for others are in review
(D10098).
In comparison with the fastmatch implementation, Kyle Evans found that:
- regex(3)'s performance with literal expressions offers a speed
improvement over fastmatch
- regex(3)'s performance, both with simple BREs and EREs, seems to be
comparable
The regex implementation was imported in r226035, and the commit message
reports:
This is a temporary solution until the whole regex library is
not replaced so that BSD grep development can continue and the
backported code gets some review and testing. This change only
improves scalability slightly, there is no big performance boost
yet but several minor bugs have been found and fixed.
Introduce a WITH_/WITHOUT_BSD_GREP_FASTMATCH knob to support testing
of both approaches.

xmalloc was a debug malloc implementation, but the x{malloc,calloc,free}
functions default to calling the malloc(3) equivalents.
Instead of relying on this malloc shim, we can devise better ways to debug
malloc issues that aren't misleading upon initial inspection. (I.e., using
jemalloc's various built-in debugging capabilities.)

This is required by our FORTIFY_SOURCE implementation as it
does more inlining. As a rule of thumb, FORTIFY_SOURCE doubles
the number of inlines except that in grep inlining
blows up for some reason.
Some users build FreeBSD as non-root in Perforce workspaces. By default,
Perforce sets files read-only unless they're explicitly being edited.
As a result, the -f argument must be used to cp in order to override the
read-only flag when copying source files to object directories. Bare use of
'cp' should be avoided in the future.
Update all current users of 'cp' in the src tree.

Makefiles should not assume that source files can be overwritten. This is the
common case for Perforce source trees.
This is a followup commit to r211243 in the same vein.

If WITH_BSD_GREP is not set, it will be 'bsdgrep' and GNUgrep will be
'[ef]grep'. Otherwise, BSD-grep will be the grep family, and GNUgrep
will be 'gnugrep'.

- Makefile nit
- Add more CVS/SVN keywords to make it easier to track changes from NetBSD
in case they add further improvements
Approved by: delphij (mentor)
Obtained from: The NetBSD Project
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.
