799c5faa8b bsdgrep: create additional tests for coverage on recent fixes
Create additional tests to cover regressions that were discovered by
PRs linked to reviews D10098, D10102, and D10104.

It is worth noting that neither bsdgrep(1) nor gnugrep(1) in the base
system currently pass all of these tests, and gnugrep(1) not quite being
up to snuff was also noted in at least one of the PRs.

f48d142551 bsdgrep(1): Fix errors with invalid expressions
Invalid expressions with an ultimate compiled pattern length of 0 (e.g.,
"grep -E {") were not taken into account and caused a segfault while trying

5dc41cb0f2 bsdgrep(1): Rip out "xmalloc" bits
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.)

87c485cfb5 bsdgrep: fix matching behaviour
- Set REG_NOTBOL if we've already matched beginning of line and we're
  examining later parts

- For each pattern we examine, apply it to the remaining bits of the
  line rather than (potentially) smaller subsets

- Check for REG_NOSUB after we've looked at all patterns initially
  matching the line

- Keep track of the last match we made to later determine if we're
  simply not matching any longer or if we need to proceed another byte
  because we hit a zero-length match

- Match the earliest and longest bit of each line before moving the
  beginning of what we match to further in the line, past the end of the
  longest match; this generally matches how gnugrep(1) seems to behave,
  and seems like pretty good behavior to me

- Finally, bail out of printing any matches if we were set to print all
  (empty pattern) but -o (output matches) was set

00f060000f Fix a segfault in bsdgrep when parsing the invalid extended regexps "?"
or "+" (these are invalid, because there is no preceding operand).

When bsdgrep attempts to emulate GNU grep in discarding and ignoring the
invalid ? or + operators, some later logic in tre_compile_fast() goes
beyond the end of the buffer, leading to a crash.

Fix this by bailing out, and reporting a bad pattern instead.

430f7286a5 Merge ^/user/ngie/release-pkg-fix-tests to unbreak how test files are installed
after r298107

Summary of changes:

- Replace all instances of FILES/TESTS with ${PACKAGE}FILES. This ensures that
  namespacing is kept with FILES appropriately, and that this shouldn't need
  to be repeated if the namespace changes -- only the definition of PACKAGE
  needs to be changed
- Allow PACKAGE to be overridden by callers instead of forcing it to always be
  `tests`. In the event we get to the point where things can be split up
  enough in the base system, it would make more sense to group the tests
  with the blocks they're a part of, e.g. byacc with byacc-tests, etc
- Remove PACKAGE definitions where possible, i.e. where FILES wasn't used
  previously.
- Remove unnecessary TESTSPACKAGE definitions; this has been elided into
  bsd.tests.mk
- Remove unnecessary BINDIRs used previously with ${PACKAGE}FILES;
  ${PACKAGE}FILESDIR is now automatically defined in bsd.test.mk.
- Fix installation of files under data/ subdirectories in lib/libc/tests/hash
  and lib/libc/tests/net/getaddrinfo
- Remove unnecessary .include <bsd.own.mk>s (some opportunistic cleanup)

Document the proposed changes in share/examples/tests/tests/... via examples
so it's clear that ${PACKAGES}FILES is the suggested way forward in terms of
replacing FILES. share/mk/bsd.README didn't seem like the appropriate method
of communicating that info.

79b05c7ff0 Fix a bug in bsdgrep that caused the program to hang in a tight loop for
some combinations of command line options and search patterns.  The code was
examining regexec flags looking for a regcomp flag value.  The fix is to
look in the struct field where the decoded regcomp flag was stored when the
regex was compiled.

With this fix, it's possible to build WITHOUT_GNU_GREP_COMPAT and
WITH_BSDGREP and have a usable GPL-free grep (which of course lacks gnugrep
extensions).  It now passes the kyua tests except for one test that requires
the -z/--null-data gnu extension, and one test involving outputting context
lines across multiple files which appears to sometimes output an extra
delimiter line ("--") between matches (a rather obscure failure of a rather
obscure feature, so bsdgrep should be generally usable now).

blows up for some reason.

7a37b5fc17 Add a ${CP} alias for copying files in the build.
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.
