tests/gcov: demonstrate wrong coverage report after vfork/exec

Discovered in usr.bin/make, function Cmd_Exec.

The coverage test I ran on 2024-07-13 was still good. I don't remember
the exact version of NetBSD-current I was running back then.

With NetBSD-current from 2025-01-17, gcov does not report full coverage
data after a vfork/exec call. Running the test program inside ktrace
shows that after a vfork call, the child process writes its coverage data
back, probably right before the exec call, but the parent process
doesn't.

Running a child process through system(3) is not affected; there,
posix_spawn is used instead of vfork/exec.

ftp(1): Add test for custom HTTP header fields.

Based on a patch from Sunil Nimmagadda <sunil@nimmagadda.net>.

PR bin/58581: ftp(1) should allow specifying header fields in http
requests

tests: add a basic test for shmif_pcapin

The original author of the test is k-goda@IIJ. ozaki-r tweaked
the test to improve stability and added comments.

tests/stat: test the left-aligned and right-aligned 'S' format

mtree(8): Test the installed sets.

Except etc and xetc, which likely won't match for reasons that aren't
great, like etc including empty log files which in an installed
system have probably changed.

This test will probably fail, but we should make sure it doesn't!

tests/usr.bin/error: add basic tests for several error message styles

branches: 1.37.2;
Add ATF tests for realpath(1)

Note that realpath can act differently for root than for other users
(where an ordinary user will see EACCESS root just barrels right through).

The tests adapt themselves, when run as root, less error cases can be
tested than when run as some other user.

tests/compress: demonstrate truncation of target file

Reported by Giorgos Keramidas in PR#19722.

Fix release builds with MKARGON2=yes

This changes argon2 from a separately built library into a private
dependency of libcrypt and removes the argon2(1) utility (we already
have pwhash(1)). Giving libcrypt more library dependencies
complicates things (e.g. libcrypt is a dependency of openssl).
pthreads support gets disabled in argon2 for similar reasons.

For testing argon2, we rely on the libcrypt test suite.

Upgrade indent(1)

Merge all the changes from the recent FreeBSD HEAD snapshot
into our local copy.

FreeBSD actively maintains this program in their sources and their
repository contains over 100 commits with changes.

Keep the delta between the FreeBSD and NetBSD versions to absolute
minimum, mostly RCS Id and compatiblity fixes.

Major chages in this import:

- Added an option -ldi<N> to control indentation of local variable names.
- Added option -P for loading user-provided files as profiles
- Added -tsn for setting tabsize
- Rename -nsac/-sac ("space after cast") to -ncs/-cs
- Added option -fbs Enables (disables) splitting the function declaration and opening brace across two lines.
- Respect SIMPLE_BACKUP_SUFFIX environment variable in indent(1)
- Group global option variables into an options structure
- Use bsearch() for looking up type keywords.
- Don't produce unneeded space character in function declarators
- Don't unnecessarily add a blank before a comment ends.
- Don't ignore newlines after comments that follow braces.

Merge the FreeBSD intend(1) tests with our ATF framework.
All tests pass.

Upgrade prepared by Manikishan Ghantasala.
Final polishing by myself.

Add ATF tests for printf(1)

Two new test programs, one for the version of printf in /bin/sh
and one for the command /usr/bin/printf (t_builtin and t_command)

Each test program has 28 test cases (the same in each) of which
currently 27 pass, and 1 is skipped.

See the test scripts themselves for more information.

Add new c++ ATF tests in usr.bin/c++: t_hello

This is a copy of t_hello from usr.bin/cc.

Added tests:
- hello
- hello_pic
- hello_pie
- hello32

These tests do not use c++ runtime library functions.

Protect these tests with MKCXX.

PR bin/50934

Add a test program for the bug described in this PR.
This is the first pkill/pgrep/prenice test (more would be good!)

This test has been confirmed to work once the bug described in the PR
has been fixed, so the test is not marked "expected to fail" even
though initially that is what should happen.

Note: the test cana also fail if the system running the tests happens
to be running processes with names that match the patterns searched for
by the test, other than the test program itself. This is expected to be
unlikely.
