Integrate tools/regression/lib/libc/nss into the FreeBSD test suite as

lib/libc/tests/nss

- Convert the testcases to ATF
- Do some style(9) cleanups:
-- Sort headers
-- Apply indentation fixes
-- Remove superfluous parentheses
- Explicitly print out debug printfs for use with `kyua {debug,report}`; for
  items that were overly noisy, they've been put behind #ifdef DEBUG
  conditionals
- Fix some format strings

MFC after: 1 week

-A brief how-to
---------------
-
-Each nsswitch regression test does 2 kinds of actions:
-1. It runs a series of queries and tests the correctness of results.
-   There are 2 basic criteria which are used for that:
-      - numbers must be in the correct range
-      - certain pointers should not be NULL
-
-2. It makes a snapshot of the results of all queries that were made.
-   The idea of snapshots is to test that nsswitch-related function
-   calls behave equally (i.e. return same results for the same queries)
-   between system upgrades. When the test is executed and the snapshot is
-   already created, the test will compare the result of each query with
-   the appropriate result from the snapshot and will signal if they
-   differ.
-
-In order for nsswitch tests to be as useful as possible you should use
-them in the following way:
-
-Step 1 (before upgrading your system).
-Build the tests with "make" command and execute them with "prove -v"
-command. If there are errors during the execution, then appropriate
-nsswitch functions should be checked. Note, that errors on this state
-can happen only if the particular function return incorrect data.
-
-After the stage 1 a number of "snapshot_[test name]" files will appear
-in your test folder.
-
-Step 2 (after upgrading you system).
-Rebuild the tests with "make clean; make" command and execute them
-again with "prove -v" (check that "snapshot_[test name]" files
-are in the same folder with tests). On this stage regression tests
-will catch not only the correctness errors, but will also determine
-the changes in nsswitch functions behaviour.
-
-In case of the test failure you will get the following message:
-
-To get more details about the error you should do the following:
-Step 1. Run the test alone with debug output enabled.
-Step 2. Mail the snapshot file and the debug test output to the
-freebsd-current@ mailing list.
-
-Example testing session for getpwXXX() family of functions
-----------------------------------------------------------
-1. make
-
-2. prove -v ./test-getpw.t
-   
-   test-getpw....1..8
-   ok 1 - getpwnam()
-   ok 2 - getpwuid()
-   ok 3 - getpwent()
-   ok 4 - getpwent() 2-pass
-   ok 5 - building snapshot, if needed
-   ok 6 - getpwnam() snapshot
-   ok 7 - getpwuid() snapshot
-   ok 8 - getpwent() snapshot
-   ok
-   All tests successful.
-   Files=1, Tests=8,  1 wallclock secs ( 0.00 cusr +  0.20 csys =  0.20 CPU)
-
-
-3. Upgrading the system.
-
-4. make clean; make
-
-5. prove -v ./test-getpw.t (suppose that something has gone wrong)
-
-   test-getpw....1..8
-   ok 1 - getpwnam()
-   ok 2 - getpwuid()
-   ok 3 - getpwent()
-   ok 4 - getpwent() 2-pass
-   ok 5 - building snapshot, if needed
-   not ok 6 - getpwnam() snapshot
-   ok 7 - getpwuid() snapshot
-   not ok 8 - getpwent() snapshot
-   FAILED tests 6, 8
-           Failed 2/8 tests, 75.00% okay
-   Failed 1/1 test scripts, 0.00% okay. 2/8 subtests failed, 75.00% okay.
-
-6. We see that test number 6 failed. According to get-getpw.t, this test
-   is executed like this:
-   do_test 6 'getpwnam() snapshot'           '-n -s snapshot_pwd'
- 
-   To determine why the test has failed, we need to run it in debug mode -
-   it means adding "-d" to the options list.
-
-7. ./test-getpw -dn -s snapshot_pwd
-   ...
-   testing getpwnam() with the following data:
-   toor:*:0:0:0::ne-again Superuser:/root::0:4831
-   testing correctness with the following data:
-   toor:*:0:0:0::Bourne-again Superuser:/root::0:4831
-   correct
-   not ok
-
-8. Here we can see that the data from snapshot (first "toor" line) and
-   the data received from the getpwnam() call (second "toor" line) are
-   different. It is the reason why the test has failed. If you can't
-   (or don't want) to investigate the problem by yourself, mail
-   the test debug output and the snapshot file to the developers list.
- 
-Notes on using standalone nsswitch tests
-----------------------------------------
-
-All nsswitch tests have [-d] optional command line argument which enables
-debug output. The debug output can be extremely helpful to determine the
-cause of test failure.
-
-In all nsswitch tests -s <file> command line argument specifies the
-snapshot file. If this file doesn't exist, it would be built during
-test execution. If it already exists then it will be used to check
-the results of particular function calls. This argument is mostly
-optional, but some tests (test-getaddr and test-getusershell) force
-it to be specified.
-
-test-gethostby and test-getaddr require the list of hostnames, that should
-be queried during the test. This list must be specified via -f <file>
-command line argument. Each hostname should occupy exactly one line
-in the file.
