Avoid redefining _REENTRANT under sanitizers

Switch away from -Wno-macro-redefined which was Clang specific.

Expand the -Wno-macro-redefined usage to MKLIBCSANITIZER

_REENTRANT can be redefined and this is considered as an error.

Enhance the support of LLVM sanitizers

Define _REENTRANT for MKSANITIZER build. This is needed for at least stdio
code. This caused new build issued with duplicated symbols in few places
and rump kernel code picking different code paths borrowed from libc.
Handle all this in one go.

Add bsd.sanitizer.mk to share common code used by programs and libraries.

Switch from realall to beforeinstall target in .syms files. This is more
reliable in MKSANITIZER.

Use daemon(3) instead of the experimental daemon2_fork() and
daemon2_detach(). Now that newer versions of daemon2_fork() and
daemon2_detach() are used in nfsd, where two-stage daemonization is
actually needed, there is no longer any reason for h_dns_server to
serve as a test case and example of their use.

Add a cleanup routine because if a test fails, the script exits and the
rest of the code is not executed.
Note that the cleanup routine is executed in a separate shell so environment
variables are not propagated and need to be set again.

allow testing of files other than those in /etc

To test e.g., the file "/some/where/protocols" instead of "/etc/protocols",
set TEST_FILE=/some/where/protocols in your environment.

Note: this now compares the contents of the file you gave versus what
getprotoent(3)/getservent(3) uses (which still is /etc/protocols via
h_protoent.c / /etc/services or /var/db/services.cdb via h_servent.c).

When you have expected changes in the services or protocols file that
you're generating, this necessarily produces a difference. To really
allow testing the file versus what the library function returns, you'd
have to install the file on the system running the test, but at least
with this change you can now generate the file and verify that it didn't
caused unexpected differences.

libc fallback is known to not produce nice alias entries. Avoid spurious
failures when testing in an empty chroot by requiring the services db.
