MFC r367121:

Disable ssp raw test without ASAN

r366981 disabled ASAN when it might not be reliable (with an external
compiler), but this test is broken without ASAN so disable it completely
in that case.

MFC r366981:

Only use ASAN when using the in-tree compiler

When building FreeBSD 11 on a FreeBSD 12 system with
CROSS_TOOLCHAIN=llvm10 we end up trying to link against the packaged
version of the sanitizer library. This resulted in a requirement for
getentropy(3) which is not present in FreeBSD 11.

Rework check for libclang_rt to see if the needed library exists.

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

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.

Merge the projects/release-pkg branch to head.

This allows packaging the base system with pkg(8), including
but not limited to providing the ability to provide upstream
binary update possibilities for non-tier-1 architectures.

This merge is a requirement of the 11.0-RELEASE, and as such,
thank you to everyone that has tested the project branch.

Documentation in build(7) etc. is still somewhat sparse, but
updates to those parts will follow.

WITHOUT_TOOLCHAIN: Skip building of h_raw.

-fsanitize does not seem to work when a --sysroot is specified and there
is no <sysroot>/usr/lib/clang/3.8.0/lib/freebsd/libclang_rt.ubsan_standalone-*.a.

Fix regression in r291738: This really wants -lssp.

The normal LIBADD is ssp_nonshared. This also had a DPADD on LIBSSP which
does not actually exist, it is blank.

Fix LDADD/DPADD that should be LIBADD.

Not all targets support by clang have a tested or enabled ubsan yet.

Only enable h_raw on x86 targets for today so that a buildworld runs to
completion for clang enabled targets that are not x86. This should be
removed when validation of the sanitizer has occured for all targets
supported by FreeBSD and clang.

Disable h_raw/h_read with gcc

I forgot that these testcases fail with gcc 4.2.1; add a note to that effect

Don't install h_raw if dealing with clang 3.5.0+ to unbreak the tests2 Jenkins
job

The h_raw application doesn't do proper bounds checking without the option
being supplied via the build, which means that it doesn't throw signals and
fail as expected

For now, disable using -fsanitize=bounds for the libc ssp tests, when
using clang 3.5.0, until the runtime support (via compiler-rt) is added.
Otherwise, this would lead to link errors about missing support
libraries.

Add reachover Makefiles for contrib/netbsd-tests/lib/libc; this adds approximately
500 new testcases

Various TODOs have been sprinkled around the Makefiles for items that even need
to be ported (missing features), testcases have issues with building/linking, or
issues at runtime.

A variant of this code has been tested extensively on amd64 and i386
10-STABLE/11-CURRENT for several months without issue. It builds on other
architectures, but the code will remain off until I have prove it works on
virtual hardware or real hardware on other architectures
