Author: DJ Delorie <dj@redhat.com>

Add test-in-container infrastructure.
* Makefile (testroot.pristine): New rules to initialize the
test-in-container "testroot".
* Makerules (all-testsuite): Add tests-container.
* Rules (tests-expected): Add tests-container.
(binaries-all-tests): Likewise.
(tests-container): New, run these tests in the testroot container.
* support/links-dso-program-c.c: New.
* support/links-dso-program.cc: New.
* support/test-container.c: New.
* support/shell-container.c: New.
* support/echo-container.c: New.
* support/true-container.c: New.
* support/xmkdirp.c: New.
* support/xsymlink.c: New.
* support/support_paths.c: New.
* support/support.h: Add support paths prototypes.
* support/xunistd.h: Add xmkdirp () and xsymlink ().
* nss/tst-nss-test3.c: Convert to test-in-container.
* nss/tst-nss-test3.root/: New.
(note: support/ already present, not needed; sample test not included)

+# The intention here is to do ONE install of our build into the
+# testroot.pristine/ directory, then rsync (internal to
+# support/test-container) that to testroot.root/ at the start of each
+# test. That way we can promise each test a "clean" install, without
+# having to do the install for each test.
+#
+# In addition, we have to copy some files (which we build) into this
+# root in addition to what glibc installs. For example, many tests
+# require additional programs including /bin/sh, /bin/true, and
+# /bin/echo, all of which we build below to limit library dependencies
+# to just those things in glibc and language support libraries which
+# we also copy into the into the rootfs. To determine what language
+# support libraries we need we build a "test" program in either C or
+# (if available) C++ just so we can copy in any shared objects
+# (which we do not build) that GCC-compiled programs depend on.
