In test-conainer we should set errno to 0 before calling strtol,
and check after with TEST_COMPARE.
In tst-support_capture_subprocess we should set errno to 0 before
checking it after the call to strtol.
Tested on x86_64.

Expand the support infrastructure:
- Create $(complocaledir) in the testroot.pristine to support localedef.
- Add the variable $complocaledir to script support.
- Add the script command 'mkdirp'.
All localedef tests which run with default paths need to have the
$(complocaledir) created in testroot.pristine. The localedef binary
will not by itself create the default path, but it will write into
the path. By adding this we can simplify the localedef tests.
The variable $complocaledir is the value of the configured
$(complocaledir) which is the location of the compiled locales that
will be searched by the runtime by default.
The command mkdirp will be available in script setup and will
be equivalent to running `mkdir -p`.
The variable and command can be used to write more complex tests.

I'm debugging a situation where lots of tests using test-container fail
and it's possible knowing errno would help understand why.

exec <path_to_test_binary> [optional_argv_0]
copies test binary to specified location and runs it from
there. If the second argument is provided, that will
be used for argv[0]
cwd <directory>
attempts to chdir(directory) before running test
Note: "cwd" not "cd" as it takes effect just before the
test binary runs, not when it's encountered in the script,
so it can't be used as a path shortcut like "cd" would imply.
cleanup: use xstrdup() instead of strdup()

If WAIT_FOR_DEBUGGER is set to a non-zero value in the environment,
any test that runs will print some useful gdb information and wait
for gdb to attach to it and clear the "wait_for_debugger" variable.

One of the implicit-fallthrough warnings from compiling glibc with
-Wextra appears to indicate an actual bug: the test-container code
could fall through inappropriately if execlp returns (which only
occurs on error). This patch adds appropriate error handling in this
case to avoid that fall-through.
Tested for x86_64.
* support/test-container.c (recursive_remove): Use FAIL_EXIT1 if
execlp returns.
During postclean.req testing it was found that the fork in the
parent process (after the unshare syscall) would fail with ENOMEM
(see recursive_remove() in test-container.c). While failing with
ENOMEM is certainly unexpected, it is simply easier to refactor
the design and have the parent remain outside of the namespace.
This change moves the postclean.req processing to a distinct
process (the parent) that then forks the test process (which will
have to fork once more to complete uid/gid transitions). When the
test process exists the cleanup process will ensure all files are
deleted when a post clean is requested.

[BZ #23948]
* support/test-container.c: Move postclean step to before we
change namespaces.
The test-container.c file assumes that ld.so is always named
something like /elf/ld-linux-*.
But e.g. on s390x it is named ld64.so.1 or ld.so.1 on s390.
There are other architectures like power or mips with similar names.
This patch introduces the new global variable support_objdir_elf_ldso
which contains the absolute path to the runtime linker used by the
testsuite, e.g. OBJDIR_PATH/elf/ld-linux-x86-64.so.2.
The check in test-container.c is now comparing against this path.
Without this patch, test-container.c is searching invalid files / directories
and fails to find glibc/nss/tst-nss-test3.root/tst-nss-test3.script.
Then the test tst-nss-test3 fails!

copy_file_range can't be used to copy a file from glibc source directory
