This patch replaces the fork+exec by posix_spawn on wordexp, which
allows a better scability on Linux and simplifies the thread
cancellation handling.
The only change which can not be implemented with posix_spawn the
/dev/null check to certify it is indeed the expected device. I am
not sure how effetive this check is since /dev/null tampering means
something very wrong with the system and this is the least of the
issues. My view is the tests is really out of the place and the
hardening provided is minimum.
If the idea is still to provide such check, I think a possibilty
would be to open /dev/null, check it, add a dup2 file action, and
close the file descriptor.
Checked on powerpc64le-linux-gnu and x86_64-linux-gnu.
* include/spawn.h (__posix_spawn_file_actions_addopen): New
prototype.
* posix/spawn_faction_addopen.c (posix_spawn_file_actions_addopen):
Add internal alias.
* posix/wordexp.c (create_environment, free_environment): New
functions.
(exec_comm_child, exec_comm): Use posix_spawn instead of fork+exec.
* posix/wordexp-test.c: Use libsupport.
Once wordexp switches to posix_spawn, testing for command execution
based on fork handlers will not work anymore. Therefore, move these
subtests into a new test, posix/tst-wordexp-nocmd, which uses a
different form of command execution detection, based on PID
namespaces.

posix/wordexp-test.c used libc-internal.h for PTR_ALIGN_DOWN; similar
to what was done with libc-diag.h, I have split the definitions of
cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN
to a new header, libc-pointer-arith.h.
It then occurred to me that the remaining declarations in libc-internal.h
are mostly to do with early initialization, and probably most of the
files including it, even in the core code, don't need it anymore. Indeed,
only 19 files actually need what remains of libc-internal.h. 23 others
need libc-diag.h instead, and 12 need libc-pointer-arith.h instead.
No file needs more than one of them, and 16 don't need any of them!
So, with this patch, libc-internal.h stops including libc-diag.h as
well as losing the pointer arithmetic macros, and all including files
are adjusted.

cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and

The function wordexp() fails to properly handle the WRDE_NOCMD
flag when processing arithmetic inputs in the form of "$((... ``))"
where "..." can be anything valid. The backticks in the arithmetic
epxression are evaluated by in a shell even if WRDE_NOCMD forbade
command substitution. This allows an attacker to attempt to pass
dangerous commands via constructs of the above form, and bypass
the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD
in exec_comm(), the only place that can execute a shell. All other
checks for WRDE_NOCMD are superfluous and removed.
We expand the testsuite and add 3 new regression tests of roughly
the same form but with a couple of nested levels.
On top of the 3 new tests we add fork validation to the WRDE_NOCMD
testing. If any forks are detected during the execution of a wordexp()
call with WRDE_NOCMD, the test is marked as failed. This is slightly
heuristic since vfork might be used in the future, but it provides a
higher level of assurance that no shells were executed as part of
command substitution with WRDE_NOCMD in effect. In addition it doesn't
require libpthread or libdl, instead we use the public implementation
namespace function __register_atfork (already part of the public ABI
for libpthread).
Tested on x86_64 with no regressions.

WRDE_REUSE flag is set.
(parse_param): Allow `*', `@', and numbers in parameter names.

associated with it (like "${HOME%%/}" has), so don't try to free it.
