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.
* include/libc-pointer-arith.h: New file. Define
cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and
PTR_ALIGN_DOWN here.
* include/libc-internal.h: Definitions of above macros
moved from here. Don't include libc-diag.h anymore either.

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.

beginning.

* posix/wordexp.c (wordexp): Set we_wordc to zero initially unless
WRDE_REUSE flag is set.
(parse_param): Allow `*', `@', and numbers in parameter names.
(parse_dollars): Differentiate between arithmetic expansion and a
command substitution that starts immediately with a sub-shell
(like ``$((1+3))'' as opposed to ``$((echo);(ls))'').
(parse_param): Memory allocated with __alloca in a block was
referenced outside that block. Adjusted to use malloc/free.
(parse_param): Adjusted field-splitting algorithm so that there is
not necessarily a field split at the end of a parameter expansion.

* posix/wordexp.c (wordexp): If about to return WRDE_NOSPACE,
don't free words that have already been allocated.
(parse_param): A dollar sign on its own will never have a pattern
associated with it (like "${HOME%%/}" has), so don't try to free it.
(parse_glob): Attempt to glob when an unquoted `[' is found
(rather than an unquoted '{' (!)). Also for unquoted '?'.
(parse_glob): Sorted out quoting in a glob-able word.
(parse_param): Added $* and $@ handling.
