Add mostly glibc and msl compatible secure_getenv. Return NULL if
issetugid() indicates the process is tainted, otherwise getenv(x). The
rational behind this is the fact that many Linux applications use this
function instead of getenv() as it's widely consider a, "best

The referenced symbols that provide init array boundaries are weak,
hidden, and undefined. The code that iterates over that arrays is not
used for the case when libc is compiled as dso.
This should fix linking with ld.bfd.

The current name was a historical curiosity that started when init array
support was added, and then the file appeared a convenient place for the
addition of the MI common code to csu. It is now referenced by name in
single place and the rename is easy, so do it.

Why? Most trivial point, it shaves around 600 bytes from the dynamic
binaries on amd64. Less trivial, the removed code is no longer part of
the ABI, and we can ship updates to it with libc updates. Right now most
of the csu is linked into the binaries and require us to do somewhat
tricky ABI compat when it needs to change. For instance, the init_array
change would be much simpler and does not require note tagging if we
have init calling code in libc.
This could be improved more, by splitting dynamic and static
initialization. For instance, &_DYNAMIC tests can be removed then.
Such change, nonetheless, would require building libc three times.
I left this for later, after this change stabilizes, if ever.

When doing a fully incremental build (with WITHOUT_CLEAN enabled), from
a commit before llvm 15 was merged (3264f6b88f), to a commit after
that, a number of .inc files were not regenerated. This could lead to
unexpected compilation errors when these .inc files were included from
llvm-project sources, similar to:
In file included from /usr/src/contrib/llvm-project/clang/lib/CodeGen/CGBuiltin.cpp:8268:
/usr/obj/usr/src/amd64.amd64/lib/clang/libclang/clang/Basic/arm_mve_builtin_cg.inc:279:18: error: no matching constructor for initialization of 'clang::CodeGen::Address'
Address Val2 = Address(Val1, CharUnits::fromQuantity(2));
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Work around this by making the .inc files dependent on the tblgen binary
used for generating them. E.g., we can relatively safely assume that if
the binary gets updated, the .inc files must also be updated. (Although
this is not 100% optimal, the gain by complicating things even more is
probaby not worth the effort.)

The prior code mistakently thought that the g_consumer that hung off the
provider we found were the right thing to use to find all the glabel
aliases for this node. However, the only way to find that is to iterate
through all the geoms that belong to the glabel geom class, looking for
those geoms with the same name as the provider with the right efimedia.
Do this in a way that caches glabel class, and allows for it to be
absent. Tighten the filter for mounted filesystems to only look
for the ones that are mounted on /dev/.. since the rest of the code
assumes that.
