With ld.config.txt, we now have multiple built-in namespaces other than
the default namespace. Libs (and their dependents) listed in LD_PRELOAD
must be visible to those additional namespaces as well.
This also adds a debugging only feature: path to the linker config file
can be customized via LD_CONFIG_FILE environment variable. This works
only for debuggable builds.

I was intending to change our behavior to match POSIX, but reality convinced
me otherwise.
Also add missing argument names to the header file on the assumption they'll
be shown in Studio one day.

This also has a handful of style fixups, to make this file more
consistent. And removes __bionic_zero_size_is_okay_t, since there's a
better workaround available.

Since realpath no longer needs to be overloaded, we can restore the
upstream source to purity. We'll be able to do this with most of the
other functions when we pull a newer clang in.

This also throws in some reformatting to match the GCC FORTIFY style in
this file (e.g. 4 space standard indent).
Per b/36984245, some function protos are unwrapped beyond 100 chars, as
well.

Also:
- remove a NULL check. The bug that's been working around has been
fixed since clang r298431, and our compiler is built from r300080, and
- unwrap some function prototypes, per b/36984245.

...by inlining them.
Also fix a couple of harmless bugs in passing. I've added tests, but in
both cases I don't think it was actually possible to hit the bad behavior:
we'd hit another test and fail immediately after in an externally
indistinguishable way.

If the hardware debug support is missing from the CPU, the kernel can
end up in the state where it reports that it supports N(>0) watchpoints,
but the "maximum supported watchpoint size" is zero.
This is not a really sensible API, but it is what we have. I'm going to
speak to folks upstream about whether we can have it report something
more sensible, but that will take a while (if ever).
So, for the time being, detect this situation and treat it as if no
hardware watchtpoints/breakpoints are supported.

* TTYDEF_OFLAG referred to the BSD OXTABS constant instead of the Linux XTABS,
so references to it wouldn't compile.
* CEOL was incorrect (compared to `stty -a`).
* ttydefchars wouldn't compile (removed rather than attempt to fix something
of unclear utility).

Building ruby actually trips over both of these:
* if the RTLD_ constants aren't #defined, it uses its own incorrect values.
* if the REG_ constants aren't #defined, it confuses x86 with x86-64.
In all other places where we have enums in our headers, we already match
existing glibc practice.
