Previously, Bionic's dl_phdr_info only included the first four
dl_iterate_phdr fields. Several other libc's have these additional fields:
unsigned long long dlpi_adds -- incremented when a library is loaded
unsigned long long dlpi_subs -- incremented when a library is unloaded
size_t dlpi_tls_modid -- TLS module ID
void* dlpi_tls_data -- pointer to current thread's TLS block or NULL
These extra fields are also exposed by glibc, musl, and FreeBSD. The
unwinder in libgcc.a, linked into shipping Android DSOs, has a
PC->eh_frame cache that activates if dl_phdr_info has the dlpi_adds and
dlpi_subs fields (indicated at run-time by a sufficiently-large size
argument to the callback).

This reverts commit 9af9120091 (a revert
of 079bff4fa5), now the versioner bug is
fixed.

This will make it easier to switch over to a virtual filesystem,
which should drastically improve performance.
This also fixes an issue with warning/error reporting.

I made a mistake caught by code review earlier, so let's try to be
safer by default.
This patch also moves all our "forwarding" headers to the guardless
just-include-the-other-thing style that we usually use. (Where we
have a comment explaining where the header comes from, I've kept
that.)
Change-Id: I37342cf5e2563c6a269b2ba61a697069b1c7913b
Some functions were added at different times on different platforms.
This should hopefully get most of them.

Also move some of the stuff that should be in <link.h> out of the
private "linker.h", to make it clearer that these are public API
known to gdb that we can't change.

This header is used on bionic build and should be propagated into
sysroot on toolchain rebuild. Discussion re. this header is here:
http://gcc.gnu.org/ml/gcc-patches/2012-08/msg00936.html
It is available already in mips NDK platforms:
development/ndk/platforms/android-9/arch-mips/include/link.h
