a34817457f Improve the _FILE_OFFSET_BITS docs and link to them.
We're still seeing lots of confusion. People do seem to look as far as
the headers, but stop there. So let's try a bit harder to point them in
the right direction.

Also explicitly state that removing _FILE_OFFSET_BITS=64 is the
behavior-preserving fix for compilation problems when upgrading to NDK
r15 or later.

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

This reverts commit 079bff4fa5.

Broke builds with SANITIZE_HOST=address with an asan failure in versioner.

00fedf5879 Undo recent _FILE_OFFSET_BITS=64 changes.
We had several bugs filed saying "if I set _FILE_OFFSET_BITS=64 when
targeting an API < L, various functions are missing". Instead of
saying "yes, they are", we quietly just modified the header files to
expose the non-64-bit variants. This makes no sense. We can't just say
"oh, yeah, we don't have a version of this function that agrees with
your calling code about how large off_t is, but here's a version that
doesn't: I'm sure it'll be fine".

_FILE_OFFSET_BITS=64 on Android LP32 has always been a game of chance,
but that game should be "are all the functions my code needs available
at compile time?", not "will my code actually work at run time?".

3645e71a43 Only rename sendfile to sendfile64 if we're L or newer.
Without this, setting __FILE_OFFSET_BITS to 64 and targeting pre-L
made sendfile entirely unavailable.

68dc20d411 Implement _FILE_OFFSET_BITS (mostly).
I still don't think we can make stdio's fseeko and ftello work, but we can
have everything else, and very few programs use fseeko/ftello (and they can
just refrain from using _FILE_OFFSET_BITS and be no worse off than they are
today).
