60fd3450bf Fix the *rand48 functions on LP64.
I reported the mrand48 bug upstream, and 'matt' fixed the whole family
of functions!

eb847bc866 Fix x86_64 build, clean up intermediate libraries.
The x86_64 build was failing because clone.S had a call to __thread_entry which
was being added to a different intermediate .a on the way to making libc.so,
and the linker couldn't guarantee statically that such a relocation would be
possible.

  ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC

This patch addresses that by ensuring that the caller and callee end up in the
same intermediate .a. While I'm here, I've tried to clean up some of the mess
that led to this situation too. In particular, this removes libc/private/ from
the default include path (except for the DNS code), and splits out the DNS
code into its own library (since it's a weird special case of upstream NetBSD
code that's diverged so heavily it's unlikely ever to get back in sync).

There's more cleanup of the DNS situation possible, but this is definitely a
step in the right direction, and it's more than enough to get x86_64 building
cleanly.

6b3f49a537 Upgrade to current NetBSD popen/pclose.
This gets us back to using vfork now our ARM vfork assembler stub is
fixed, and adds the missing thread safety for the 'pidlist'.

c30396f5f2 libc: Fix alphasort() signature (and implementation).
The declaration for alphasort() in <dirent.h> used the deprecated:

  int alphasort(const void*, const void*);

while both Posix and GLibc use instead:

  int alphasort(const struct dirent** a, const struct dirent** b);

See: http://pubs.opengroup.org/onlinepubs/9699919799/functions/alphasort.html

This patch does the following:

- Update the declaration to match Posix/GLibc
- Get rid of the upstream BSD code which isn't compatible with the new
  signature.
- Implement a new trivial alphasort() with the right signature, and
  ensure that it uses strcoll() instead of strcmp().
- Remove Bionic-specific #ifdef .. #else .. #endif block in
  dirent_test.cpp which uses alphasort().

Even through strcoll() currently uses strcmp(), this does the right
thing in the case where we decide to update strcoll() to properly
implement locale-specific ordered comparison.

eac9eb462e Add getdelim(3) and getline(3) to bionic
Some userspace programs (e.g. perf) need getline.

Changes:
() add getdelim.c, getline.c from NetBSD (http://netbsd.org/) under the
NetBSD Foundation's (TNF) license ("2 clause" Berkeley-style license).
() add stub for reentrant.h header that is needed by getdelim.c
() add tests for getdelim(3) and getline(3).
() update NOTICE file.

f8b3a920a8 Revert "Revert "Switch to NetBSD's strxfrm(3).""
This reverts commit 8793e7c7d2,
and fixes the build by building upstream NetBSD source as a
separate library that's then swallowed whole into libc_common.

be1d78b0dc Switch to NetBSD's strxfrm(3).
There were two bugs in our implementation. Intel found one, but another
remainined, and tracking upstream is the way forward for functions where
we add no value.
