Dan Albert
210331d976 Replaces vfork() implementation with fork()
vfork() was removed from POSIX 2008, so this replaces its implementation
with a call to fork().

47ba295b06 Rewrite and hide longjmperror.
This shouldn't be public API, isn't supported on x86/x86_64, and it's
unlikely anyone would have actually seen the message before anyway.
Using __libc_fatal makes it much more likely to be seen.

the VM, but if we're seriously looking at other malloc implementations,
that's something we're going to have to fix.

72bbd42357 Support for jemalloc to replace dlmalloc.
To use jemalloc, add MALLOC_IMPL = jemalloc in a board config file
and you get the new version automatically.

Update the pthread_create_key tests since jemalloc uses a few keys.
Add a new test to verify memalign works as expected.

48ee47ce25 Removes RTTI support from libc
Our type_info stub implementation is incompatible with the libc++ headers. Since
we don't need this support internally and anyone that wants RTTI support will
have to use libc++ anyway, this can be safely removed.

4c2da039ba Fix the newly-introduced warning and turn on -Werror.
I cleaned up most of our warnings last week but forgot to turn on -Werror,
so of course we're getting new warnings already. I've left -Werror commented
out in those places where we still have warnings to deal with before we can
turn on -Werror.

15b641a267 Move libstdc++ into libc.
The Android build system always links against libstdc++.so anyway. Having
operator new and operator delete in a separate library means we can't use
constructors and destructors on heap-allocated objects inside the C library,
which is quite an unfortunate limitation.

This will be cheaper too; on LP64 we can stop linking against the [now empty]
libstdc++.so giving the dynamic linker one less library to worry about for
every process.

There's precedent too --- we already have no libpthread or librt.

For now I'm leaving the include files where they are, and I'm generating a
dummy libstdc++.so and libstdc++.a. We can come back and clean that up later
if all goes well.

5c8c88dd8d Use the NetBSD inet_ntop until the OpenBSD bug is fixed.
Stupidly I found this bug by accident when writing the existing
tests, but I didn't think any real code would hit it. It turns
out that libcore always uses an INET6_ADDRSTRLEN-sized buffer
even when working with AF_INET addresses.

Add following functions:
bcopy, memcpy, memmove, memset, bzero, memcmp, wmemcmp, strlen,
strcpy, strncpy, stpcpy, stpncpy.
Create new directories inside arch-x86 to specify architecture: atom,
silvermont and generic (non atom or silvermont architectures are treated like generic).
Due to introducing optimized versions of stpcpy and stpncpy,
c-implementations of these functions are moved from
common for architectures makefile to arm and mips specific makefiles.

9a5a3e8e74 Fix <math.h> to quieten most of our warnings.
I've reported the wcsftime bug upstream, but we really just want to use -D
to ensure the buggy code isn't built. (I've also brought our strftime a bit
closer to upstream now we have the right define.)

I don't think upstream is likely to fix all their sign-compare and
uninitialized warnings, so let's just silence them.

As for libm, again upstream isn't likely to fix all their warnings, and
silencing those made the ones that were our fault stand out. I've fixed
our <math.h> to fix the warnings caused by our lack of definitions for
the non-imprecise long-double functions. I checked the C99 standard, and
all these functions are there.
