[libcxx] Enable noexcept for GCC 4.6 and greater
Summary:
This patch allows GCC 4.6 and above to use `noexcept` as opposed to
`throw()`.
Is it an ABI safe change to suddenly switch on `noexcept`? I imagine
it must be because it's disabled in w/ clang in C++03 but not C++11.

This should fix errors from gcc 4.6 and higher when compiling llvm-cov

with libc++, which is also C++11. Also change one _Static_assert (which
is really C11) back into static_assert, like upstream.
This should help when compiling libcxxrt with newer versions of gcc,
which refuse to recognize any form of static assertions, if not
compiling for C++11 or higher.
While here, add -nostdinc++ to CFLAGS, to prevent picking up any C++
headers outside the source tree.
[X86] Emit a proper ADJCALLSTACKDOWN in EmitLoweredTLSAddr
We forgot to add the second machine operand to our ADJCALLSTACKDOWN,
resulting in crashes in PEI.
This fixes PR27071.
This should fix an assertion failure during buildworld, when using -Os,
and targeting either i386 directly, or building the 32-bit libraries on
amd64.

Add <atomic> to ThreadPool.h, since std::atomic is used
Summary:
Apparently, when compiling with gcc 5.3.2 for powerpc64, the order of
headers is such that it gets an error about std::atomic<> use in
ThreadPool.h, since this header is not included explicitly. See also:
https://llvm.org/bugs/show_bug.cgi?id=27058
Fix this by including <atomic>. Patch by Bryan Drewery.

Merge ELF Tool Chain r3434:
Previously, elfcopy defines:
VMA: section virtual address
LMA: PHDR(p_vaddr)
While binutils(libbfd) defines:
VMA: section virtual address and PHDR(p_vaddr).
LMA: PHDR(p_paddr)
For elfcopy, p_paddr is considered not meaningful and is always set
to the same value as p_vaddr.
elfcopy was implemented that way because I thought p_paddr is not
used/meaningful according to the ELF ABI. However it turned out
p_paddr is at least used in some ELF files, e.g. the FreeBSD kernel.
This change made elfcopy treat p_paddr as LMA, same as libbfd.
(However, some VMA/LMA related command line option still need tweaking
to make them compatible with binutils objcopy. This will be improved
later)
Ticket: #524
And typo fixes in r3435 and r3436.
This fixes the Xen kernel build.

Archive member handling works again
meta mode, treat missing reads as for writes.
Update dirdeps.mk - much improved startup time.
Update meta.stage.mk - avoid ln when chmod required.
struct tcpstat, because the structure can be zeroed out by netstat(1) -z,
and of course running connection counts shouldn't be touched.
Place running connection counts into separate array, and provide
separate read-only sysctl oid for it.
ftruncate/11, open/20, and truncate/11 copy sleep(1) to a temporary file on the
target filesystem, execute the binary, then expect a result. This doesn't work
with scenarios where the target binary cannot be executed, e.g. the filesystem
was mounted with -o noexec.
Ensure the filesystem hasn't been mounted with -o noexec for the testcases
before executing them.

Fix GCC atomic implementation in C++03

Detect relaxed constexpr rules for gcc versions
Pull in r255585 from upstream libc++ trunk (by Eric Fiselier):
Fix various GCC mis-configurations for newer versions.
This patch goes through and enables C++11 and C++14 features for newer GCC's.
The main changes are:
1. Turn on variable templates. (Uses __cpp_variable_templates)
2. Assert atomic<Tp> is trivially copyable (Uses _GNUC_VER >= 501).
3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)
4. XFAIL void_t test for GCC 5.1 and 5.2. Fixed in GCC 6.
Together, these should fix building clang 3.8.0 as part of building
world with recent versions of gcc (e.g. the devel/*-xtoolchain-gcc
ports).
Fix most GCC warnings during build. Only -Wattribute left.
This helps to fix a number of -Werror warnings when building world with
recent versions of gcc (e.g. the devel/*-xtoolchain-gcc ports).
The only relevant change here is the support for IPv6 in the config
file. The previous version of this supported IPv6 but not in the
config. The change for that ended up removing __sdp_sockaddr_to_sdp
which the IPV4 config code required; the IPv6 fix resolved the lack of
that symbol.
Note that the ChangeLog was lacking entries for which we already had the
changes for, which itself was an upstream bug.

An empty debug link target previously returned a confusing and incorrect
error like "objcopy: fread failed: No error: 0". Now, return an explicit
error.
GNU objcopy allows an empty file as the debug link target. However,
that case is nonsensical so diverging from GNU behaviour is fine.

Add weak-->strong symbol binding for

{__malloc_stats_print,__mallctl,__mallctlnametomib,__mallctlbymib}. These
bindings complete the set necessary to allow applications to replace all

Update openresolve to version 3.7.3 including:
* Save the initial working directory and change to it just before
running any scripts.
This avoids scripts putting files accidently where they shouldn't.
* Strip trailing dot from search and domain names.
* man page improvements.

After calling the cap_init(3) function Casper will fork from it's original
process, using pdfork(2). Forking from a process has a lot of advantages:
1. We have the same cwd as the original process.
2. The same uid, gid and groups.
3. The same MAC labels.
4. The same descriptor table.
5. The same routing table.
6. The same umask.
7. The same cpuset(1).
From now services are also in form of libraries.
We also removed libcapsicum at all and converts existing program using Casper
to new architecture.
