042db0bd0f cmake: cleanup logic that sets flags per target/subdir
The previous logic that used a COMMON_*_FLAGS intermediate variable
and then re-assigned CMAKE_*_FLAGS before including each subdirectory
was confusing and ugly. This PR is the right way to do it.

This commit is purely refactoring: built binaries unchanged.

0f990d0183 cmake,common: flag for stack trace
By default the flag is enabled whenever libunwind is found on the
system, with the exception of static build on OSX (for which we can't
install the throw hook #932 due to lack of support for --wrap in OSX
ld64 linker).

4b3a7885ac cmake: install throw hook in OSX build too
This is an attempt to fix build with STATIC=ON on OSX (#932):

[ 95%] Linking CXX executable ../../bin/bitmonerod Undefined symbols for
architecture x86_64: "___real___cxa_throw", referenced from:
___wrap___cxa_throw in libcommon.a(stack_trace.cpp.o) ld: symbol(s) not found

3c92c2f096 cmake: do not install hook on throw when building tests
This fixes build of tests with STATIC=ON, which failed with:

/tmp/cc8lNtqY.ltrans12.ltrans.o: In function
`boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::thread_resource_error>
>::rethrow() const [clone .lto_priv.41]':
cc8lNtqY.ltrans12.o:(.text+0x4e): undefined reference to `__wrap___cxa_throw'

The hook is implemented in libcommon, which is not linked into some of the test
binaries.  An alternative solution is to link all tests against libcommon,
but that seems worse because it introduces a false dependency (also,
I tried that and for some of the test binaries the linker still failed to
pick up the symol from libcommon, strangely.)

dca9fe175c cmake: do not pass -Werror when building tests
The tests currently issue a warning that
"warning: -fassociative-math disabled; other options take precedence"

The associative math optimization is turned on indirectly by -Ofast.
Apparently, the optimization is forced to be disabled, while compiling
test harnesses generated by Google Test framework.

Unfortunately, there is no -Wno-error=* flag to disable this warning
(see gcc --help=warnings).

An alternative to this patch is to disable the optimization explicitly
with -fno-associative-math, but that seems worse.

Another alternative is to not pass -Ofast for tests build, but we
want the tests to be built with exact same optimization flags as
the code being tested, otherwise the value of the tests is diminished.

Another alternative is to remove -Werror from the entire build, but
it's good to include that flag to preclude people leaving warnings.

A note regarding implementation of not passing -Werror for tests:
I considered filtering out -Werror from CMAKE_{C,CXX}_FLAGS but
that seems to be worse because it's surprizing behavior, to those
reading the code that adds -Werror. It is better to add it for
when it is used and not added otherwise. I also considered relying
on order, adding -Werror after inluding 'tests' subdir, but before
including the other subdirs, but that also seems cryptic to the
reader. So, I settled with the current solution, of explicitly
setting CMAKE_{C,CXX}_FLAGS to different values before including the
respective subdir.

Testing done: compared compiler invocation for non-tests source files
using `make VERBOSE=1` with and without this commit: the only difference
is the position of -Werror. So, this commit doesn't change the binary.

19349d7870 cmake: ARM: clang: make warning non-fatal: inline asm

f3e09f36d3 cmake: link with -latomic for clang
otherwise clang build fails with

../cryptonote_core/libcryptonote_core.a(miner.cpp.o): In function
`std::__atomic_base<unsigned long long>::load(std::memory_order) const':
/usr/bin/../lib/gcc/i686-pc-linux-gnu/6.1.1/../../../../include/c++/6.1.1/bits/atomic_base.h:396:
undefined reference to `__atomic_load_8'

This has no effect on the gcc build.

The one strange thing is that test code like

std::atomic<int> x;
int main() { return x; }

compiles and links without errors with clang, without -latomic.  This
alone would suggest that this patch is unnecessary, but that is not the
case. It's not clear exactly why, though. The bitmonero code is
including the same header, but it must be doing something more complex
than in this test code snippet that causes the failure at link time
pasted above. In any case, passing -latomic fixes the problem and
seems safe.

f4b35aeafd cmake: include -ldl via cmake built-in var
This does two things:
1. fixes clang build, which otherwise errors with undefined symbol
'dlsym'.
2. simplifies the cmake script, delegating to cmake to figure
   out platform-specific flags for linking against the dl library.

4dce26bba4 cmake: do not pass -stdlib=c++ to clang >=3.7
Tested on Linux (Arch) with clang 3.7 and 3.8 i686 and ARM:
if -stdlib=c++ is passed to clang, then the build errors
out with <string>,<iostrea>,etc. headers not found. Simply
not passing the arg fixes the problem.

**NOTE**: not tested on OSX.

1e89f4f2c5 cmake: do not ignore dangerous warnings with -Wno-error
Shorten the list of warnings that are reported, but
which are forced to NOT generate an error, via -Wno-error.

Unwhitelist these: strict-aliasing, sign-compare, type-limits

For example, ignoring strict-aliasing warning caused
lots of wasted time diagnosing Issue #847.

remove POSIX_C_SOURCE and remove dlfcn.h for static builds
The former was a faulty "fix" for gmtime_r not existing on Windows. The latter is needed only for dynamic builds, and is not included with msys2, which ends up fine because Windows is only built static at this time.

cmake: Fix unbound config compile settings
This allows the OpenSSL function checks to compile in unbound's CMake
configuration.

Otherwise, the functions SHA256() and EVP_sha512() won't be called from
libunbound as possible algorithms.

They had not been compiling because static OpenSSL libraries were being
used, along with lack of -ldl. The static library preference is
unnecessary for the checks, so use default suffixes ordering for
CMAKE_FIND_LIBRARY_SUFFIXES when building unbound.
