There's still <cutils/atomic.h> in a test, but I don't understand why
that isn't just std::atomic.
Also add a shared tgkill wrapper to libbase.

MinGW uses gnu_printf to force C99 printf analysis with GCC, but clang
does not support gnu_printf. So just use the default that's used for
other platforms. This also mirrors upstream commit
015e637b4b/.

This change lets android::base::ScopeGuard be useful in STL containers
(e.g. std::vector<android::base::ScopeGuard<std::function<void()>>>). It
also provides perfect forwarding for android::base::make_scope_guard.

In most reasonable cases, this is actually a bug. So delete the

Some tests may create a File* by calling fdopen() on the temp file's
fd. We should release the ownership of fd in this case to avoid the
double close.

Clang's assert_capability and assert_shared_capability annotations are
nonfunctional until https://reviews.llvm.org/rL309725 is relanded and
makes its way into our toolchain. Work around this by using the
equivalent assert_lock and assert_shared_lock.

The use of ReadAtOffset is meant to allow concurrent access
to the zip archive once it has been loaded. There were places
where this was the case, and some places that did a seek + read
combination, which could lead to data races.
NOTE: On Windows, we are not using pread as the implementation of
ReadAtOffset, therefore the guarantees on Windows are weaker.
On Linux, pread allows the file descriptor to be read at a specific
offset without changing the read pointer. This allows inherited fd's
and duped fds to be read concurrently.
On Windows, we use the ReadFile API, which allows for an atomic seek +
read operation, but modifies the read pointer. This means that any mix
use of ReadAtOffset and Read will have races. Just using ReadAtOffset is
safe.
For the Windows case, this is fine as the libziparchive code now only
uses ReadAtOffset.

::android::base::GetMinimumLogSeverity() is defined externally, so the
static analyzer was allowed to assume that we continue executing after a
LOG(FATAL).
I manually audited all of the code I have access to, and the only
"change the minimum log severity" statements I can see keep FATAL
enabled (...and continuing after a FATAL is highly sketchy to me
anyway).
(I'm sure I tested this at some point in making the previous patch. I
probably broke it in a refactor before sending it out for review; my
bad. :) )
Bug: None
Test: m without the static-analyzer builds; m with it yields fewer
false positives.

This helps us have less false-positives.
We do this instead of `#undef NDEBUG`, since undefing NDEBUG actually
gave us more false-positives (...and build breakages) than simply
leaving it defined.
Bug: None
Test: Ran the static analyzer across internal master. 213 fewer warnings
(15 Medium, 2 Low, the remainder are 'Analyzer'). All of the dropped
warnings I audited were false-positives. It adds ~3 Tidy warnings.
