Instead of allocating the stack within a 16MB guard region as we
were doing before, just allocate the stack on its own. This isn't
as secure as with the guard region (since it means that an attacker
who can read the pthread_internal_t can determine the address of the
SCS), but it will at least allow us to discover more blockers until
a solution to b/118642754 is decided on.

Landing this change separately to the change that implements SCS
because it needs to land at the same time as an internal change. This
will simplify the situation in case SCS needs to be reverted again.

Adds libc_common_static and libc_common_shared targets. So that static
and shared objects can use different libraries.
In following changes I'll add dynamic dispatch code to
libc_common_shared.
Test: compile and run bionic unit test.

The signal stack is sufficiently large for a single invocation of the
signal handler, but in cases where the signal handler needs to recurse,
(e.g. if our address space is limited by RLIMIT_AS), it's too small for
us to get to the part where we recognize that we've recursed and bail
out.

This commit updates bionic versioner to use clang-r344140. To be
specific, this commit renames `clang::vfs::FileSystem` to
`llvm::vfs::FileSystem` and updates the headers.

* HWASan report invalid use of the allocator api (like alignment not
being power of two, or allocation size too large) in a way tests do not
expect.
* Code in .preinit_array runs before HWASan shadow is initialized and
needs to be excluded from instrumentation.
* It looks that mm system calls (mmap/mprotect/etc) will not allow
tagged pointers. In fact, the use of mprotect on malloc()ed memory is
doubtful - one can imagine some kind of speculative load from such
memory, as compiler knows that it is addressable.

According to posix, this test invokes undefined behavior by deleting
a timer twice.
According to hwasan, the second call to timer_delete loads
kernel_timer_id from previously deallocated PosixTimer (i.e.
heap-use-after-free).

This commit adds "include" (full path: "bionic/libc/include") to
exported_include_dirs for libc. Without this change,
header-abi-checker will strip all functions from ABI dumps.

Currently, getnameinfo() will never issue a reverse DNS lookup if the first
byte of the IPv6 address is 0x00. This means it is not possible to do a
reverse DNS lookup for a NAT64 address if the NAT64 prefix is the well-known
prefix. Make this possible by treating the well-known prefix specially. This
is not needed for unicast NAT64 prefixes because they do not start with 0x00.
