The code to calculate thread stack and signal stack looks weird:
the thread stack size and signal stack size are related with
each other on 32-bit mode, but not on 64-bit mode. So change the
code to make the logic more resonable. This doesn't change anything
as we have defined SIGSTKSZ to 16K on arm64.

tests: allow brk to fail with ENOMEM
Any caller of brk needs to handle failure by falling back to mmap as
there's no guarantee that other mappings are not placed above the brk
heap. Since jemalloc starts with mmap in the first place and dlmalloc
knows how to fall back to mmap, it's already a legacy API in Android.
Forcing it to succeed rules out stronger ASLR implementations where the
brk heap might not have any room to grow. It's also valid for the brk
implementation to simply return -1 with errno set to ENOMEM in every
case and that's a good way of finding anything relying on it. It would
make sense for it to be an optional kernel feature.
The brk heap is also not guaranteed to be initially page aligned. PaX
ASLR randomizes the internal bits. It was only mentioned in a comment to
explain the design of the test though.

Fix the stack-protector test for x86/x86-64.
Built for fugu this was working fine, but built for generic x86/x86-64
the compiler was (a) optimizing out all the stack writes and (b) inserting
enough padding on x86-64 for the canary to be safely out of the way.
While here, let's tighten up this test so we test that it's sufficient to
only overwrite the buffer by one byte...

clock_nanosleep: add CLOCK_THREAD_CPUTIME_ID special case
POSIX makes "the CPU-time clock of the calling thread" (i.e.,
CLOCK_THREAD_CPUTIME_ID) a special case which returns EINVAL instead of
ENOTSUP.
However, the clock_nanosleep syscall treats this clock just like any
other, and returns -EOPNOTSUPP to indicate an unimplemented nanosleep
handler. So we need to handle this ourselves in userspace.
This change fixes the LTP clock_nanosleep01 testcase.

from uname(2).

clone: check for NULL child stack
The clone syscall accepts NULL child stacks, interpreting this to mean
the child gets a copy of the parent's stack with copy-on-write
semantics. However clone(2) is explicitly documented to treat this an
an error.
"Fortunately" every architecture's __bionic_clone implementation pushes
something onto the child stack before making the clone syscall. So we
know fixing this won't break legacy apps, because any app that tried
using a NULL child stack would have died with SIGSEGV.
This change fixes the LTP clone04 testcase.
