pid_t is 64-bit in 64-bit mingw, but the windows process/thread
functions return a DWORD(uint32_t). Instead of promoting to a pid_t and
fixing the format strings, just use a uint32_t to store the values.
android_thread_id also cannot be a 64-bit pointer, so for windows just
force it to be a uint32_t.
libutils/ProcessCallStack only works under Linux, since it makes heavy
use of /proc. Don't compile it under Windows or Darwin.

It's easier for people to debug, and side-steps the problem that errno
values differ between architectures.

There's an inherent race in trying to read out the thread name from
the system and the thread closing out on its own (and thus being removed
from procfs).
Try to handle this by formatting the thread name unconditionally with
the tid when getting the thread name fails (instead of dereferencing
NULL and crashing).
