Allocate thread local buffers in __init_tls.
Thread local buffers were using pthread_setspecific for storage with
lazy initialization. pthread_setspecific shares TLS slots between the
linker and libc.so, so thread local buffers being initialized in a
different order between libc.so and the linker meant that bad things
would happen (manifesting as snprintf not working because the
locale was mangled)
Bug: http://b/20464031
Test: /data/nativetest64/bionic-unit-tests/bionic-unit-tests
everything passes
Test: /data/nativetest/bionic-unit-tests/bionic-unit-tests
thread_local tests are failing both before and after (KUSER_HELPERS?)
Test: /data/nativetest64/bionic-unit-tests-static/bionic-unit-tests-static
no additional failures
