Summary:
The pthread_once(3)/NetBSD type is built with the following structure:
struct __pthread_once_st {
pthread_mutex_t pto_mutex;
int pto_done;
};
Set the pto_done position as shifted by __sanitizer::pthread_mutex_t_sz
from the beginning of the pthread_once struct.
This corrects deadlocks when the pthread_once(3) function
is used.

Cast SIG_IGN to (uptr).
SIG_IGN is defined on NetBSD as a function pointer and cannot be
assigned to an integer as it is.

Summary:
Changes:
* Add initial msan stub support.
* Handle NetBSD specific pthread_setname_np(3).
* NetBSD supports __attribute__((tls_model("initial-exec"))),
define it in SANITIZER_TLS_INITIAL_EXEC_ATTRIBUTE.
* Add ReExec() specific bits for NetBSD.
* Simplify code and add syscall64 and syscall_ptr for !NetBSD.
* Correct bunch of syscall wrappers for NetBSD.
* Disable test/tsan/map32bit on NetBSD as not applicable.
* Port test/tsan/strerror_r to a POSIX-compliant OSes.
* Disable __libc_stack_end on NetBSD.
* Disable ReadNullSepFileToArray() on NetBSD.
* Define struct_ElfW_Phdr_sz, detected missing symbol by msan.
* Change type of __sanitizer_FILE from void to char. This helps
to reuse this type as an array. Long term it will be properly
implemented along with SANITIZER_HAS_STRUCT_FILE setting to 1.
* Add initial NetBSD support in lib/tsan/go/buildgo.sh.
* Correct referencing stdout and stderr in tsan_interceptors.cc
on NetBSD.
* Document NetBSD x86_64 specific virtual memory layout in
tsan_platform.h.
* Port tests/rtl/tsan_test_util_posix.cc to NetBSD.
* Enable NetBSD tests in test/msan/lit.cfg.
* Enable NetBSD tests in test/tsan/lit.cfg.
