Let g_thread_list_lock only protect g_thread_list. As glibc/netbsd don't protect access to thread struct members by a global lock, we don't want to do it either. This change reduces the responsibility of g_thread_list_lock to only protect g_thread_list. Bug: 19636317 Change-Id: I897890710653dac165d8fa4452c7ecf74abdbf2b

<pthread.h> fixes and pthread cleanup. <pthread.h> was missing nonnull attributes, noreturn on pthread_exit, and had incorrect cv qualifiers for several standard functions. I've also marked the non-standard stuff (where I count glibc rather than POSIX as "standard") so we can revisit this cruft for LP64 and try to ensure we're compatible with glibc. I've also broken out the pthread_cond* functions into a new file. I've made the remaining pthread files (plus ptrace) part of the bionic code and fixed all the warnings. I've added a few more smoke tests for chunks of untested pthread functionality. We no longer need the libc_static_common_src_files hack for any of the pthread implementation because we long since stripped out the rest of the armv5 support, and this hack was just to ensure that __get_tls in libc.a went via the kernel if necessary. This patch also finishes the job of breaking up the pthread.c monolith, and adds a handful of new tests. Change-Id: Idc0ae7f5d8aa65989598acd4c01a874fe21582c7

Fix x86_64 build, clean up intermediate libraries. The x86_64 build was failing because clone.S had a call to __thread_entry which was being added to a different intermediate .a on the way to making libc.so, and the linker couldn't guarantee statically that such a relocation would be possible. ld: error: out/target/product/generic_x86_64/obj/STATIC_LIBRARIES/libc_common_intermediates/libc_common.a(clone.o): requires dynamic R_X86_64_PC32 reloc against '__thread_entry' which may overflow at runtime; recompile with -fPIC This patch addresses that by ensuring that the caller and callee end up in the same intermediate .a. While I'm here, I've tried to clean up some of the mess that led to this situation too. In particular, this removes libc/private/ from the default include path (except for the DNS code), and splits out the DNS code into its own library (since it's a weird special case of upstream NetBSD code that's diverged so heavily it's unlikely ever to get back in sync). There's more cleanup of the DNS situation possible, but this is definitely a step in the right direction, and it's more than enough to get x86_64 building cleanly.

Fix pthreads functions that should return ESRCH. imgtec pointed out that pthread_kill(3) was broken, but most of the other functions that ought to return ESRCH for invalid/exited threads were equally broken. Change-Id: I96347f6195549aee0c72dc39063e6c5d06d2e01f
