b410d0e69e Implement __gnu_[u]ldivmod_helper methods in libc
These symbols were previously provided by Android's out-dated libgcc,
but they're removed/deprecated in upstream libgcc, and also won't be
available in libclang_rt.builtins. We need to provide these methods in
libc itself for compatiblity.

Test: build with these symbols stripped in libgcc

915c5fb9f6 libdl.a: make dlerror() always report an error.
Seems only logical, given that all the other calls fail.

(Only thing that's weird about this is that calling dlerror() usually
clears the error until you do something else that causes an error, but
that doesn't seem worth the bookkeeping?)

390be50067 Workaround ASan not knowing about reallocarray.
Ensure we call realloc@plt rather than (as was previously happening)
inlining realloc into reallocarray, which makes the allocation invisible
to ASan.

aca110173f Comment about lock destruction and unlocking
Add a couple of comments explaining that a mutex can be freed during
the unlock call, immediately after the unlock's atomic exchange call but
before its futex wakeup call.

4b6c0f5dce PIMutexUnlock: load owner_tid in non-common case
For a recursive or errorcheck PI mutex, the old_owner variable wasn't
being initialized. As a result, unlocking a doubly-locked recursive
mutex owned by another thread decremented the mutex counter. Instead, the
unlock call should fail with EPERM.

584bc626b6 Move libdl and linker to static NOTICE files.
The libstdc++ directory has no copyright headers, so it was a no-op
anyway.

The interesting part will be switching libc and libm over to genrules...

int*.

d67b03734d libc: generate syscall stubs in one big file...
...all the better to switch to a genrule rather than checking in
generated source.

This also removes all the code in the script to deal with git,
rather than fix it. We won't need that where we're going.
