This library is dynamically loaded and used by bionic, to replace selected
standard socket syscalls with versions that talk to netd.
Implement connect() by requesting that the socket be marked with the netId of
the default network and then calling through to the actual syscall.
There are two escape hatches:
+ If the fwmark server is unavailable, it isn't an error; we proceed with the
syscall. This might help at boot time (when the server isn't ready yet) and if
we get rid of the fwmarkd socket entirely in future platform versions.
+ If the ANDROID_NO_USE_FWMARK_CLIENT environment variable is set, we don't
attempt to use the fwmark server (even if it's available). This allows apps to
sidestep unforseen issues in production at runtime.

The BIO_CTRL_FLUSH function for files doesn't return anything useful
from the underlying fflush call, so it is safe to ignore this.

The declaration is useless and triggers a warning with clang 3.5 (in
code that's built with -Werror)

Forward declare ucontext_t so that it's not necessary for ucontext.h
to be included in the global header.

This new version doesn't require any specialized thread
implementation, it uses the Current implementation to do its job.
In addition, it runs much faster when multiple threads are trying
to unwind at the same time since the global signal lock is held for
only a small amount of time. Even running through the threads one at
a time should be faster since it no longer requires two passes through
the unwound stacks.
The new code now allows multiple simultaneous unwinds of the
same thread.
Finally, add the ability to unwind from a ucontext_t passed in. This
functionality doesn't work for remote unwinds yet.
