This is a copy of a few libunwind headers from https://android.googlesource.com/platform/external/libunwind
We can't make the repo a git submodule because it contains a folder called 'aux' which
is reserved on Windows and would break on checkout there.
These files are unmodified from the originals and should preferably stay that
way to avoid merge hell.

/* This file defines the runtime-support routines for dynamically
generated code. Even though it is implemented as part of libunwind,
it is logically separate from the interface to perform the actual
unwinding. In particular, this interface is always used in the
context of the unwind target, whereas the rest of the unwind API is
used in context of the process that is doing the unwind (which may be
a debugger running on another machine, for example).
Note that the data-structures declared here server a dual purpose:
when a program registers a dynamically generated procedure, it uses
these structures directly. On the other hand, with remote-unwinding,
the data-structures are read from the remote process's memory and
translated into internalized versions. To facilitate remote-access,
the following rules should be followed in declaring these structures:
(1) Declare a member as a pointer only if the the information the
member points to needs to be internalized as well (e.g., a
string representing a procedure name should be declared as
"const char *", but the instruction pointer should be declared
as unw_word_t).
(2) Provide sufficient padding to ensure that no implicit padding
will be needed on any of the supported target architectures. For
the time being, padding data structures with the assumption that
sizeof (unw_word_t) == 8 should be sufficient. (Note: it's not
impossible to internalize structures with internal padding, but
it does make the process a bit harder).
(3) Don't declare members that contain bitfields or floating-point
values.
(4) Don't declare members with enumeration types. Declare them as
int32_t instead. */
