This declares an API for libsys which currently consists of
sys_<foo>() declarations for system call stubs and function pointer
typedefs of the form sys_<foo>_t. The vast majority of the
implementation resides in a generated _libsys.h which ensures that all
system call stub declarations match syscalls.master.

| 67 | Does __BEGIN_DECLS provide enough force to make compiler attach the right call ABI to the typedef'ed function types? | |

|---|---|---|
| 67 | My thought was that it prevents them from being name mangled in C++, but even there I'm not sure it matters on any architecture we care about? Maybe there would otherwise be an edge case where type promotion differences were an issue. It might be we don't need this around the typedefs. | |

| 67 | We didn't need that before, when typedefs were used only internally by libc. Now since they are exposed, it is more subtle. | |
