System calls are now part of dedicated symbol library

- This symbol library is still special in that symbols are created on
  demand and never actually added.  It just serves as a link to
  protolibrary with system call prototypes, and has a name (SYS).

- Prototypes for system calls were moved to a dedicated prototype
  library called syscalls.conf.

- Because it's undesirable to look up syscall prototypes in anything
  but the dedicated syscall protolib, prototype.c/.h now understand
  that some lookups shouldn't be done recursively (and so we never
  pick the definition from -F file that just happens to have the same
  name as a system call).  The good thing is that now libraries can
  actually use symbols named SYS_something without clashing with
  system call prototypes.

- One test case needed to be updated, because we now display system
  calls as something@SYS instead of SYS_something.
