libsys: various updates - move system calls for use by services from libminlib into libsys; - move srv_fork(2) and srv_kill(2) from RS and into libsys; - replace getprocnr(2) with sef_self(3); - rename previous getnprocnr(2) to getprocnr(2); - clean up getepinfo(2); - change all libsys calls that used _syscall to use _taskcall, so as to avoid going through errno to pass errors; this is already how most calls work anyway, and many of the calls previously using _syscall were already assumed to return the actual error; - initialize request messages to zero, for future compatibility (note that this does not include PCI calls, which are in need of a much bigger overhaul, nor kernel calls); - clean up more of dead DS code as a side effect.

Clean up interface to PM and VFS - introduce new call numbers, names, and field aliases; - initialize request messages to zero for all ABI calls; - format callnr.h in the same way as com.h; - redo call tables in both servers; - remove param.h namespace pollution in the servers; - make brk(2) go to VM directly, rather than through PM; - remove obsolete BRK, UTIME, and WAIT calls; - clean up path copying routine in VFS; - move remaining system calls from libminlib to libc; - correct some errno-related mistakes in libc routines.
