System calls: simple stubs

[mrsmkl]

The following system calls just need simple stubs. They could be handled using the generic system calls, but it will be more efficient to add stubs. 29. Pause:nothing to implement 34. Nice: nothing to implement 35. Sync: nothing to implement 42. Pipe: nothing to implement 51. Acct: nothing to implement, but what is it? 66. Setsid: nothing to implement 75. Setrlimit: nothing to implement 96. Getpriority: nothing to implement 97. Setpriority: nothing to implement 104. Setitimer: nothing to implement 114. Wait4: nothing to implement 118. Fsync: nothing to implement? 121. setdomainname: nothing to implement 125. Mprotect: nothing to implement 148. Fdatasync: Nothing 150. Mlock: nothing 151. Munlock: nothing 152. Mlockall: nothing 153. Munlockall: nothing 163. Mremap: nothing 199, 200, 201, 202: getuid32, getgid32, geteuid32, getgid32: nothing 203, 204, 213, 214. Setreuid32, setregid32, setuid32, getuid32: nothing 218. Mincore: nothing 219. Madvise: nothing 265. Clock_nanosleep: nothing 272. Fadvise64: nothing 299. Futimesat: nothing 303. Linkat: nothing 308. Pselect: nothing 331. Pipe2: nothing

how do you want them stubbed?

[mrsmkl]

So that they work like in https://github.com/kripken/emscripten/blob/master/src/library_syscall.js Mostly this means that they will just return some constant value.
