Fix corner cases of ipc syscall decoding * xlat/ipccalls.in: New file. * ipc.c: New file. * Makefile.am (libstrace_a_SOURCES): Add it. * linux/dummy.h (sys_ipc): Remove stub alias. * syscall.c (decode_ipc_subcall): Treat 1st argument of ipc syscall as "unsigned int". [S390 || S390X]: Skip ipc cubcalls that have non-zero version. [SPARC64]: Likewise, for the native personality. Save ipc cubcall version for later use by specific ipc parsers. * ipc_msg.c (SYS_FUNC(msgrcv)): Handle non-zero ipc subcall version. [SPARC64]: Handle non-ipc_kludge case for the native personality. * linux/subcall.h (msgrcv): Change nargs from 4 to 5. * linux/s390/syscallent.h (ipc): Change nargs from 6 to 5. * linux/s390x/syscallent.h (ipc): Likewise.

Automatically replace PRI_kr[dux] with PRI_kl[dux] Remove temporary macros created for transition from long to kernel_ulong_t. Automatically replace PRI_kr[dux] with PRI_kl[dux] using $ git grep -l 'PRI_kr[dux]' | xargs sed -ri 's/PRI_kr([dux])/PRI_kl\1/g' * defs.h (PRI_krd, PRI_kru, PRI_krx): Remove. All users updated.
