Introduce 2 new flags in types.h: * __HAVE_SYSCALL_INTERN. If this is defined, e_syscall is replaced by e_syscall_intern, which is called at key places in the kernel. This can be used to set a MD syscall handler pointer. This obsoletes and replaces the *_HAS_SEPARATED_SYSCALL flags. * __HAVE_MINIMAL_EMUL. If this is defined, certain (deprecated) elements in struct emul are omitted.

restructure struct emul and execsw, in preparation to make emulations LKMable: * move all exec-type specific information from struct emul to execsw[] and provide single struct emul per emulation * elf: - kern/exec_elf32.c:probe_funcs[] is gone, execsw[] how has one entry per emulation and contains pointer to respective probe function - interp is allocated via MALLOC() rather than on stack - elf_args structure is allocated via MALLOC() rather than malloc() * ecoff: the per-emulation hooks moved from alpha and mips specific code to OSF1 and Ultrix compat code as appropriate, execsw[] has one entry per emulation supporting ecoff with appropriate probe function * the makecmds/probe functions don't set emulation, pointer to emulation is part of appropriate execsw[] entry * constify couple of structures

Make the setregs hook emulation-specific, rather than executable format specific. Struct emul has a e_setregs hook back, which points to emulation-specific setregs function. es_setregs of struct execsw now only points to optional executable-specific setup function (this is only used for ECOFF).
