we shouldn't bugger off to userland when there still are
pending signals; among other things it makes e.g. SIGSEGV
triggered by failure to build a sigframe to be delivered
_now_ and not when we hit the next syscall or interrupt.

Break up syscall_trace() into separate entry and exit routines that use
tracehook_report_syscall_entry() and tracehook_report_syscall_exit().

In m68k/m68knommu assembly files, the same value is called sometimes
PT_OFF_VECTOR, but more frequently PT_OFF_FORMATVEC.  Standardize
name to PT_OFF_FORMATVEC.

strace enabled is marked using the `flags' field of the `thread_info' struct.
68360 version of entry.S did test a wrong bit in a wrong structure
(task_struct).

68328 version of entry.S did test the right bit in the right structure,
but wrongly, because the `flags' field is 32 bit wide, while the used
assembler insn (btst) only accesses a 8 bit byte in memory.

Fix both using code already used in the coldfire version of entry.S

Commit f159ee78 ("locking,
m68k/asm-offsets: Rename pt_regs offset defines") breaks the
m68knommu entry code that relies on these define names.
Fix the files to match the new define names.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
