* convex-xdep.c, hppab-nat.c, i860-tdep.c, infptrace.c: Remove

decl for attach_flag, it now lives in inferior.h.
* hppa-pinsn.c:  Reformat opcode tables.  Add function prototypes.
Make most functions static.
* hppah-nat.c:  General cleanups, remove BSD specific code (since
that all lives in hppab-nat.c).
* hppah-tdep.c (frame_chain_valid), tm-hppa.h (FRAME_CHAIN):
Change sense of test against inside_entry_file().  This fix is
from U. of Utah.
* tm-hppa.h (PUSH_DUMMY_FRAME, POP_FRAME):  Use char * for 2nd arg
to read/write_register_bytes().
