* gregset.h: New file. Typedefs for gdb_gregset_t and
gdb_fpregset_t, prototypes for supply_gregset and friends.
* procfs.c: Include gregset.h. Delete local prototypes for
supply_gregset etc., and local typedef gdb_gregset_t etc.
* sol-thread.c: Include gregset.h, delete local prototypes,
add appropriate casts to gdb_gregset_t.
* uw-thread.c, lin-thread.c, core-sol2.c, core-regset.c,
sparc-tdep.c, ptx4-nat.c, ppc-linux-nat.c, mipsv4-nat.c,
m88k-nat.c, m68klinux-nat.c, m68k-tdep.c, irix5-nat.c,
irix4-nat.c, ia64-linux-nat.c, i386v4-nat.c, cxux-nat.c,
arm-linux-nat.c, alpha-nat.c: Include gregset.h.
* config/nm-linux.h: Define GDB_GREGSET_T, GDB_FPREGET_T.
* config/sparc/tm-sun4sol2.h: Ditto.

i386_linux_sigtramp_saved_sp): Deleted. Folks rightly pointed
out that these are target-dependent, and useful in non-native
configurations. Moved to...
* i386-linux-tdep.c: ... Here, a new file.
* Makefile.in (ALLDEPFILES): Add i386-linux-tdep.c.
(i386-linux-tdep.o): New rule.
(i386-linux-nat.o): We no longer depend on frame.h.
* config/i386/linux.mt (TDEPFILES): Add i386-linux-tdep.o.

i386_linux_sigtramp_saved_sp): Deleted. These all implement
Linux-specific signal trampoline detection, and should be moved to...
* i386-linux-nat.c: ... here.
* config/i386/tm-linux.h (I386_LINUX_SIGTRAMP): No need to define
this any more, since we're not enabling OS-specific code in a
OS-independent file.
Allow GDB to run on Linux 2.0 again.
* config.in: Add HAVE_PTRACE_GETREGS.
* configure.in: Check if <sys/ptrace.h> defines PTRACE_GETREGS.
* configure: Regenerated.
* config/i386/nm-linux.h (CANNOT_FETCH_REGISTER,
CANNOT_STORE_REGISTER): New defines.
* i386-linux-nat.c (have_ptrace_getregs): New variable.
(PTRACE_XFER_TYPE, CANNOT_FETCH_REGISTER, fetch_register,
old_fetch_inferior_registers, CANNOT_STORE_REGISTER,
store_register, old_store_inferior_registers): Copied over from
`inptrace.c' as a temporary measure.
(fetch_regs, store_regs, fetch_fpregs, store_fpregs):
Conditionalize on HAVE_PTRACE_GETREGS. Define stubs if
HAVE_PTRACE_GETREGS isn't defined.
(fetch_regs): Reset `have_ptrace_getregs' if ptrace call fails
with EIO.
(fetch_inferior_registers, store_inferior_registers): Fall back on
the method use in `infptrace.c' (by calling
old_fetch_inferior_registers and old_store_inferior_registers) if
`have_ptrace_getregs' isn't set.
* i386-linux-nat.c: Use elf_gregset_t and elf_fpregset_t instead
of gregset_t and fpregset_t. Those are the only names that are
guaranteed to specify the right types for all supported Linux
systems out there.
Various doc fixes and gratitious local variable renames, all in an
attempt to stress similarities between the code and unify the
terminology used. Use ISO-C all over.
(regmap): Remove trailing comma.
(FPREG_ADDR): Renamed from FPREGSET_T_FPREG_ADDR.
(convert_to_gregset): Make static. Remove GDB_REGS argument. It
is unnecessary and wasn't used anyway. All callers changed.
(convert_to_fpregset, convert_to_xfpregset): Likewise.
(fetch_regs, store_regs): Remove unused variable `regno'.
(fill_fpregs): If REGNO is not -1, only update the specified
register.
(fetch_core_registers): Renamed from
i386_linux_fetch_core_registers. There is no need for a unique
name since the function is static anyway.
(linux_elf_core_fns): Renamed from i386_linux_nat_core_functions
since it is more descriptive.
