* gdbserver/Makefile.in: Add regformats directory to INCLUDE_CFLAGS,
and remove unused $(INCLUDE_DIR).
Add regcache.c to OBS.
Add generated register protocol files to clean target.
Update dependencies for new objects, obsolete old target code.
* gdbserver/linux-low.c: Remove all platform-specific code to
new files. Remove various dead code. Update to use regcache
functionality.
* gdbserver/remote-utils.c (fromhex): Add return statement
to quiet warning.
(putpkt): Dynamically allocate buf2 because PBUFSIZ is no longer
constant.
(input_interrupt): Add integer parameter to match prototype
of a signal handler.
(outreg): Use register_data ().
(prepare_resume_reply): Use gdbserver_expedite_regs.
* gdbserver/server.c (main): Dynamically allocate own_buf because
PBUFSIZ is no longer constant. Use registers_to_string () and
registers_from_string ().
* gdbserver/server.h: No longer include "defs.h". Add prototypes
for error (), fatal (), and warning (). Update definition of
PBUFSIZ to use regcache functionality. Add include guard.
* gdbserver/utils.c (fatal): Add missing ``const''.
(warning): New function.
* regformats/regdat.sh: Include "regcache.h" in generated files.
Provide init_registers () function.
* regformats/regdef.h: Add prototype for set_register_cache ().
Add include guard.
* gdbserver/linux-arm-low.c: New file.
* gdbserver/linux-i386-low.c: New file.
* gdbserver/linux-ia64-low.c: New file.
* gdbserver/linux-m68k-low.c: New file.
* gdbserver/linux-mips-low.c: New file.
* gdbserver/linux-ppc-low.c: New file.
* gdbserver/linux-sh-low.c: New file.
* gdbserver/regcache.c: New file.
* gdbserver/regcache.h: New file.
* gdbserver/low-linux.c: Removed obsolete file.
