[PATCH 0/4] Change 'len' of to_xfer_partial to ULONGEST

[Yao Qi <yao@codesourcery.com>]

Hi,
This patch series is a preparation for the changes mentioned in the
discussion on changing target_ops method to_xfer_partial [1], in which,
the expected change would be

    LONGEST (*to_xfer_partial) (struct target_ops *ops,
				enum target_object object, const char *annex,
				gdb_byte *readbuf, const gdb_byte *writebuf,
				ULONGEST offset, LONGEST len);

to

    enum target_xfer_status (*to_xfer_partial) (struct target_ops *ops,
				enum target_object object, const char *annex,
				gdb_byte *readbuf, const gdb_byte *writebuf,
				ULONGEST offset, ULONGEST len, ULONGEST *xfered_len);

I started from the 'len' "LONGEST -> ULONGEST" transition, and that
is what this patch series tries to do.  This change is quite mechanical.
Regression tested on x86_64-linux with both native and gdbserver.  I
also rebuilt GDB in the following ways:

 - on x86-linux, with all targets enabled,
 - cross build native mingw32,mips-linux,hurd,sparc-linux, gdb on
   linux,
 - build native powerpc-linux gdb on gcc110
 - build spu-elf target on gcc110
 - build aix native gdb on gcc111
 - build native gdb for netbsd on gcc70

There are still some native targets uncovered, such as darwin, but it
should be easy to fix the build error.  Patch 2 is major part of this
series.  Patch 3 adjusts linux_common_xfer_osdata and patch 4 adjusts
two gdbarch methods.

I tried to turn -Wconversion on to help me to check some signed/unsigned
conversion, but it gives me thousands of errors in a clean build
(without my patches.  Looks signed/unsigned types are used freely in GDB
code base, so I didn't take much care of signed/unsigned conversion.

I'll finish the interface to_xfer_partial change in next step, and
adjust its implementations on some targets, such as tfile and ctf
targets.
