0dd7b52ede gdbserver/linux-low: delete 'linux_target_ops' and 'the_low_target' 
All the linux target ops have been moved into linux_process_target
as methods.  The 'linux_target_ops' struct and its instantiations
are now obsolete.  Delete them.

ef0478f611 gdbserver/linux-low: start turning linux target ops into methods 
This is the beginning of a series of patches that convert the linux
low targets into classes derived from linux_process_target.  At the
end of the series we obtain a class hierarchy that looks like this:

process_stratum_target
^
|
|-- linux_process_target
    ^
    |
    |-- x86_target (defined in linux-x86-low)
    |-- aarch64_target (defined in linux-aarch64-low)
    |-- ppc_target (defined in linux-ppc-low)
    |-- ...

In several cases, linux_process_target simply forwards a target op
request to a corresponding linux_target_ops function.  For these
cases, the definition in linux_process_target will be removed and the
definition will be left to the deriving linux low target class; using
inheritance provides a nice and natural, object-oriented
simplification in these cases.

The series converts linux_target_ops into protected methods of
linux_process_target one by one.  Throughout the series, based on the
needs, static functions defined in linux-low.cc are converted to
private methods of linux_process_target as well.  This is done either
as separate patches or as integrated into a patch that convert a
particular linux_target_op into a method.

The series ends with the patch titled "gdbserver/linux-low: delete
'linux_target_ops' and 'the_low_target'".

Built and regression-tested on x86_64-linux.  The following linux low
targets have been built (but not tested) via cross-compilation:
aarch64, arm, m68k, mips, ppc, riscv, s390, sh, sparc.  The other
targets (bfin, cris, crisv32, ia64, m32r, nios2, tic6x, tile, xtensa)
were neither built nor tested.

52405d85ec gdbserver: finish turning the target ops vector into a class 
Now that 'process_stratum_target' has a single field left, namely 'pt'
of type 'process_target', and that all the requests to a
'process_stratum_target' are forwarded to 'pt', meld the
'process_target' class into 'process_stratum_target'.

This essentially means

1. All the references of the form 'the_target->pt' become 'the_target'.

2. All the uses of the name 'process_target' become
   'process_stratum_target'.

3. The platform-specific target op vectors (e.g. linux_target_ops) are
   removed and instances of their "process target" classes are used
   instead.

feacfcacaa gdbserver: rename source files to .cc 
For the same reasons outlined in the previous patch, this patch renames
gdbserver source files to .cc.

I have moved the "-x c++" switch to only those rules that require it.

gdbserver/ChangeLog:

	* Makefile.in: Rename source files from .c to .cc.
	* %.c: Rename to %.cc.
	* configure.ac: Rename server.c to server.cc.
	* configure: Re-generate.
