[58/58] gdbserver: finish turning the target ops vector into a class

Message ID 10770a54e442c92aa3869813131ac84ecc6890da.1581410936.git.tankut.baris.aktemur@intel.com

  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.

So to follow up to the comment in the previous patch,
I don't think this is better than the other way around, of keeping
the "the_linux_target" global, like GDB does.  The global approach has
the advantage that auxiliary functions in linux-low.c and siblings can
refer to the global without needing to pass around a "this" pointer,
for example.  This object is a singleton, so should be OK.

Thanks,
Pedro Alves
