- added a close_process method to process_io
- made use of it to get rid of dbg_detach

- added -minidump and -minidump <file> options to command line

Those options are to be used in remplacement of --auto to create a minidump
In the form --minidump <file>, the minidump will be created in <file>,
otherwise the filename will be automatically generated.

- rewrote auto mode as a specific set of commands to be run in
  regular parser, instead of hard coding those commands
- added a new function to store a set of commands to be executed
  in a file
- added 'echo' command to the parser functions
- got rid of dbg_action_mode
- added support of '--' on command line

fix the errors.

Remove unneeded structures and functions from d3d8_private.h, clean
some datatypes up and remove d3dcore_gl.h.

All functions that manipulate strings should have an Ansi and a
Unicode variant.
Forward the unqualified dll entry points to the Ansi variant for
backward compatibility.
We're not allowed to use unqualified entry points in Wine, so change
RegInstall() calls to RegInstallA().
Update win32.api.

- rewrite auto mode startup
- move part of auto handling to tgt_active.c

- moves gdb command line handling to gdbproxy.c
- using manifest constants to make code more readable

- move process attachment and process creation (related to command
  line handling) from winedbg.c to tgt_active.c
- tidy up argument parsing

- made be_process_io references 'const'
- make use of it for dbg_read_memory and dbg_write_memory

Move all code related to an 'active' target (ie a running process)
from winedbg.c to tgt_active.c.
