Centralized output handling (preparation for console usage).
Fixed a few debug information reading options (stabs and sym).
Started a framework to hold debugger's internal variables.
Added watch (hardware assisted debugging) and whatis (type of expr) commands.
Fixed some issues in local vars handling (stabs parsing & registers optimization).
Execution context (mode, steps...) are now linked to a thread.
Removed some X11 crst hacks.
Rewrote info/walk commands.
Removed direct debugger invocation code (and moved the rest to the new
winedbg.c file).
