Synching my tree with cvs.

Synching my tree with cvs.

I'm committing all the little, but uncontroversial, changes that have
built up in my tree. This will result in an almost total recompilation for
you all but will mean that things are less painfull when the other changes
go in!

* Rename files syscall.[Ch] as systemcall.[Ch].

* Rename class Systemcalls as class Systemcall as one instance of the class
  represents a single child process. Remove the default constructor too.

* Add a running() method to class Timeout. Results in recompilation of almost
  the entire tree because pretty well everything depends on LyXView.h which
  #includes "frontends/Timeout.h", so...

* Make the Timeout instances in classes LyXView and minibuffer pointers,
  allowing us to forward declare class Timeout.

* Add LFUN_FORKS_SHOW and LFUN_FORKS_KILL to commandtags.h in anticipation
  of something wonderful!

* Add a signal showForks to Dialogs.h, again anticipating some real code.

* wrap the structs firster, seconder in frontends/controllers/helper_funcs.h
  in a namespace to prevent a clash with similarly named structs in
  support/lyxalgo.h

As you see, lots of irritating bits and pieces which don't make much sense in
themselves but do in light of the other changes I've got here.

I'll post the big changes to the list for proper perusal.
