begun conversion to new synchronization

vmm_pageFault2() implemented

cleaned up dependencies. rewrote vmmCopyVirtualSpace. does not compile ...

CVSn: ----------------------------------------------------------------------

updated mememory management

reverting to old vmm. i may have modified something accidently when i wasted time indenting the code.

new scheduler!

code clean up

task switching - We now are using software switching to be consistant with the rest of the world because all of this open source freaks gave me a hard time about something I liked. There doesn't seem to be any gain in performance but it is working fine and flawlessly

TCA Is A BONER!!!!

Changes

Major: ...

Pages now have strict security enforcement.
  Many null dereferences have been resolved.
  When apps loaded permissions set for pages rw and ro

bah

Major: ...

Disconnected page 0x0 from the system... Unfortunately this broke many things
  all of which have been fixed. This was good because nothing deferences NULL
  any more.

Things affected:
  malloc,kmalloc,getfreepage,getfreevirtualpage,pagefault,fork,exec,ld,ld.so,exec,file

Put in a test for 0x0

test code, fixes and the like

Changes... mark let me know if you fault at pid 185 when you type stress

Lots of changes to the vmm subsystem.... Page faults have been adjust to now be blocking on a per thread basis not system wide. This has resulted in no more deadlocks.. also the addition of per thread locking has removed segfaults as a result of COW in which two tasks fault the same COW page and try to modify it.

vmm_pageFault: deadlock resolved thanks to a propper solution suggested by geist

vmmPageFault: had a potential memory leak here for one page it was still using sysID on certain COW scenarios
