New implementation of all printf functions. It's stream based (like MS one is) rather than buffer based (like our old is). Floating point is not 100% finished, but current implementation is good enough to boot. It can be enabled by a config switch.

The cache manager rewrite I started years ago has finally appeared in
ReactOS' trunk and although at this point it's not quite perfectly
integrated, it's enough to boot up the bootcd or livecd. To check out
the more mature original, check out arty-newcc-reactos, branch
arty-newcc on bitbucket.org . Amine Khaldi encouraged me quite a bit
to not give up on it, and was able to reach out and be an advocate
when i really wasn't able to. Others agree that the time has come to
begin removing the old cache manager. I expect the remaining problems
in the version going to trunk will be taken care of relatively
quickly.
The motivation for this effort lies in the particularly hairy
relationship between ReactOS' cache manager and data sections. This
code completely removes page sharing between cache manager and section
and reimagines cache manager as being a facility layered on the memory
manager, not really caring about individual pages, but simply managing
data section objects where caching might occur.
It took me about 2 years to do the first pass of this rewrite and most
of this year to fix some lingering issues, properly implement demand
paging in ReactOS (code which didn't come with this patch in a
recognizable form), and finish getting the PrivateCacheMap and
SharedCacheMap relationship correct.
Currently, the new ntoskrnl/cache directory contains an own
implementation of data file sections. After things have settled down,
we can begin to deprecate and remove the parts of ReactOS' section
implementation that depend on a close relationship with cache
manager. Eventually, I think that the extra code added to
ntoskrnl/cache/section will be removed and ReactOS' own sections will
replace the use of the special MM_CACHE_SECTION_SEGMENT in the cache
path.
Note also, that this makes all cache manager (and new section parts)
use wide file offsets. If my section code were to take over other
parts of the ReactOS memory manager, they would also benefit from
these improvements.
I invite anyone who wants to to peek at this code and fix whatever
bugs can be found.

Reenable testing on undefined properties, they are treated as being empty now. This feature got lost when moving the <if> block parsing entirely to rbuild in r34852.
Should fix the Release build properly _with_ touching rbuild :-)
svn path=/trunk/; revision=37811
Change the <if> logic in ReactOS-general.rbuild (and ReactOS-arm.rbuild for the ARM guys) accordingly. This also supersedes DBG_OR_KDBG, which never worked properly for Release builds anyway.
Should fix the Release build without touching rbuild itself :-)

Add assertions to this function, to make sure PFN access is always valid (previous code would sometimes KEBUGCHECK(0) without a real explenation if such cases were encounted -- but developers randomly chose which functions would be protected).
Also, since PFNs are 0-based, do allow Pfn == MmPageArraySize if someone is reading the last PFN on the system.
Finally, protect some of the functions which were accessing the PFN entries outside the PFN list lock.

- Remove assumption that GDB=1 automatically means -O0. This is wrong, optimization and debugger should be controlled independently.
- Cleanup blah-blah from config.template.rbuild.
svn path=/trunk/; revision=31435
- Update targets to pentium to take advantage of cmpxhg8b when possible. (ROS won't run on 386/486 anyway).
- Fix some compiler problems when building with -O3.
svn path=/trunk/; revision=26274
- Support _WINKD_ in ntoskrnl.rbuild to build KD64 instead of KDBG/KD if it's enabled.
- Remove some incorrect kernel exports.

- Yeah, this adds another regression on top of the new Ob stuff, but in the end it's for the better, as it removes more race conditions and buggy code.
- This whole week I've fixed about 45 bugs and removed a dozen race conditions, sorry for the 2-3 regressions, they will be fixed ASAP.
- DELETE MAKEFILE.AUTO BEFORE BUILDING THIS BUILD.
