undo change of this morning. Warnings are due to issue in generated dictionary
code not in the headers per se.

Set property svn:eol-style LF on all source and Makefiles. This should avoid
problems with Win32 line endings ending up in the repository. All MS tools
support LF eols fine.

From Paul:
Modify TRefTable, TBranchRef, and TBranchElement so that the small
integer which is assigned to identify a TBranchElement by TRefTable
is cached so that we need to find it only once, instead of at every
call to TBranchElement::GetEntry() or TBranchElement::Fill().

 -The enum kHaveWarnedReadingOld is becoming public instead of protected.
 -The inclusion of TFile.h has been removed.
 -TRefArray::Streamer makes use of TVirtualIO::GetLastProcessID.

With these changes TRefArray is now independent of the I/O sub-system.

From Axel:
this patch issues a warning once per TRefTable, if a file is being read
that contains an old version of TRefTable and multiple TProcessIDs. In
this case one _can_ have a corrupted TRefTable, due to several processes
re-using the same UIDs.

From Axel:

Add support for auto-loading of TRefs from multiple TProcessIDs:
TRefTable now stores 2d arrays of branch numbers to load [PID][UID] (via
FillBuffer). The PID index <-> TProcessID-GUID mapping is stored via
TRefTable::Streamer (i.e. once per TTree). Lookup is cached. This change
is both backward and forward compatible, both concerning the interface
and .root files. Only exception is TRefTable::fParentIDs, which is now
only streamed via FillBuffer / ReadBuffer, not as a member of TRefTable.

Minor side-notes:
* Speed-up in TRef::GetObject de-referencing (only once call to
TProcessID::GetObjectWithID).
* No re-reading of a branch if it was already read for an event (if
TBranchRef's fReadEntry == branch-to-autoload's fReadEntry then don't
call GetEntry on it).
* Added getter for TProcessID::fgPIDs->Size()
* updated doc for TRef, TRefTable, TBranchRef, to reflect the current
status of auto-loading.
---

The only change that's breaking backward compatibility (as mentioned
above) is the clear split between per-entry and global streaming of the
TRefTable: there is no use in storing the fParentIDs[][] array (and
fN[]) as part of the TTree members - it should only be stored as part of
the TTree entry. So I've marked them as //!; they're made persistent in
TRefTable::FillBuffer.

The member TRefTable::fSize is only around to suppress a warning in the
schema evolution algorithm (it was a counter before, and the schema
evolution algo is unhappy about fSize missing in the new class
definition, nor does it appreciate fSize being marked as //!). This is
ugly, but I prefer it over a custom streamer.

The patch should fix the following issues:
* autoloading doesn't work because TRefs were created by different
processes,
* changed objects magically overwritten in memory due to re-loading of
referenced objects

When cloning a TTree and removing some of the branches, if we have
a TBranchRef, we need to completely reset the TRefTable (which caches
the address of the branches that contains referenced objects).
Thanks to Reiner Hauser for discovering and solving his issue.

Improve the functionality of the TRefTable.
The new algorithm
  -does not require a pointer to the TRefTable in TFile.
  -can automatically load the branch of a Tree when calling TRef::GetObject
  -works when writing/reading multiple Trees in parallel

Add a new class
// TRefTable
//
// A TRefTable maintains the association between a referenced object
// and the parent object supporting this referenced object.
// The parent object is typically a branch of a TTree.
