From Gerri:
move non-persistent member fUrl that was in all derived classes to
TFile. It is accessable via the new method GetEndpointUrl() and will
return in the case of xrootd files the url of the node really having
the file (and not the generic redirector host id).
Also added code to better handle the case of many concurrent async
opens (keep a list of async open handlers).

introduce a more complete TSystem::GetPathInfo() method that takes a
new FileStat_t structure as argument. This FileStat_t structure mimics the
common struct stat. This allows for full support of the file mode bits
(via the new enum EFileModeMask and the inline function R_ISDIR(), R_ISCHR(),
R_SIBLK(), R_ISREG(), R_ISLNK(), R_ISFIFO() and R_ISSOCK()).
The TSystem derived helper clsses for the remote file access protocols
have been updated too (all already supported struct stat in their POSIX
layers). Modified rootd to also support FileStat_t. With this change we
can get rid of machine dependent file permission checking code in several
places, notably in the TGFSContainer, which now can correctly display
file attributes for remote protocols.

Mega patch to add support for large files (bigger than 2 GBytes)
----------------------------------------------------------------
==========>NEW VERSION 4.00/00 <===========
Because this new version has a considerable number of changes,
and new important additions by Philippe are scheduled for the coming days
we are starting a new major version 4.
-Support for large files
-Automatic schema evolution for foreign classes
-New data type Double32_t
Large files are currently tested only under Linux with gcc3.2.
Support for other systems will be gradually added in the coming days.
By default under Linux, files are created with the option LARGEFILE.
Note that when creating a Tree, the default maximum size for a Tree
is set to 1.9 GBytes. You can change this default value by calling
TTree::SetMaxTreeSize(Long64_t maxsize)
The implementation of this new feature has required changes in many places.
The files produced by this new version can still be read by old ROOT versions
if their size if smaller than 2 GBytes. And obviously, the new version
can digest old ROOT files.
WARNING: note the following backward incompatibility:
-TSystem::GetPathInfo has a new signature: (also TUnixSystem, TWinNTSystem, etc)
old: GetPathInfo(const char *path, Long_t *id, Long_t *size, Long_t *flags, Long_t *modtime);
new: GetPathInfo(const char *path, Long_t *id, Long64_t *size, Long_t *flags, Long_t *modtime);
-TFile::SysSeek and TFile::SysStat have a new signature (also TNetFile, TWebFile, etc)
old: Int_t SysSeek(Int_t fd, Long_t offset, Int_t whence);
Int_t SysStat(Int_t fd, Long_t *id, Long_t *size, Long_t *flags, Long_t *modtime);
new: Long64_t SysSeek(Int_t fd, Long64_t offset, Int_t whence);
Int_t SysStat(Int_t fd, Long_t *id, Long64_t *size, Long_t *flags, Long_t *modtime);
-TTree::SetMaxTreeSize has a new signature:
old: void TTree::SetMaxTreeSize(Int_t maxsize)
new: void TTree::SetMaxTreeSize(Long64_t maxsize)
All references to Seek_t have been replaced by Long64_t.

add capability to read directory structures via RFIO. This works via
the TRFIOSystem helper class (which derives from TSystem) that is loaded
by the plugin manager whenever one tries to access a rfio directory or file.
This helper class is used in the actual system class (TUnixSystem,
TWinNTSystem).

added the methods GetErrno() and ResetErrno(). They are needed so we can
override them in TRFIOFile. This so we can access the special rfio_errno.
The originally static methods in TRFIOFile have now been made normal methods.
