Avoid doing seeks on the physical file reprensation when it is not absolutely necessary
(i.e. it is not need if we are going to pick the data from our cache).
Introduce a SetOffset to change fOffset (i.e. the logical position in the file) without doing a lseek.
Introduce ReadBuffer(char * buf, Long64_t pos, Int_t len) to avoid the lseek when the data is in the cache.
See <http://savannah.cern.ch/bugs/?69845>

Import from the vendor branch new version of 'xrootd' (20091102-0415-root).
This version contains some important fix in the client 'readv' needed by ALICE
and new cache policies on the client side. It also contains the new listing
features implemented recently in the 'cns' module.

From Fabrizio & Gerri:
Patch enabling asynchronous reading via XROOTD; a new method TFile::ReadBufferAsync
is introduced which gets appropriately overritten in TXNetFile .
The new feature can be enabled / disabled via the env 'TFile.AsyncReading' in .rootrc,
the default being ON.
The patch also cleans up the netx section in the system.rootrc, by removing
very old unused variables and commenting and setting appropriate default
values for the others (no additions, except for the comments).

From Gerri:
Andy has decided to rename and move some utilities classes inside XROOTD.
Some of them are used in ROOT too. In preparation for this I have tried to
remove as much as possible our dependence on that.
In TXNetFile there is an instance of XrdOucRecMutex which should become a
recursive TMutex. The patch attached does this.

From Andreas and me:
- take into account the static settings of opentimeout and
only staged files. If you don't have the change in xrootd,
the timeout does nothing - it just sets an environment
variable. Indeed, xrootd just returns, if the requested waittime of
the server is bigger than the timeout. For the moment,
there is no better way, but it helps to avoid blocking and
does what we need for analysis.
- removed TXNetFile::Size(), GetSize() should be used.

From Andreas:
TAlienFile inherits now directly from TXNetFile. This was possible by
introducing another factory function in TAlienFile (TAlienFile::Open),
moving some private to protected members and changing some function to
virtual in the parent classes. For the new factory function of the plubing
rootrc.in had to be modified.
Using the occasion, I have also implemented that, that
TAlienFile tries automatically to open any of the existing images of a
file, starting with the 'closest' one, if it fails with the next
replica aso. This is implemented right now only for reading. It is not
ought to do loadbalancing by random shuffling of the SE order.
There are some changes in TAlienCollection for Panos, to build the 'and'
of two TAlienCollections and to read evelist from the xml file.
Some memory leaks have been fixed in TAlienResult/TGridResult etc.
Finally to have a consistent file name (e.g. a TAlienFile has it's LFN as
a filename - eventhough it inherits from TXNetFile, which does not like
LFN's), I had to introduce another argument to TXNetFile (in the end with
a default value), to tell TXNetFile, that is has to open an xrootd url,
but it has to 'carry' another name. The normal functionality is not
touched by this.

From Gerri:
This patch implements 3 new static methods in TFile and the activation of
the asynchronous open mode in TXNetFile. There is a additional argument in
the main constructor of TXNetFile, hence the change in the plug-in entry in
rootrc.in.
The new methods in TFile are:
1. TFileOpenHandle *TFile::AsyncOpen(const char *fn, ...)
This method accepts the same arguments as the stardard TFile::Open(...),
submit the open request and returns an opaque object to be used to test
the status of the request and to finalize the opening.
2. TFile *TFile::Open(TFileOpenHandle *)
This new Open signature finalize the asynchronous open request
3. TFile::EAsyncOpenStatus TFile::GetAsyncOpenStatus(TFileOpenHandle *)
This method returns the status of the asynchronous open request without
blocking.

From Gerri:
The result of TFile::Init was not checked and this lead to an unexpected
behaviour in some cases.
Also, I've added the possibility (optional) to change the relevant envs on
the fly, which is useful in some cases.

From Gerri:
This is the patch to import the new XROOTD and to enable TXNetSystem.
Three files:
- 'adds-netx.tgz' contains the new class TXNetSystem;
- 'xrootd-20051026-1709.src.tgz' is the tagged version of XROOTD
- 'cvs-patch' the modifications needed to integrate the two things in ROOT:
- config/rootrc.in:
add plugin info for TXNetSystem
- base/src/TSystem.cxx:
fix the number of arguments in loading the TXNetSystem plugin
- netx/inc/TXNetFile.h, .cxx:
make a couple of generic auxilliary methods static so that they can be
used by TXNetSystem
- net/inc/TNetFile.h, .cxx:
add Create method in TNetSystem, used by TXNetSystem to re-use the
open connection in case of rootd
- net/inc/TFTP.h, .cxx:
additional 'TSocket *' argument in the constructor to allow re-using an
open connection; default behaviour not changed
- netx/inc/LinkDef.h:
add pragma statement for TXNetSystem
- netx/Module.mk:
add support for building on an external XROOTD distribution
- xrootd/Module.mk:
changes to use the new version; still using the 'classic' configure
script:
will move to autoconf with the next patch
