this patch sets the timer resolution in such a way that it is 10ms for
timeouts <= 200s and 5 / 100000 of timeout for longer timeouts.
There is no magic behind this fraction: it just gives 10ms at 200s and
it covers with some margin the drift we observe on the CAF for 1h delays
(117 ms vs 36 * 5 = 180ms).

With this change things on the CAF work fine.

1.  DispatchSignals(sig)
    Replace call to Abort(-1) with a call to Exit(sig) to
    allow CMSSW to flush buffers, close files and clean up
    after a fatal error.

2.  StackTrace()
    Enlarge string field widths to accommodate long function
    signatures for demangling.

    Enable use of GNU script, gstack, if available. Replace
    incorrect sed script in gstack. Modified gstack is available
    as $ROOTSYS/etc/gdb-backtrace.sh.

    Increase sizes of buffers for calls to and responses from
    the addr2line and cppfilt functions.

    The addr2line function doesn't know about paths so every
    library or executable name passed to it must include a full
    path. This is automatic for shared libraries. On the other
    hand, for main programs specified without a path, send
    `which main` and let the shell expand the name for us.

    For shared libraries, addr2line wants an offset into the
    file.  For main programs, it wants the absolute virtual
    address. Distinguish between these two cases and send
    the correct address.

   CpuInfo_t  *TSystem::GetCpuInfo() const
   MemInfo_t  *TSystem::GetMemInfo() const
   ProcInfo_t *TSystem::GetProcInfo() const

The SysInfo_t contains static system information:

struct SysInfo_t {
   TString   fOS;          // OS
   TString   fModel;       // computer model
   TString   fCpuType;     // type of cpu
   Int_t     fCpus;        // number of cpus
   Int_t     fCpuSpeed;    // cpu speed in MHz
   Int_t     fBusSpeed;    // bus speed in MHz
   Int_t     fL2Cache;     // level 2 cache size in KB
   Int_t     fPhysRam;     // physical RAM in MB
};

The CpuInfo_t contains global machine CPU load information:

struct CpuInfo_t {
   Float_t   fLoad1m;      // cpu load average over 1 m
   Float_t   fLoad5m;      // cpu load average over 5 m
   Float_t   fLoad15m;     // cpu load average over 15 m
   Float_t   fUser;        // cpu user load in percentage
   Float_t   fSys;         // cpu sys load in percentage
   Float_t   fTotal;       // cpu user+sys load in percentage
   Float_t   fIdle;        // cpu idle percentage
};

The MemInfo_t contains global machine memory and swap information:

struct MemInfo_t {
   Int_t     fMemTotal;    // total RAM in MB
   Int_t     fMemUsed;     // used RAM in MB
   Int_t     fMemFree;     // free RAM in MB
   Int_t     fSwapTotal;   // total swap in MB
   Int_t     fSwapUsed;    // used swap in MB
   Int_t     fSwapFree;    // free swap in MB
};

The ProcInfo_t contains current process information:

struct ProcInfo_t {
   Float_t   fCpuUser;     // user time used by this process in seconds
   Float_t   fCpuSys;      // system time used by this process in seconds
   Long_t    fMemResident; // resident memory used by this process in KB
   Long_t    fMemVirtual;  // virtual memory used by this process in KB
};

This first check-in provides only an implementation for Mac OS X. The Linux
and Win32 versions are coming tomorrow.

This is an optimization in TXNetSystem to avoid recording (and looping over)
too many helpers in TSystem::fHelper.

After this change, only the helper to the redirector is recorded, and the right
connection is searched inside.

Also added:
- an implementation of Unlink, which is useful to delete files on the cluster
  (activation of helper search in TUnixSystem::Unlink and TWinNTSystem::Unlink)
  Does not work (yet) with dirs, but this is a server side problem; Andy aware.
- a bit in EFileModeMask to flag 'offline' files, i.e. files existing but
  (temporarly) not available ... xrootd has the concept, for files to be
  staged, for example; the bit 0110000 was unused and it did fit, conceptually.

- don't use TUrl to strip off "file:" protocol string from file names
  as this was also striping off everything after # and ? tokens, making
  it impossible to e.g. stat local file names like .#bla#.

Implementing ConcatFileName and Which to not return a new char[]
to be deleted by the user, but operate on an existing TString.
because of backward compatibility issues I had to introduce new function
names.

   Which(...const char*,...) -> FindFile(...TString&,...)
   ConcatFileName(...const char*,...) -> PrependPath(...TString&,...)

The existing Which and ConcatFilename are now wrappers for the new
TString versions. The wrapping is done in TSystem, so all derived
classes need to implement FindFile and PrependPath now.
I've also fixed a few obvious problems and incompatibilities between the
windows and the unix versions; the VMS version is IMHO still broken. One
of the problems fixed: ConcatFileName(0,"name") returned "name" on unix,
but "\\name" on windows. It now returns "name" for all.
