Some versions of grep don't treat '\s' properly. When building perf on such
systems and using a kernel tarball the perf version is unable to be determined
from the main kernel Makefile and the user is left with a version of '..'.
Replacing the use of '\s' with '[[:space:]]', which should work in all grep
versions, gives a usable version number.

This gets rid of the default version fallback for Perf and
changes it so that it returns the version of the kernel from
it's Makefile (if sources were not from git, ie. if it was
downloaded from a tarball)

Changes the Perf --version string such that it shows the kernel
version as suggested by Ingo as follows:

That way the perf that comes with v2.6.34 will be:

  perf version v2.6.34

while interim versions will have the version of the interim
kernel - for example:

 perf version v2.6.35-rc4-70-g39ef13a4

This functionality was already in the perf version generator
file except that it was looking for a .git in the perf directory
instead of the kernel directory.

We released the first version of perf with 0.0.1 in v2.6.31,
time to double our version number to 0.0.2 ;-)

Several people have suggested that 'perf' has become a full-fledged
tool that should be moved out of Documentation/. Move it to the
(new) tools/ directory.

Clean up the top level directory a bit by moving all the helper libraries
to util/*.[ch].

First very raw version at having a central 'perf' command and
a list of subcommands:

  perf top
  perf stat
  perf record
  perf report
  ...

This is done by picking up Git's collection of utility functions,
and hacking them to build fine in this new environment.
