As we now require Python 2.7 and os.path.relpath() was added in 2.6 we can now
drop the reimplementation in oe.path.
oe.path.relative is simple now a wrapper that changes the order of the arguments
and it's use discouraged.

copyhardlinktree()
Files named .* in the top level of directories handled by this function
were getting lost after the directory copying command was fixed. Rather
than complicate the function further, use cpio instead.

With the directory copy was added to avoid race issues, it wasn't noticed that
tar was recursing the directories and copying files too. This is completely
crazy when we hardlink those files in the next command.
Resolve the issue by telling tar not to recurse. This gives a significant
performance boost to various parts of the system (do_package for linux-yocto
256s -> 178s for example).

tar version 1.27 returns:
tar: --same-order option cannot be used with -c
with the commandlines we have been using. We can remove the -s option (which
is --same-order) to remove the error.

In python 3 print is a function call. In some cases bb.note is a more
appropriate call to make.

Update older code to use modern exception handling syntax which
is the form accepted by python 3.

The change to use copyhardlinktree in some of the sstate code instead of
copytree exposed a race condition. This is due to cp failing if it finds
a directory doesn't exist yet some other process creates it while cp was
trying to create it itself. tar doesn't error in this case.
To fix this we need to create the directory structure with tar, then
use cp to hardlink the files. Messy but probably worth doing.
I also took the opportunity to remove src_bak since the code is neater
without it.

Make hard links for staging files instead of copy to save the disk space
(3G will be saved for a core-image-sato build), and it doesn't affect
much on the build time.
The following directories are affected:
1) The sysroot
2) The DEPLOY_DIR
3) The pkgdata

Some use cases in OE operate on symlinks which dangling path components.
Assume that these are directories instead of raising ENOENT.

Various parts of the buildsystem have to work with symlinks. Resolving
them is not trivial because they are always relative to a sysroot
directory.
Patch adds a function which returns the destination of a symlink by
assuming a given path as the / toplevel directory. A testsuite was
added too.

optimisation
Add a function which copys a tree as a set of hardlinks to the original
files, then use this in sstate to reduce some of the overhead of sstate
package creation since the file isn't actually copied.

The bb and os modules are always imported so having these extra import calls
are a waste of space/execution time. They also set a bad example for people
copy and pasting code so clean them up.

This method allows you to convert an absolute symlink into a
relative one.

Using "1" with getVar is bad coding style and "True" is preferred.
This patch is a sed over the meta directory of the form:
sed \
-e 's:\(\.getVar([^,()]*, \)1 *):\1True):g' \
-e 's:\(\.getVarFlag([^,()]*, [^,()]*, \)1 *):\1True):g' \
-i `grep -ril getVar *`
