ffae400179 meta/lib+scripts: Convert to SPDX license headers
This adds SPDX license headers in place of the wide assortment of things
currently in our script headers. We default to GPL-2.0-only except for the
oeqa code where it was clearly submitted and marked as MIT on the most part
or some scripts which had the "or later" GPL versioning.

The patch also drops other obsolete bits of file headers where they were
encoountered such as editor modelines, obsolete maintainer information or
the phrase "All rights reserved" which is now obsolete and not required in
copyright headers (in this case its actually confusing for licensing as all
rights were not reserved).

More work is needed for OE-Core but this takes care of the bulk of the scripts
and meta/lib directories.

The top level LICENSE files are tweaked to match the new structure and the
SPDX naming.

10a14af4ca oe.path: Add copyhardlink() helper function
This function creates hard links if possible, falling back to copying
the file if the destination is on a different volume to the source.

The docstring for copyhardlinktree() is also updated to make the
difference between the two functions a little clearer.

This is a function much like shutil.which or bb.utils.which, retaining
shutil.which-like function semantics, bb.utils.which's support for
returning available candidates for signatures, and most importantly,
supports wildcards, returning only the first occurrance of each found
pathname in the search path.

9b49883f2f lib/oe/path: implement is_path_parent()
In a few places we have checks to see path B is the parent of path A, by
adding / to the end of the path B and then seeing if path A starts with
the suffixed path B. Unfortunately there are two potential flaws:
(1) path A needs to be suffixed with / as well or the directory itself
won't match (semantics perhaps, but in a lot of scenarios returning True
is correct); (2) you need to run os.path.abspath() on both paths first
or you will wrongly return False for some relative paths where you
should return True. Let's solve this once and for all by writing a
function that takes care of these and put it in oe.path.

e36fbb3382 oe/path.py: copyhardlinktree: don't overwrite existing symlinks
Before GNU tar 1.24, only the archive creation command had the '-h'
argument to preserve and follow symlinks. After >= 1.24 via commit
14efeb9f956e38d7be (tar: --dereference consistency) the capability to
preserve symlinks was also added to the archive extraction command.

-h is default at archive creation but is not default at extraction,
meaning that it will replace symlinks with directories even if the
original filesystem directory tree and archive contains them.

Add -h to the copyhardlinktree extraction step so the build can
support symlinks in variables like ${DEPLOY_DIR_IPK/RPM/DEB}.

08dfb89301 oe/path.py: fix for "Argument list too long"
Issue: LIN9-1648

Fixed when len(TMPDIR) = 410:
$ bitbake core-image-sato-sdk
[snip]
Subprocess output:
/bin/sh: /bin/cp: Argument list too long

ERROR: core-image-sato-sdk-1.0-r0 do_rootfs: Function failed: do_rootfs
[snip]

This is because "copyhardlinktree(src, dst)" does "cp -afl src/* dst",
while src/* is expanded to "src/file1 src/file2, src/file3..." which
causes the "Argument list too long", use ./* as src and change cwd in
subprocess.check_output() to fix the problem.

822c708e8f oe.path: fix copyhardlinktree()
The change to preserve extended attributes in copytree() and
copyhardlinktree() (e591d69103a40ec4f76d1132a6039d9cb1555103)
resulted in an incorrect cp invocation in copyhardlinktree() when
the source directory contained hidden files.

This was because the passed src was modified in place but some code
paths expected it to remain unmodified from the passed value.
Resolve the issue by constructing a new source string, rather than
modifying the passed in string.

We have to drop the use cpio in "Copy-pass" mode in copyhardlinktree()

revert back to using cp with different patterns depending on whether
or not the directory contains dot files.

1131507d46 lib/oe/path: Fix tar invocation with --no-recursion
tar's --no-recursion flag only applies to files mentioned after the
flag, which made it a no-op in this invocation of tar, because it was at
the end of the command line.

This is simple to verify with GNU tar 1.29:

| $ mkdir foo
| $ mkdir foo/dir
| $ touch foo/dir/file
| $ tar -cf - foo --no-recursion | tar t
| foo/
| foo/dir/
| foo/dir/file
| $ tar -cf - --no-recursion foo | tar t
| foo/

Modify the code so that it actually does what the comment says by moving
the flag in front of the --files-from argument.

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).

61823f6194 path.py: Deal with race issue
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.
