Ensure self.data isn't accessed without assignment. Also clean up old style
popen use and replace with modern/simpler subprocess.

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.

BPF Linux ELF objects are generated with kernel-selftests with
>= 4.18 kernel and when clang is enabled which packages BPF objects
into packages, therefore recongnise this as a valid ELF target
Add a selftest for BPF
Do not flag BPF objects in target, since they pretty much will be ok for
most of kernels architectures we care do support BPF

getVar() now defaults to expanding by default, thus remove the True
option from getVar() calls with a regex search and replace.
Search made with the following regex: getVar ?\(( ?[^,()]*), True\)

The ELF parser was assuming that the segment tables are in the first 4kb of the
binary. Whilst this generally appears to be the case, there have been instances
where the segment table is elsewhere (offset 2MB, in this sample I have). Solve
this problem by mmap()ing the file instead.
Also clean up the code a little whilst chasing the problem.

Add a function (and test suite) to turn the ELF machine field (e_machine) into a
string, so we can tell the user "x86-64" instead of 0x3E.

file() API doesn't exist in python 3, convert to open(). Also handle
some cases where files aren't closed. Compatible with python 2.7.

It's useful to know if a binary is statically or dynamically linked, so add a

Instead of raising a generic Exception that can't be handled specifically, raise
a ValueError. Also update the callers so any unexpected exceptions are not
ignored.
Also, rename isBigEngian() to isBigEndian().

When opening an ELF file check that a filename points to a normal file before
attempting to open it, as if the file turns out to be something more exotic like
a FIFO it could hang forever.

Currently objdump command is invoked from the STAGING_BINDIR_TOOLCHAIN
directory. In case of external toolchain if this directory doesn't
exist then objdump fails to execute. Instead of hardcoding the path
it should search PATH to find it.

This avoids propagating a failure if we encounter an ELF file
that objdump can't parse for any reason. Some versions and/or
configurations of objdump will refuse to read files for "the
wrong" architecture.

Various different QA checks are based on essentially the same data from
the ELF program headers. Calling objdump to extract it repeatedly is
inefficient, particularly if the shell is involved. Instead, let's
cache the output from objdump inside the qa.elf object and allow it to
be reused by multiple tests.
Also, using objdump instead of scanelf to check for bad RPATHs (in the
same way that the useless-rpaths check was doing already) allows the
dependency on pax-utils-native to be dropped.

Fix the way the ELF size is compared to ensure that incorrectly
sized ELF binaries are captured during the file scan.
lib/oe/qa.py is changed to accept a bitsize as a parameter. Instead
of previously defining true/false, it now takes "0" undefined, "32"
32-bit, and "64" 64-bit as the size argument. This allows us to
preserve existing behavior of only loading one ELF type, while
allowing the function to be able to discover the size on it's own.
