Feature: Hard-coding the interface names to tap* is not always a good

The uid parameter is no longer needed since ip tuntap is used
internally. Remove it. Backward compatibility to 3 or 4 parameters is
still supported.

The parameter staging_bindir_native is no longer used. Remove it.
For now the script is backward compatible. With 4 parameters it logs an
error message but still works.

Commit d43c41fcaf061eaf8bff7bc03de19cdc80226796 refactors the script but
there's a missing '"' in one line, leading to the following message:
poky/scripts/runqemu-gen-tapdevs: command substitution: line 62: unexpected EOF while looking for matching `"'

ip tuntap provides the functionality that we obtained from tunctl. We only
needed tunctl when ifconfig was more available than ip. That isn't the case
now so we can drop tunctl and all the hoops we need to jump through to build
and provide it.

The *ip* command supports the creation and destruction of TAP devices since
2009 and might be more likely installed on systems then *tunctl*. Therefore
it should be tried to setup or teardown the TAP interface with *ip* before
falling back to *tunctl*.

The changes are mostly about early exit which causes indentation changes;
check with `git diff -w`. Another change is the check for ip by simply
calling it and deciding upon the exit code, if it's fine or not.

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.

Then we can get user's UID and GID rather than hardcode to 1000, e.g.:

The tunctl binary is here:
OE @ /OE/openembedded-core # find /OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/
/OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/

/OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/usr/bin/tunctl
But the script still complains that it cannot find tunctl:
OE @ /OE/openembedded-core # ./scripts/runqemu-gen-tapdevs 1026 1026 4 /OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/

Creating tap0
Error running tunctl: Error: Unable to find tunctl binary in '/OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/', please bitbake qemu-helper-native
The message is actually from runqemu-ifup, which is called from runqemu-gen-tapdevs as:
++ ./scripts/runqemu-ifup 1026 1026 /OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/
But runqemu-ifup expects 3rd parameter to be STAGING_BINDIR_NATIVE directly not just SYSROOT dir
STAGING_BINDIR_NATIVE=$3
because tunctl is then used as:
TUNCTL=$STAGING_BINDIR_NATIVE/tunctl
It looks like it got broken by:
commit cc5513bf7a6114e14bb307acb88a44e9cf0aed8a

Seemingly obvious fix would be to call runqemu-gen-tapdevs with path to STAGING_BINDIR_NATIVE in 4th parameter as well, but that won't work, because runqemu-gen-tapdevs checks for TUNCTL=$SYSROOT/usr/bin/tunctl
OE @ /OE/openembedded-core # ./scripts/runqemu-gen-tapdevs 1026 1026 4 /OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/usr/bin/
Error: /OE/build/oe-core/tmp-glibc/sysroots-components/x86_64/qemu-helper-native/usr/bin//usr/bin/tunctl is not an executable
I've tested that with this change it can call tunctl:
