c35530f464 elfdump: Add -E to test if a file is an ELF binary.
This is intended to replace potentially unreliable checks like:

	file -b $1 | grep -q '^ELF ..-bit .SB executable'

f37e7f527b elfdump: chase ABI tag note name change from r232832
r232832 changed the ABI tag note name from .note.ABI-tag to .note.tag.
Follow suit in elfdump.

Elfdump's note parsing is very basic and should be significantly
reworked, but for now just restore the broken functionality.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

9e8f606352 elfdump: limit STDIN to no rights rather than closing it
Closing stdin/stdout/stderr is often a bad idea as a future open()

instead.

06403dbce5 elfdump: adjust stdout/stderr capabilities
stdio uses fstat and the TIOCGETA ioctl. Also collapse the
cap_rights_limit and new cap_ioctls_limit calls into one if statement.
Errors here are not actionable by the user and distinguishing stdout
from stderr doesn't really have value.

For all ranges report the actual value for unknown types.

Add MIPS-specific type SHT_MIPS_OPTIONS.
