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()
can end up with its fd. Leave it open and limit it to no rights
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.

3a4b59a2cf elfdump: handle STT_SPARC_REGISTER
STT_SPARC_REGISTER is a SPARC-specific symbol type specified by the
Sparcv9 ABI to provide some information on register use by the object.

Also rework st_info type lookup to avoid out-of-bounds array access.

ccfb965433 Add META_MODE support.

WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

b385405966 elfdump: Improve section type reporting
The SHT range 0x70000000-0x7fffffff is processor-specific.  Pass the
ELF machine type header to sh_types so the section header type name can
be reported correctly for the given processor.

For all ranges report the actual value for unknown types.

Add MIPS-specific type SHT_MIPS_OPTIONS.
