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.

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.
r109332 introduced these three as DT_SUNW_*. Update to the correct
names already used elsewhere in FreeBSD and the Sun "Linker and
Libraries Guide"

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.

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.

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.

This provides a minor cleanup in elfdump; there are otherwise no
consumers in the tree. Old SUN documentation can be found for either
variant, but GNU binutils switched to DT_FEATURE around 2000.

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.

If e_shnum or e_shstrndx are at least SHN_LORESERVE (0xff00) then an
escape value is used to indicate that the actual value is found in one
of section 0's fields.

In addition to adding `static' where possible:
- bin/date: Move `retval' into extern.h to make it visible to date.c.
- bin/ed: Move globally used variables into ed.h.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.
- usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.
this involves the sign-extension of the high and low "word". Both
of which are 32-bit. The bug is especially harmful on ia64, where
0x9fffffffe0000000 is a common address (base of register stack).
This was invariably displayed as 0xffffffffe0000000.
The sign-extension is fixed by using {b|l}e{16|32|64}dec() where
applicable. Since elfdump(1) is not a bootstrap tool, dependency
on these functions is not a problem.
teach it about ia64 specific section types, dynamic tags and machine
type. This is a mostly insignificant change given the amount of
work that this tool obviously needs...
