cf8fb39f7d elfdump: correct DT_AUXILIARY / DT_USED / DT_FILTER definitions
r109332 introduced these three as DT_SUNW_*. Update to the correct
names already used elsewhere in FreeBSD and the Sun "Linker and
Libraries Guide"

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.

4d52a0fd97 Rename DT_FEATURE_1 to DT_FEATURE
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.

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.

ac2ded1df3 Fix sign-extension bug for 32 and 64-bit values. For 64-bit values
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.
