MFC elfdump improvements

r269092: 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.

r269143 (andreast): Further improvements on elfdump, to follow up r269092:

- Add ARM specific section header types.
- Add SHT_GNU_HASH section header type.
- Improve reporting of undefined tags in d_tags.
- Add DT_GNU_HASH tag.

r269337: add EM_AARCH64 64-bit ARM machine architecture

r269338: use existing ELF constants where available

r270303: 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.

MFC r265613, r267649: Handle ELF files with 65280 or more sections

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.

Don't dump core when the ELF file has no section headers. The ELF
core files created by gcore are among those.

More -Wmissing-variable-declarations fixes.

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'.

Don't extract the n_type value from the elf header, since it is never used

o Use C99 designated initializer to properly handle ELFOSABI_STANDALONE.
o In elf_get_byte(), cast through uint8_t and not char to avoid sign
extension.

Teach elfdump(1) about the SUNW_dof section.

Use the newly brought %U macro.

Build usr.bin/ with WARNS=6 by default.

Also add some missing $FreeBSD$ to keep svn happy.

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.

Synchronize usage() and SYNOPSIS, and fix them (flags are not
optional here). Sort options. Print the file name on error.

mdoc(7) police: Revision.

Spellcheck.

Add a man page.

Make WARNS=5 clean even on 64-bit platforms.

Make WARNS=5 on i386, (WARNS=1 on 64-bit platforms).

Try to tighten up the types a little bit to help debugging with GDB.

If we're going to build and install this on ia64, we might as well
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...

Like sh_types, dt_tags just aren't in consecutive order, so we have to move
away from indexing into an array. Also add Sun and GNU specific tags.

The defined sh_types's just aren't in consecutive order, so we have to move
away from indexing into an array.

Add a BSDL'ed util that displays information about ELF files.
This is simular to readelf(1) and objdump(1).
