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...
