9e69bea9f1 Add a "fillchar" command line argument to dd(1) that permits the user 
to specify an alternative padding character when using a conversion
mode, or when using noerror with sync and an input error occurs.  This
facilities reading old and error-prone media by allowing the user to
more effectively mark error blocks in the output stream.

43cc55dd2f 1) Rev.1.35 of dd.c has a more serious regression. It backs out rev.1.31, 
thus breaking systems with unpolluted <sys/stat.h>'s.

2) Back out an initialisation of a variable in BSS.

3dc2f99bef Previous commit broke dd(1)'s I/O summary when it's terminated by a 
signal.  Fix it by adding an explicit call to summary() in terminate()
(it was previously called implicitly by exit() because summary() was
registered with atexit()).  summary() is supposed to be signal-safe--
it handles SIGINFO almost exclusively--so this should be safe.

708c7f49eb Add iseek= and oseek= aliases for the preexisting skip= and seek= 
operands.  Can _YOU_ tell skip= and seek= apart with 100% accuracy
every time?

This also seems to make us option-for-option compatible with the
Solaris dd(1).

277eda1860 Do proper constification in args.c. This shuts up -Wcast-qual (thanks, 
bfumerola for that pointer!) in GCC complaining about losing a const.

While I'm here, might as well mark in the Makefile that I'm the
${MAINTAINER}.  It seems like that's what everyone's doing these days.
