Sync with wrstuden-revivesa-base-2.

Remove the \n and tabs from the __COPYRIGHT() strings.
Tweak to use a consistent format.

detect more errors from printf/malloc.

Remember to consume input bytes when processing '\0nnn' for %b formats

Remember to consume input bytes when processing '\0nnn' for %b formats

- KNF, WARNS=3, pass lint.
- Simplify octal parsing code.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

Revert previous.  'None' means that the "Utility Syntax Guidlines" apply.

Remove getopt() loop, IEEE 1003.1 doesn't say that printf(1) should conform
to the "Utility Syntax Guidlines".
Fixes PR 21970.

Fix the output of NUL bytes within %b formats.
(Approved by Christos)

Fixes from David Laight:
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
  (so I could unset -e PS1 before running the test shell...)

Complete declaration of progprintf() to fix build problem in csh(1).

Remove #ifdef __STDC__. De-__P() and ANSIfy. Fix a prototype mismatch
uncovered by this.

Change to use {u,}intmax_t internally (was: (unsigned) long).

brace pollution, and char -> unsigned char

include unistd

add <unistd.h> to fix compiler warning

s/index/strchr

"merge" lite-2.  our printf is already kinda different...minor changes only.

Fix compiler warnings.

lint and KNF changes.  (mostly casting returns to void to quiet lint.)

RCS ID police

4.4BSD-Lite2

Simplify conversion of "quoted" numeric arguments.

Code to check if conversion (by strtol(), strtoul(), or strtod()) was
identical, so I moved it into its own function.

Add and use getulong() to handle %u, %o, %x & %X formatting directives.
It was using getlong(), which caused values larger than LONG_MAX to be
truncated to LONG_MAX.
As recommended by 1003.2, print warning messages when argument cannot be
converted to value or is out of range.

Handle format strings error correctly.

Error in hextobin() macro messed up hex escape constants.

Oops! get rid of the free(), mklong()'s buffer no longer malloc()'d.

Return from main() if a \c escape is encountered in a %b string (was an exit()).
Use macro constants for "skip1" and "skip2" instead of assigning them
each loop iteration.
Reformat the multi-case entries in the "big switch" so the lines don't wrap.

Move all the code from do_printf() into do-while loop in main().  I need
to be able to return from main() when a "\c" in a %b string is encountered.

Merged in most of the changes from 4.4 necessary to make printf a sh
and csh builtin --- still need to handle the one remaining exit() in
the SysV escape string handling code.

Changes required to make printf utility POSIX.2 compliant:
 * Escape characters in the string needed to be processed as they were
   encountered, otherwise a "\000" octal constant would prematurely
   terminate the formatting string.
 * Implemented the %b, SysV echo(1) compatibility, formatting directive.

Add RCS identifiers.

Cleanup for GCC 2.
