d142cf7cea Hopefully fix Coverity CID 1008328 (Out-of-bounds write) in /bin/sh.
Replace the magic constant 127 in the loop interation count with
"PROMPTLEN - 1".

gethostname() is not guaranteed to NUL terminate the destination
string if it is too short. Decrease the length passed to gethostname()
by one, and add a NUL at the end of the buffer to make sure the
following loop to find the end of the name properly terminates.

The default: case is the likely cause of Coverity CID 1008328.  If
i is 126 at the top of the loop interation where the default case
is triggered, i will be incremented to 127 by the default case,
then incremented to 128 at the top of the loop before being compared
to 127 (PROMPTLENT - 1) and terminating the loop. Then the NUL
termination code after the loop will write to ps[128].  Fix by
checking for overflow before incrementing the index and storing the
second character in the buffer.

These fixes are not guaranteed to satisfy Coverity. The code that
increments i in the 'h'/'H' and 'w'/'W' cases may be beyond its
capability to analyze, but the code appears to be safe.

15b855a54e Restore the translation of armv6hf->arm when generating MACHINE_CPUARCH.
It turns out we need to leave this in place for a while so that people
running self-hosting armv6hf systems can do the builds necessary to update
to armv6 (which is now hardfloat by default).

ba8920d51c 1) POSIX prohibits printing errors to stderr here and require
returning NULL:

"Upon successful completion, initstate() and setstate() shall return a
pointer to the previous state array; otherwise, a null pointer shall
be returned.

Although some implementations of random() have written messages to
standard error, such implementations do not conform to POSIX.1-2008."

2) Move error detections earlier to prevent state modifying.

0378533250 Silence top(1) compiler warnings
The contrib/top code is no longer maintained upstream (last pulled 16 years
ago). The K&R-style followed by the code spews -Wimplicit-int and -Wreturn-type
warnings, amongst others. This silences 131 warnings with as little modification
as possible by adding necessary return types, definitions, headers, and header
guards, and missing header includes.

The 5 warnings that remain are due to undeclared ncurses references. I didn't
include curses.h and term.h because there are several local functions and macros
that conflict with those definitions.

1bed8c5452 When descending a shadow chain of objects, it makes no sense to update
the current offset (spelled: "fs.pindex") until it is known whether a
backing object exists.  In fact, if not for the fact that the backing
object offset is zero when there is no backing object, this update would
produce a broken offset.
