[VAR] Replace cmdenviron with localvars
This patch replaces the cmdenviron mechanism for temporary command
variables with the localvars mechanism used by functions.
This reduces code size, and more importantly, makes the variable
assignment take effect immediately as required by POSIX.

[VAR] Fix poplocalvar leak
When a variable is marked as local, we set VSTRFIXED on its vp
recored. However, poplocalvar never clears this flag for variables
that were unset to begin with. Thus if you ever made an unset
variable local, it would get the VSTRFIXED bit and stick around

Instead of detecting EOF using the input layer, I'm going to
use the parser instead. In either case, we always have to read
ahead in order to complete the parsing of the previous node.
Therefore we always know whether there is more to come, except
in the case where we see a newline/semicolon or similar.
For the purposes of sh -c, this should be sufficient.

[EXPAND] Fix corruption of redirections with byte 0x81
In other ash variants, a partial implementation of ksh-like cmd >file*
adds and removes CTLESC bytes ('\x81') in redirection filenames,
preserving 8-bit transparency. Long ago, dash removed the code to add
the CTLESC bytes, but not the code to remove them, causing corruption of
filenames containing CTLESC. This commit removes the code to remove the
CTLESC bytes.
The CTLESC byte occurs frequently in UTF-8 encoded non-Latin text.

The first two occur because the alphabetic length specifier isn't being

treated as alphabetic so we fall off the end of the FDL_sizeof array with
undetermined consequences. Coreutils defaults to printing a double in

printf: fix format string sanity check
One of the tests for printf checks for an invalid bare '%' in the
format string:
$ busybox printf '%' a b c
printf: %: invalid format
On x86_64 a slightly different test doesn't work correctly:
$ busybox printf '%' d e f
printf: invalid number 'd'
printf: invalid number 'e'
printf: invalid number 'f'
On other platforms the test fails randomly depending on how the
arguments are laid out in memory.
There are two places in the code where strchr is used to determine if
a character in the format string is valid. However, strchr also returns
a valid pointer if the character being searched for is the null terminator
thus causing the code to incorrectly suppose that a valid character has
been found.
Add explicit checks for the null terminator.
