It has no effect on correctness, but interferes with compating internal state
of different implementations.

On reflection, the previous commit may have been ill-advised. There
are many calls to open_read_close() and most shouldn't be able to
access special devices. (Though in practice only a few are enabled
in busybox-w32.)
Nonetheless, I've implemented a new mechanism which uses the macro
MINGW_SPECIAL() to mark calls to functions that are allowed to
access special devices.
An unrelated change is to avoid compiling fputs_stdout() in
coreutils/printf.c for the POSIX build.

Calls to tls_error_die() embed the line number of the error in the
binary. Since some lines had been added to tls.c for the WIN32
port a POSIX build of the busybox-w32 source differed from upstream.
Avoid this by pushing the special handling of /dev/urandom down into
open_read_close(). tls.c is now unchanged from upstream.
The only differences in the POSIX build reported by 'objdump -s'
are now the GNU build id, the copyright date and the date of the
configuration.

Back in 2007, commit 0c97c9d43707 ("'simple' error message functions by
Loic Grenie") introduced bb_simple_perror_msg() to allow for a lower
overhead call to bb_perror_msg() when only a string was being printed
with no parameters. This saves space for some CPU architectures because
it avoids the overhead of a call to a variadic function. However there
has never been a simple version of bb_error_msg(), and since 2007 many
new calls to bb_perror_msg() have been added that only take a single
parameter and so could have been using bb_simple_perror_message().
This changeset introduces 'simple' versions of bb_info_msg(),
bb_error_msg(), bb_error_msg_and_die(), bb_herror_msg() and
bb_herror_msg_and_die(), and replaces all calls that only take a
single parameter, or use something like ("%s", arg), with calls to the
corresponding 'simple' version.
Since it is likely that single parameter calls to the variadic functions
may be accidentally reintroduced in the future a new debugging config
option WARN_SIMPLE_MSG has been introduced. This uses some macro magic
which will cause any such calls to generate a warning, but this is
turned off by default to avoid use of the unpleasant macros in normal
circumstances.
This is a large changeset due to the number of calls that have been
replaced. The only files that contain changes other than simple
substitution of function calls are libbb.h, libbb/herror_msg.c,
libbb/verror_msg.c and libbb/xfuncs_printf.c. In miscutils/devfsd.c,
networking/udhcp/common.h and util-linux/mdev.c additonal macros have
been added for logging so that single parameter and multiple parameter
logging variants exist.
The amount of space saved varies considerably by architecture, and was
found to be as follows (for 'defconfig' using GCC 7.4):
Arm: -92 bytes
MIPS: -52 bytes
PPC: -1836 bytes
x86_64: -938 bytes
Note that for the MIPS architecture only an exception had to be made
disabling the 'simple' calls for 'udhcp' (in networking/udhcp/common.h)
because it made these files larger on MIPS.
