echo: make escape sequences depend on fancy mode
Currently when you disable fancy echo, escape sequences are hardcoded
enabled (e.g. as if you used `echo -e` all the time). The opposite
behavior is more desirable (always disable -e support) because:
* This seems to contradict the spirit of the kconfig help text (where
it says enable support for -n/-e flags), although you could say that
we aren't supporting the -e flag directly as `echo -e` will show the
-e flag.
* POSIX makes escape sequences optional, and even says they are there
only on XSI-conformant systems.
* It saves space (~100 bytes on x86_64).
* It makes things faster!
* It makes it behave more like bash where you need an explicit -e flag
in order for escape sequences to be interpreted.

- when lines are read from a file count the total number of lines

Commit
503a0b8 from git://git.kernel.org/pub/scm/utils/dash/dash.git
by Herbert Xu says:
>The parsebackquote flag is only used in a test where it always has the
>value zero. So we can remove it altogether.
The first statement is incorrect: parsebackquote is non-zero when
backquotes (as opposed to $(...)) are used for command substitution.
It is possible for the test to be executed with parsebackquote != 0 in
that case.
The test is question checks whether quotes have been closed, raising
the error "unterminated quoted string" if they haven't. There seems
to be no good reason to allow unclosed quotes within backquotes. Bash,
hush and dash (after commit
503a0b8) all treat the following as an error:
XX=`"pwd`
whereas BusyBox ash doesn't. It just ignores the unclosed quote and
executes pwd.
So, parsebackquote should be removed but not for the reason stated.

libbb: Enable support for !CONFIG_MULTIUSER
Linux recently gained a new config option, CONFIG_MULTIUSER, that makes
support for non-root users optional. This results in a number of syscalls
being disabled: setuid, setregid, setgid, setreuid, setresuid, getresuid,
setresgid, getresgid, setgroups, getgroups, setfsuid, setfsgid, capget,
capset.
Currently a number of busybox applets, including login, struggle to run
when CONFIG_MULTIUSER is disabled. Even the root user is unable to login:
login: can't set groups: Functi
This patch adds code to make change_identity() a nop on single user
systems. It works by recognising the signature errno value (ENOSYS, due
to the system calls being disabled) and, to avoid security risks, only
deploys when the current uid and target uid is the same.
After the patch is applied any attempt to switch to a non-root user will
fail. Thus a badly configured userspace (for example, one that tries to
start a daemon as a non-root user when the kernel cannot support this)
will report errors as one would expect.

i2c-tools: only try /dev/i2c/* if opening /dev/i2c-* fails with ENOENT
Trying to access /dev/i2c/* on every error after opening /dev/i2c-* can
mislead users who e.g. don't have root access. Instead of bailing-out
with "permission denied" we currently print "no such file or directory".
Fix it by trying open("/dev/i2c/%d") only if we got ENOENT.
Upstream i2cdetect tries to get any info it can from /sys and /proc even
when invoked by an unprivileged user, but we don't want to add unnecessary
bloat.
