Split i2cdump_main() into shorter functions. Simplify the code a bit.
Make block an array of ints so that we can store negative results of
read functions (fixes a bug found by Denys Vlasenko).

Addresses 0x00-0x02 shouldn't be scanned by default. This patch makes
'first' default to 0x03 and only enables lower addresses if '-a' option
is passed

We can't use i2c_set_slave_addr() in i2cdetect, as we have to check for
EBUSY after calling ioctl(I2C_SLAVE) and print 'UU' on busy addresses
instead of bailing-out.
While we're at it: reorder definitions of local vars in i2cdetect_main().

Additionally, open(2) failures do not make the program die immediately.
This makes the behavior of the program match coreutils more closely.

The commit
ash: move parse-time quote flag detection to run-time
breaks pattern substitution in parameter expansion. Fix this and
revise the code so that the different handling of the pattern and
the replacement string takes place in rmescapes rather than the
separate function parse_sub_pattern.

Because the parser does not recursively parse parameter expansion
with respect to quotes, we can't accurately determine quote status at
parse time. This patch works around this by moving the quote detection
to run-time where we do interpret it recursively.
Test case:
foo=\\ echo "<${foo#[\\]}>"
Old result:
<\>
New result:
<>
Do not quote back slashes in parameter expansions outside quotes.
Test case:
a=/b/c/*
b=\\
echo ${a%$b*}
Old result:
/b/c/*
New result:
/b/c/

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.

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.

Regression added in commit 14158b4127dba30466c50147b868a6a89702960b
"find: add optional support for '-exec ... {} +'"
This commit causes find to exit on the first path argument that was not
found, which breaks existing scripts and is incompatible to other
implementations.
Instead of exiting on the first failure, return EXIT_FAILURE at the end
if any error occurred.
