lock -n is similiar to flock -n. If the lock was already taken,
fail with exit code = 1 and write error message to stderr.
example:
if ! lock -n /tmp/foo ; then
echo lock exits.
else
echo lock was free. But is locked now.
fi
> lock was free. But is locked now.
> lock exists.

Note, that licensing stuff is a nightmare: many packages does not clearly
state their licenses, and often multiple source files are simply copied
together - each with different licensing information in the file headers.
I tried hard to ensure, that the license information extracted into the OpenWRT's
makefiles fit the "spirit" of the packages, e.g. such small packages which
come without a dedicated source archive "inherites" the OpenWRT's own license
in my opinion.
However, I can not garantee that I always picked the correct information
and/or did not miss license information.

Currently busybox utils like "ls" fail to display filenames containing UTF-8
characters, replacing any special characters with "?".
Change libbb's printable_string() function to allow high ASCII characters so
that unicode filenames are displayed correctls.

somebody started to set a function returncode in the validation
stuff and everybody copies it, e.g.
myfunction()
{
fire_command
return $?
}
a function automatically returns with the last returncode,
so we can safely remove the command 'return $?'. reference:
http://tldp.org/LDP/abs/html/exit-status.html
"The last command executed in the function or script determines the exit status."

Patch sets the source IP address of DHCP request messages during rebind to the IP address
assigned to the udhcpc client. Source address 0.0.0.0 can only be used by a client prior
to obtaining its IP address (see RFC2131 § 4.1). Source IP address behavior lines up now with
the ISC dhcp client implementation for DHCP request messages during rebind and DHCP release
messages.

Some boards have the WLAN EEPROM stored in flash in big-endian format,
whereas the driver requires the EEPROM in little-endian format. The
conv=swab option in dd is particularly useful in this case. This patch
backports this feature from busybox-1.22 based on the following commits:
commit b941316ae5313be523b64f0a9151ee4decb2b35b dd: support conv=swab
commit 8395bd3f52f8ed46fa3ffc316b2d113afa748bae dd: fix example in a
comment. No code changes.
commit 5b9910f0a4a1b7976c46e6f849aaa263180e5521 dd: fail if swab is
attempted on odd-sized block

Minor fix to existing patch which did not correctly implement -n support for the export command in ash. The VEXPORT flag of a variable was set in the first call to setvareq() and then remained set in the subsequent call, because the variable already existed in the environment.
Although /lib/functions.sh by default does not export variables (NO_EXPORT=1), this issue was leading to dirty environments.
Without this fix:
(ash) export A=1; export -n B=2; /bin/ash -c "echo \$A, \$B"
1, 2
With this fix:
(ash) export A=1; export -n B=2; /bin/ash -c "echo \$A, \$B"
