c94d3564c2 sendmail: from Vladimir:
Here comes the third part of compatibility patch for sendmail.
* Introduced new safe_getdomainname() -- will it be useful?
* Fixed SEGV if sender address is missed. Should snoop for sender address in mail headers?
* More compat: use HOSTNAME instead of HOST when no server is explicitly specified.
* crond: fixed mail recipient address.

21765fa063 udhcpc: kill undocumented -W, it was a no-op.
fix option parsing in the case some CONFIG_x are off.
 disable -b on NOMMU, make backgrounding work correctly
 (if a bit differently from MMU case). Previously,
 it wasn't working at all.
 stop using global data for flags in main(), opt
 bitfield works as well.

4ea83bf562 uclibc insists on having 70k static buffer for crypt.
For bbox it's not acceptable. Roll our own des and md5 crypt
implementation. Against older uclibc:

   text    data     bss     dec     hex filename
 759945     604    6684  767233   bb501 busybox_old
 759766     604    6684  767054   bb44e busybox_unstripped

so, we still save on code size.

e9b76e1f1e dnsd: fixes various segfaults.
One was a lib api change that was not updated and another
is a stack buffer overflow.
It also adds support for '*' in dnsd.conf. It resolves all hostnames to
a specific ip address. This is useful if you for example want redirect
all http traffic to your first-boot-web-wizard on you router/firewall.

518d8dd979 eliminated CONFIG_FEATURE_EDITING_FANCY_KEYS. the size savings
was small, compared to the total size of the command-line editing
features, and it removed key bindings that most wouldn't consider
"fancy", like ^U, and 'l' and 'h' in vi mode, ^F and ^B in emacs
mode.

84bbac5a09 enable use of ^V prefix to allow forced insertion of any character. in
particular, without this it's impossible to enter a TAB on the commandline
(whether tab completion is enabled or not).
