sendmail: use host rather than NIS domain name for HELO

According to RFC 5321 the argument to HELO "contains the fully-qualified
domain name of the SMTP client" or its IP address if no FQDN is available.
BusyBox sendmail uses the NIS domain name instead which, in many cases,
is likely to be the default "(none)". [vda: yes, I checked my machine
and its uts.domainname was indeed "(none)"]

Using the host name is more likely to satisfy the intent of the RFC while
allowing the otherwise unused safe_getdomainname function to be removed.

lineedit: histfile can get emptied when CONFIG_FEATURE_EDITING_SAVE_ON_EXIT=y

When CONFIG_FEATURE_EDITING_SAVE_ON_EXIT is set to y, the histfile
will get cleared if the total amount of history lines is less than MAX_HISTORY.
Only if the histfile is not empty _and_ the amount of lines currently
in memory are equal to or greater than MAX_HISTORY, history saving will
work as expected with this feature enabled.

Output from defconfig + CONFIG_FEATURE_EDITING_SAVE_ON_EXIT=y:
$ echo "foo" > ~/.ash_history
$ ./busybox ash
~/busybox/a $ echo "bar" > /dev/null

Make unix (local) sockets work without IPv6 enabled

The xsocket_type() function had an optional "family" argument
that was enabled only if IPv6 is enabled. In the case of the
function was called with a valid AF_UNIX argument, and IPv6 is
disabled, this argument was silently ignored.

This patch makes the "family" argument mandatory, while keeping
the old behavior i.e., if AF_UNSPEC is passed, we try first IPv6
(if it's enabled) and fallback to IPv4.

Also I changed all callers of xsocket_type() to reflect its new
interface.

cttyhack: handle multiple consoles found in sysfs

If multiple consoles are found from the sysfs file, cttyhack fails:

cttyhack: can't open '/dev/tty0 ttyS0': No such file or directory

In such cases take the last one as the kernel will use that one for
/dev/console.

httpd: fix sendfile of files larger than 2 Gb. Closes 4754

When built with "sendfile" support, httpd was unable to send large files
(>2 GB) in one single connection, terminating it before the full file
has been sent.
