Commit db169f2538 breaks the "ip -o link"
command, no output is displayed.. Fix by only excluding the link info if
in oneline mode and if the address family is not AF_PACKET.

On platforms that don't support SIGWINCH vi can be configured
with FEATURE_VI_USE_SIGNALS disabled and FEATURE_VI_WIN_RESIZE
enabled. This allows the user to force an update with ^L when
the screen is resized.
However, because the SIGWINCH handler hasn't run the virtual
screen buffer won't have been updated and the display becomes
corrupted. Fix this by calling new_screen() if necessary.

If the MANPATH environment variable isn't set a provisional default
path of /usr/man is placed in man_path_list. This is only used if a
configuration file doesn't contain an alternative path.
If a configuration file lists the default path first:
MANPATH /usr/man:/usr/share/man
add_MANPATH() sees that the default entry is already present and skips
it. As a result man_path_list only contains the second and subsequent
components of the configured MANPATH.
In such cases the path should not be skipped.

Currently, running "udhcpc -n -b" causes udhcpc to go to background and
then exit after some time unless a lease is obtained.
It's not very useful to do so
as the calling process doesn't know
if the lease was obtained or not anyway.
The code actually tries to favor "-b" over "-n",
but doesn't clear "-n" flag while clearing "-b" after backgrounding.
So, clear "-n" flag after going into background.
This effectively makes "-b" override "-n" completely
and "-n -b" behave the same as "-b".
This allows to override default "-n" option, passed to udhcpc by ifupdown,
without recompiling busybox.

The following constructs result in ever-increasing memory usage:
while true; do { true; } </dev/null; done
while true; do ( true; ) </dev/null; done
For comparison, bash displays static memory usage in both cases.
This has been fixed in dash by commit 2bc6caa. The maintainer
writes:
I have simplified evaltree so that it simply sets the stack mark
unconditionally. This allows us to remove the stack marks in the
functions called by evaltree.
Closes BusyBox bug 7748.

Commit bb983f30e (vi: fix faulty undo after autoinsert) has a
number of problems:
- The commit message refers to 'autoinsert' when it really means
'autoindent'.
- The indentation of undo_push_insert() was incorrect.
- Most seriously the commit only fixed the problem for cases where
the indentation was exactly one character. This is because undo_push()
only allows single characters to be queued for UNDO_INS_QUEUED.
Lifting this restriction allows the example given in the previous
commit message (with a three character indent) to work.

Currently if the 'r' command is followed by a carriage return a
literal CR replaces the current character.
Fix this so that:
- a new line is inserted
- the autoindent setting is respected
- the cursor is placed at the start of the new line

Enable autoinsert and enter the following with an indent of three
spaces:
line 1
line 2
Using 'u' to undo the last insert results in:
line1e 2
The insertion of the indent hasn't been properly recorded.
Since recording insertions is a common operation add a convenience
function, undo_push_insert(), to handle this and use it to record
the autoindent correctly.

fdisk, hexedit and ed calls read_line_edit in libbb/lineedit.c with NULL
as first argument. On line 2373 of lineedit.c of busybox version 1.29.3,
state->hist_file is referenced without checking the state->flag.
This causes segmentation fault on fdisk, hexedit and ed on ARM Cortex-A9.
It somehow works on x86_64.
