Make umount -f more compatible with util-linux 2.22.2.
Before:
* 'umount -f': calls umount syscall,
if it fails calls umount2 with 'MNT_FORCE'
* 'mount -f -l': calls umount syscall,
if it fails calls umount2 with 'MNT_LAZY'. 'MNT_FORCE' dropped
After:
* 'umount -f': calls umount2 syscall with 'MNT_FORCE'
* 'mount -f -l': calls umount2 syscall with 'MNT_LAZY' and 'MNT_FORCE'

Commit 549deab caused this sequence of commands:
mkdir foo
cd foo
touch a b
echo "./"*
to return './*' instead of the expected './a ./b'. The problem
was caused by the backport of commit 880d952 from dash. In dash
the issue was fixed by two further commits by Herbert Xu:
<d6d06ff> [EXPAND] Fixed non-leading slash treatment in expmeta
<36f0fa8> [EXPAND] Fix slash treatment in expmeta
(See git://git.kernel.org/pub/scm/utils/dash/dash.git)
Apply these fixes to BusyBox ash, thus causing the new test
glob3.tests to succeed.

When a static interface with explicit gateway and metric in /etc/network/interfaces
is enabled using 'ifup', and further, the BusyBox 'ip' applet is enabled, the
following error message appears at the console (and no default route is added):
ip: either "to" is duplicate, or "prio" is garbage
Tracing ifup reveals that it is attempting to run the following shell command:
ip route add default via <GW> dev <DEVICE> prio <METRIC>
'ip' does not understand the 'prio' argument, causing this error. With 'metric',
it works fine.

added to the list by llist_add_to_end(), which allocates the llist_t

Commit 1ecb996 attempted to make read_lines() use the last column of
the terminal (as re_wrap() did). There were two problems with this:
- The size of the buffer allocated for lines wasn't increased to allow
for the extra character.
- The test for width overflow was moved after the point where the
next character was added to the buffer. This caused a buffer overflow
in certain circumstances.
For example, if the line beyond the end of the display was wider than
the display read_lines() would initially read the partial line into a
buffer. When the user moved down read_lines() would be called again
to ensure the rest of the line was read. This would place the next
character in the partial line before checking for overflow.
This can be fixed by moving the test for overflow back to where it was
before commit 1ecb996 and changing the comparison to `>` rather than
`>=`.
There are two other places where buffers are created without allowing
for width+1 characters.

unconditionally so (num_lines != NOT_REGULAR_FILE) is also true when

When read_lines tests whether a character will fit on the current
line it checks the *next* character but in case of overflow doesn't
display the *current* one. This results in the last column of the
terminal never being used.
The test in re_wrap (used when the terminal width changes or line
numbers are enabled/disabled) is different: it does allow the use
of the final column.

Much of the code refers to lines using indices into the flines
array (which splits lines into portions that fit on the terminal).
In some cases this is wrong and actual line numbers should be
used:
- when lines are being truncated rather than wrapped (-S flag)
- when line numbers have been entered by the user
Also fix a bug in numeric input and improve the display at EOF.

Move the code to detect non-regular files to the point where the
file is being opened. If num_lines == READING_FILE guarantees
that the file is regular.
Detect when a file becomes unreadable between it first being opened
and the call to update_num_lines. Mark the file as being non-regular
so we don't try that again.

Currently when you disable fancy echo, escape sequences are hardcoded
enabled (e.g. as if you used `echo -e` all the time). The opposite
behavior is more desirable (always disable -e support) because:
* This seems to contradict the spirit of the kconfig help text (where
it says enable support for -n/-e flags), although you could say that
we aren't supporting the -e flag directly as `echo -e` will show the
-e flag.
* POSIX makes escape sequences optional, and even says they are there
only on XSI-conformant systems.
* It saves space (~100 bytes on x86_64).
* It makes things faster!
* It makes it behave more like bash where you need an explicit -e flag
in order for escape sequences to be interpreted.

In commit b5c7220e7b2b6611fe5beca494c67bfe51fcfafb
"fbset: respect rgba configuration lines in fb.modes"
I somehow managed to swap the offset/length markers around.
The man page for fb.modes says it should be offset/length
not length/offset as I was accidentally parsing it.
As my fb.modes file was also reversed I didn't notice
until I tried someone elses fb.modes file. Mea culpa.

Make verbose status messages (-m/-M flags) behave more like the
real `less` command:
- fix display of line numbers so they're correct whether lines are
being truncated (-S flag) or wrapped.
- don't display total lines or percentage when lines are read from
stdin: we don't have that information until we reach EOF. When
we do reach EOF the additional information is displayed.
- when lines are read from a file count the total number of lines
so that we can display percentages. Counting lines is avoided
until the information is actually needed. If the user pages to
EOF the separate read pass can be avoided entirely.
