c919d561ad umount: always use umount2 syscall with specified flags
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'

ca25af9b06 ash: fix slash treatment in expmeta
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.

65c501a093 ifupdown: 'prio' should have been 'metric' in static_up and static_up6
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.

26ccd3d062 less: fix botched attempt to use last column
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.

64ed5f0d3c uname: make OS name configurable
A mailing list thread in September 2013 discussed changing the string
returned by the non-POSIX 'uname -o' option.  Nothing ever came of this
because there was no agreement as to what the string should be.

Make the string configurable so that people can decide for themselves.

b27cf31003 less: further tweaks to regular file detection
Test explicitly for REOPEN flags:  update_num_lines is called
unconditionally so (num_lines != NOT_REGULAR_FILE) is also true when
num_lines contains a valid number of lines.

The call to fstat doesn't need to be in #if ENABLE_FEATURE_LESS_FLAGS:
the whole function is already in such a test.

1ecb996fd2 less: allow use of last column of terminal
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.

d542d183e1 less: fix line number confusion
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.

670c3f7822 echo: make escape sequences depend on fancy mode
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.

52f2f37477 fbset: fix rgba parsing
In commit b5c7220e7b
"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.

193ba408a4 less: improvements to verbose status messages
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.

Fixes Bug 7586
