8f4faa1e3d df: use f_frsize instead of f_bsize for correct sizes 
Use the correct field f_frsize instead of f_bsize.

The statfs f_bsize is the "Optimal transfer block size" while the
f_frsize is the "Fragment size (since Linux 2.6)". On some FUSE
filesystems those may differ.

Fixes bug 9046

ea351b9742 ls: fix columnar output. Closes 8731 
In coreutils/ls.c, 1.19 introduced commit
2f7d9e8903, removing the variable tabstops and
hard coding the column separation to 2 characters, but was not done correctly.
The column_width assumes a gap of 1 character, so the computed number of
columns exceeds the terminal width when many small files are encountered.

A minor problem but surprisingly annoying.

6a70db85cf truncate: use O_WRONLY|O_NONBLOCK 
This matches coreutils behavior.  We don't read the fd, and truncation
does not need blocking.

Fix this by simply always setting the mode, as it doesn't hurt even
when O_CREAT is not specified.

This bug is a regression introduced in fc3e40e, as xopen(), which
was originally used, would automatically set the mode.

invarg_1_to_2(a,b) is somewhat easier to read: "invalid argument 'a' to 'b'"

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.

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.

fc3e40ee81 truncate: do not die when a file doesn't exist and no-create flag is on 
Additionally, open(2) failures do not make the program die immediately.
This makes the behavior of the program match coreutils more closely.
