Revert "libblkid: fix buffer usage in FAT prober"

This patch is unnecessary, the library uses two buffers and the VFAT
superblock is always stored in the probe->sbbuf buffer which is never
overwritten. It seems that FAT fsinfo is also in the superblock

build-sys: clean up gtk-doc stuff

  out-of-source build...

* gtk-doc expects that many generated files are stored in repository
  (we don't use XML templates, all documentation in source code only).

* we don't want to distribute generated html files, the docs is

stupid thing was released in u-l-ng 2.15 and 2.16 without any negative

It means the blkid from u-l-ng is not backwardly compatible with
the original version from e2fsprogs. The -L option has a different
meaning there.

swapon: handle <=linux-2.6.19 bug in /proc/swaps

Linux <=2.6.19 contained a bug in the /proc/swaps code where the header
would not be displayed (the first line).  Most people report the issue as
a sequence of swapon/swapoff calls to trigger, but for some lucky people,
it triggers all the time at initial boot.  Since this throws up an error,
init systems don't actually activate any swap files.

First, swapon shouldn't whine about unexpected format if the file is empty
(the default at boot).  This is easy to do by putting the warning behind a
check to ferror().

Second, we can detect that the first line isn't actually the header but
instead is a valid swap line and so need to be processed.  This assumes
that the first line will always be the same format.  Looking quickly at
older versions shows that this header has retained its exact format since
at least Linux 2.2.0 and considering the concern that goes along with proc
files and the ABI, it's highly unlikely it will ever change.
