7b7cb1ecc9 deprecate fclose() and introduce VIR_{FORCE_}FCLOSE()
Similarly to deprecating close(), I am now deprecating fclose() and
introduce VIR_FORCE_FCLOSE() and VIR_FCLOSE(). Also, fdopen() is replaced with
VIR_FDOPEN().

Most of the files are opened in read-only mode, so usage of
VIR_FORCE_CLOSE() seemed appropriate. Others that are opened in write
mode already had the fclose()<  0 check and I converted those to
VIR_FCLOSE()<  0.

I did not find occurrences of possible double-closed files on the way.

f04de501bc Introduce VIR_CLOSE to be used rather than close()
Since bugs due to double-closed file descriptors are difficult to track down in a multi-threaded system, I am introducing the VIR_CLOSE(fd) macro to help avoid mistakes here.

There are lots of places where close() is being used. In this patch I am only cleaning up usage of close() in src/conf where the problems were.

I also dare to declare close() as being deprecated in libvirt code base (HACKING).

44258473b8 docs: hacking: explain why using curly braces well is important
* docs/hacking.html.in: Use the "curly braces" section from coreutils'
HACKING, adapting for libvirt's different formatting style.
* HACKING: Sync from the above, still mostly manually.
