Use astyle(1) to make style consistent

[smortex]

This was discussed in #53 (link to comment).

When this pull request is approved, I will, before merging I will:

• Rebase branch on top of master;
• Run make style and add changes to this branch.

Maybe take the chance to align style between libnfc and libfreefare?
At the moment libnfc style is:

astyle --formatted --mode=c --suffix=none \
--indent=spaces=2 --indent-switches --indent-preprocessor \
--keep-one-line-blocks --max-instatement-indent=60 \
--style=linux --pad-oper --unpad-paren --pad-header \
--align-pointer=name {} \;

Huhu, in fact I conscientiously used settings that match FreeBSD's style(9) since it's basically what I used when writing libfreefare.

The only difference these flags produce with the current code is that I used a space before an opening parenthesis when calling a function (when I did not forget it, bad habit I took from mono's code), and it's not possible to have this exact behavior with astyle. This leads to quite a lot of changes, but I am OK with it. However, changing all indentation rules seems gratuitous to me.

Do you think it's better to have a similar style in libnfc and libfreefare ?

Not that important if it makes more trouble than benefits, forget about it

Fsck, committing the result of make style dismissed the review approval 😮
