Subject: [PATCH] Allow different type of pre-processing guards to be included
 in C headers.

This commit introduces the `c_include_guard_style` option, which can
take one of the following values: "ifdef", "pragma", "none". The
corresponding type of guard will be used accordingly to the value of
this variable.
