Bug 710818 - Overflow safe wrappers for acos/asin (now really)

acos() and asin() are only defined in a certain range. Implement some
range/overflow safe wrappers rather than potentially passing infinite
to other modules (e.g. cairo did assert() on it.)

Additionally check for !isinf() in cairo plug-in (should not trigger
anymore).
[warningectomy] unused variable
[warningectomy] control reaches end of non-void function
database: remove unnecessary extern declarations
[unit test] Initial version of dia-svg test
cleanup: remove stale prototypes from headers

Probably some of these never had an implementation, but they all
have none right now.
Bug 726458 - Fix build problem on FreeBSD

Define _BSD_SOURCE does not make fchmod() available on FreeBSD. Change
_POSIX_C_SOURCE to 200809L so we can build it on FreeBSD.
