Speed up of C-code bbfk.c by factor of 24%
avoiding for loops in get_timeshift,

speedup bbfk by another factor of 20%
Using on the fly generated sine table for sine and cosine calculation,
results in big speedup.
Adding note on optimization to changelog.
cleanup speedup for bbfk

* deallocating memory
* making sine_table optimization switchable by define
supporting mseed timing quality, C-code only

* reading timing quality with obspy-readbuffer
* writing etc. so far not supported
* 4 tests fail due to additional fields
making reading of timingquality optional

* adding missing header changes of last commit
* making readings of the timing quality optional
* all tests are passing again
Adding test for timing quality
pure refactoring

* using details instead of extra_info similar to
  msrutils line 753
Adding support to read calibration_type

* availability of calibration blockettes
  300, 310, 320, 390, 395 are stored as
  a single int8
* tests are passing, however --- no test
  data containing any calibration blockette
  is available in the obspy testdata
refactoring and doc

* renaming timingqual to timing_quality
* more precise documentation the details flag

deb packaging: replace old module packages

explicitely state that we replace all single module packages. this is
important if the deb packages were not installed via the metapackage
python-obspy. thanks @egdorf for the tip!
