a0001eea4c - speed up QgsSpatialRefSys after migration to OGR C-API: 
- create and destroy OGRSpatialReferenceH in constructor/destructor
  - move the PROJ.4 strings to OGR instead of a member variable and keep
    track its validity in mIsValidFlag.
  This reduces the need to allocate/deallocate of OGR structures and PROJ.4
  parsing and thereby speeds it up quite a bit.  Especially when on-the-fly
  projection is in use.
- collect common code of createFromSrid, createFromEpsg and createFromSrsId
  in the new loadFromDb method

NOTE: invalid PROJ.4 strings are now lost, I hope that doesn't break
      anything.
