Joan fixes

Angel look at a number of fixes that I had to apply to compile on my mac:

1. Struct for params were forward-declared also as class inside the pointers macros. Changed called macro.

2. parameter const InputArray& was not accepted (const qualifyer has no effect type of error). Noticed InputArray is already defined const in a typedef. Removed const qualifyer.

3. Some minor bugs in quich_harris (unused variable)

4. I could not pass the following ctests (possibly they require files that I don't have):

gtest_trifocaltensor gtest_detectors gtest_matchers

Please check that all is OK.
