redefine vsprintf in a nice way

[nicola-lunghi]

Hi,

first, thank you for this project is really nice!!!!

I have a couple of questions:

1. there's a "nice way" without changing the ctest.h header to redefine the vsnprintf function?
   in my system I have to use a specific test_msg() function (for various reasons) to report text messages to the system so I cannot use any "printf" function. how can I extend ctest to use custom printf functions?

2. Also I have another function test_results() to report results to the main test framework.
   there's a way to call a user function to report test results for the single test? how will you handle this?

3. how can I define different test suites and skip/execute those depending on a "configuration":

for example I can have

suite1
suite2
suite3

configuration1 -> execute 1, skip 2 and 3
configuration2 -> execute 1, skip 2 execute 3
configuration3 -> execute 1, 2 and 3

switch(test_configuration)
case NO_STRESS_TEST
result = ctest_main(configuration1)
case TEST_ALL
result = ctest_main(configuration3)

There is no real nice way. There is a CTEST_SKIP() version that skips tests, but you would have to wrap that in macros of your own..
