- Changed the behaviour of x509parse_parse_crt for permissive parsing. Now returns the number of 'failed certificates' instead of having a switch to enable it.

- As a consequence all error code that were positive were changed. A lot of MALLOC_FAILED and FILE_IO_ERROR error codes added for different modules.
 - Programs and tests were adapted accordingly
