* Fixed a typo in a comment * Refactored sig API following nist-branch (also fixes issue 380) * Fixed Windows compilation error in sig.c. * Added Picnic to Windows' config, and changed defaul alg to Picnic (since qTesla is not yet supported on Windows) * Moved sig_picnic and sig_qtesla under sig directory, to harmonize with kem api * Use different default sig alg on Windows to fix Travis back-compat tests and platform gap. * Further changes required for OQS to be properly used by applications * Compare OQS functions's return values to OQS error codes in sig.c. * Fixed typos in comments. * Replaced minimal_oqs_sig with example_sig. * Ensure travis tests fail on error * Add try-catch block in all-tests.sh * Ignore example_sig * Point global-namespace-check to .libs/liboqs.a * More precise error handling in global-namespace-check * Warning colours in travis tests and error handling in free-check * Error handling in style-check * Clean up style-check * Removed leftover minimal_sig_oqs ref and VS projects. * Prettyprint * Revert clang-format version check * Re-revert clang-format style check * Prettyprint * Added speed_sig to master. * Removed superfluous extern from sig schemes .h
