* llama : return nullptr from llama_grammar_init This commit updates llama_grammar_init to return nullptr instead of throwing an exception. The motivation for this is that this function is declared inside an extern "C" block and is intended/may be used from C code which will not be able to handle exceptions thrown, and results in undefined behavior. On Windows and using MSVC the following warning is currently generated: ```console C:\llama.cpp\llama.cpp(13998,1): warning C4297: 'llama_grammar_init': function assumed not to throw an exception but does C:\llama.cpp\llama.cpp(13998,1): message : __declspec(nothrow), throw(), noexcept(true), or noexcept was specified on the function ``` Signed-off-by: Daniel Bevenius <daniel.bevenius@gmail.com> * squash! llama : return nullptr from llama_grammar_init Add checks for nullptr when calling llama_grammar_init.
