Changes
Currently the RPC error throws a cryptic-looking error if the remote side crashes because the generic
GGML_ASSERTmacro is used.This PR just adds a simple, RPC-server-specific macro that has the same behavior as
GGML_ASSERTbut prints a slightly nicer message.Note that the error message assumes that the only reason an invalid
statuswould be returned is a RPC server crash or malformed payload. I'm happy to change the message if there are other edge-cases we want to cover.Before:

Testing
Tested by specifying only the
-ctk q4_0flag (without-ctv q4_0and withoutGGML_CUDA_FA_ALL_QUANTS) and running an example prompt.Accidentally omitting this flag and getting the cryptic error is what motivated this PR.
