API improvement proposal: OCP QP size as an array of structs

1

Numerous hpipm functions take the arguments that define a size of an OCP QP, for example: ```c int d_memsize_ocp_qp(int N, int *nx, int *nu, int *nb, int *ng, int *ns);...

After taking 584 iterations `solve_ocp_qp_ipm()` returns a solution containing NaNs. **The return code is nevertheless 0, which indicates success**. The failed QP im MATLAB format: [failed_qp.txt](https://github.com/giaf/hpipm/files/1387729/failed_qp.txt). Take into account that...

Please document the return codes of the `*solve*()` functions.

Similarly to #4 and #3 , I propose ```c struct ocp_qp_stage_sol { double *u; double *x; double *ls; double *us; double *pi; double *lam_lb; double *lam_ub; double *lam_lg; double *lam_ug;...

Similarly to #3, elements of an OCP QP create the same difficulties, to even bigger extent. They can also be conveniently united in a struct: ```c struct ocp_qp_stage { double...

Several improvements have been made, here are the main ones: * RAII-based subscription management * Return codes replaced by exception-based error handling in many places * Interfaces of `RWSClient` and...

Feature request: make the .uxf-files easier to merge

1

Currently it is difficult to automatically merge .uxf files, as well as to manually resolve conflicts. One of the reasons for this is that XML tags in .uxf files are...

[Type-parameterized tests](https://github.com/google/googletest/blob/master/googletest/docs/advanced.md#type-parameterized-tests) seem to be surrently not supported. Although shown in the tree view, they are not executed together with normal tests. Neither can they be debugged or navigated to....
