API changes

In this section, we describe the changes done to the API. These include new functions, modified functions and structures, etc.

Action	What to look for
`OSQPInfo`	The fields of `OSQPInfo` were changed.
`OSQPSettings`	The fields of `OSQPSettings` were changed..
`OSQPSolver`	`OSQPSolver` now holds all the information previously stored at `OSQPWorkspace` (`OSQPInfo`, `OSQPSettings`, `OSQPInformation`, and `OSQPWorkspace`).
`osqp_cleanup`	`osqp_cleanup` now gets `OSQPSolver` instead of `OSQPWorkspace`.
`OSQPCscMatrix`	CSC matrices are stored in `OSQPCscMatrix`, and are updated with `csc_set_data`.
`osqp_setup`	The function `osqp_setup` and its signature changed.
`l,u,q`	The vectors `l,u,q` are updated via `osqp_update_vec` (which replaces `osqp_update_lin_cost` and `osqp_update_bounds`).
`osqp_update_data_mat`	All of the fields of a data matrix are updated with `osqp_update_data_mat` (which replaces `osqp_update_lower_bound`, `osqp_update_upper_bound`, `osqp_update_P_A`, `osqp_update_P`, and `osqp_update_A`).
`osqp_warm_start`	The function `osqp_warm_start` replaces `osqp_warm_start_x` and `osqp_warm_start_y`.
`osqp_solve`	`osqp_solve` now gets `OSQPSolver*`.

The following types and variables were renamed.

Action	What to look for
`polishing`	Changed `polish` to `polishing` in `OSQPSettings`.
`warn_starting`	Changed `warm_start` to `warm_starting` in `OSQPSettings`.
`OSQPInt`	`OSQPInt` replaces `c_int`.
`OSQPFloat`	`OSQPFloat` replacees `c_float`.

The following values were cahnged.

Action	What to look for
`OSQP_TIME_LIMIT`	The default time of `OSQP_TIME_LIMIT` is now 1e10.
`enum osqp_linsys_solver_type`	The possbible values changed from `QDLDL_SOLVER,MKL_PARDISO_SOLVER` to `OSQP_UNKNOWN_SOLVER,OSQP_DIRECT_SOLVER,OSQP_INDIRECT_SOLVER`.
