This series handles moving sandbox to the latest version of SDL, SDL2. It provides a few more features, better performance and has been around for long enough that it is present in distributions in the last several years.
Unfortunately it requires considerable rework of how memory allocation is handled in sandbox.
At present sandbox is built such that it uses U-Boot's malloc() instead of the C library's malloc. This mostly works but it is fragile, since any use of libraries can cause strange behaviour. For example SDL ends up calling U-Boot's malloc/free and this can confuse valgrind and even cause a crash in some cases.
The simplest solution seems to be to set a prefix for the allocation functions so that U-Boot's functions can co-exist with the C library's. This requires a little bit of fiddling but it guarantees that things work correctly in all circumstances.
We have got away with this for a long time partly due to the way that SDL1.2 operates on init. But with SDL2 this does not seem to be possible.
As a result of this series, malloc() is #defined to dlmalloc() within U-Boot (for sandbox only). The use of 'free' as a function in U-Boot is thus best avoided, since it is #defined to dlfree. The series updates some APIs to deal with this.
Changes in v2: - Update the name of the implementing callback function too - Drop the patch with the Roboto font - Fix 'adress' typo
