Change the build process for EPT such that IDs are used in cross-compartment calls instead of function pointers. This is necessary to restrict control flow of cross-compartment calls to actual function boundaries instead of arbitrary pointers. Also make the maximum number of threads supported by the EPT backend configurable. Signed-off-by: Sebastian Rauch <[email protected]>
