Add basic support for indirect functions. It allows providing a public

function symbol with an implementation choosen at run time.
Refactor calls to functions by address in ld.elf_so to create temporary
function descriptors on the stack, if the address is not leaked outside.
Limitations:
- no support for initialising static storage with function pointers
- no support for unnamed resolver functions
