Simplify Detour API

[rdbo]

Instead of having LM_MakeTrampoline, LM_DestroyTrampoline, etc, what could be done is have a single LM_Detour function that has a parameter which would be the pointer to a trampoline. If that pointer is not null, generate the trampoline. If it is null, don't do anything.
Prototype:

LM_API lm_size_t
LM_Detour(lm_address_t src, lm_address_t dst, lm_address_t *ptrampoline);

LM_API lm_bool_t
LM_RestoreDetour(lm_address_t ptrampoline, lm_size_t size);
