Use of global variables about unicorn

[JonathonReinhart]

#22 will take care of a couple of these.

[aquynh]

some of these variables (map_*) are confirmed issue, and some of them are explained in #21.

thanks.

It gets worse. In the qemu target-specific code, there are places where a global first_cpu is referenced. Example:

void x86_reg_reset(uch handle)
{
    struct uc_struct *uc = (struct uc_struct *) handle;
    CPUArchState *env;

    env = first_cpu->env_ptr;     // <-----
    ...

[aquynh]

no, first_cpu is not a global variable if you look closer at its definition.

map_begin, map_end, and map_count are taken care of at this point

[aquynh]

all fixed, thanks.
