* Fix vm_remap, of trouble with which the previous diagnosis was completely ↵comex2015-02-231-10/+12
| | | | | | | | | | | incorrect. It's actually the fact that no vm_map_server actually exists on the kernel side - even though the otherwise useless function vm_remap exists in the kernel source, and mig generates server code for it, apparently that server code isn't built or linked into the kobject table. Bizarre. Anyway, switch to mach_vm_remap, which is what vm_remap in userspace calls into.

* Fix hook-function:comex2015-02-189-311/+466
| | | | | | | | | | - Thread stoppage is now complemented by sigaction to catch injected threads (sigaction is not used exclusively because the rest of the program could be trying to use sigaction itself in the meantime - this is a real thing, ask Dolphin) - mprotect is no longer used due to max_protection possibly getting in the way; instead, a copy is created and mapped onto the original.

* Trampoline fixes.comex2015-02-1410-48/+86
| | | | | | | | | | | | | The transformed code was incorrect because it assumed the pointer it was writing to was where the code would execute, but it was actually 'rewritten_temp'. Changed transform_dis_main to take a pc_trampoline pointer, which also helps the test harness. However, this means that it has to be called after the trampoline has been allocated, while before the trampoline allocation depended on the generated size; this change doesn't bother to use two passes or anything, but just allocates a new code buffer if the maximum possible size isn't available - not the end of the world, since trampoline_ptr will still only be increased by the actual size before the next hook in the series (if any).

* Refactor disassembly so x86 works, and add x86 transform-dis.comex2015-02-0820-197/+298
| | | | | | | | | | This patch is a monolithic mess, because I was too lazy to do the refactor first (that would require some stash fun, since I wasn't actually sure before doing x86 transform-dis what would be needed). Anyway, the resulting code should be cleaner - less duplication. This breaks ARM/ARM64.
