Android debugger

The Android debugger has the following particularities and limitations:

- ARM32, AArch64, x86 and x64 Android native debugging is supported

- Both ARM and Thumb mode code is supported

- Multithreaded applications can be debugged. However, since the operating system does not report thread deaths, they are reported only when the debugger notices that the thread is missing (for example, because there is an error when we try to suspend it)

- Apparently Android reports applications that are currently executing a system call as executing "LDMFD SP!, {R4,R7}" before the syscall. Once the syscall completes, the next instruction is reached.

- Hardware breakpoints for ARM32 and AArch64 are not supported.
