Support building on Android arm aarch64 x86 x86_64 
1. Add cmake support in CMakeLists.txt according to https://developer.android.com/ndk/guides/other_build_systems

2. Resolve symbols errors

3. Backport fixes from 438ed42311

   > QEMU relies on two optimization for ppc64 and arm:
   >
   > 1. if(0) /* optimized code */
   > 2. assert(0); /* optimized code */
   >
   > But the assert on mingw32 doesn't have noreturn attribute which prevents

   > to fit in the first optimization.
   >
   > The assert implementation is copied from glib as qemu did.

   Unfortunately, NDK also doesn't have an assert implementation qemu prefers.

Fix wrong sync after UC_ERR_[READ, WRITE, FETCH]_[UNMAPPED, PROT] (#1368) 
* Fix wrong sync after UC_ERR_[READ, WRITE, FETCH]_[UNMAPPED, PROT]

Note that:
1. We only guarantee the pc (and other internal states) is correct
if and only of `uc_emu_start` returns without any error (or errors
have been handled in callbacks.).
2. If memory read/write error isn't handled by hooks, the state is
undefined and the pc is probably wrong if no hook is installed.

This fixes #1323.

* Rename variables

* Add note in unicorn.h

* Refine test_i386_invalid_mem_read_in_tb

Fix block hooks being called twice after an early exit from execution. (#1194) 
Ensure the TCG exit flag is cleared at the end of cpu_exec. This ensures
that subsequent calls are not polluted by the prior call to request an
early exit. The symptoms of the problem being addressed here are that
after a cpu_exit call triggered within a hook there may still be a
pending tcg_exit_req flag set. This then causes a block to start its
execution and then be aborted (from which point it'll continue because
there's no other condition to service). The start of the execution
causes the block hook to be called, no actual code to be run, and then
the block started again with another block hook call.

This change is discussed in ticket 1193:

99097cab4c Add implementation of access to the ARM SPSR register. (#1178) 
The SPSR register is named within the Unicorn headers, but the code
to access it is absent. This means that it will always read as 0 and
ignore writes. This makes it harder to work with changes in processor
mode, as the usual way to return from a CPU exception is a
`MOVS pc, lr` for undefined instructions or `SUBS pc, lr, #4`
for most other aborts - which implicitly restores the CPSR from SPSR.

This change adds the access to the SPSR so that it can be read and
written as the caller might expect.

b59632fb64 Ensure that PC is not fixed up when code tracing or timing. (#1179) 
Under some circumstances, the PC is not fixed up properly when
returning from the execution of a block in cpu_tb_exec. This appears
to be caused by the resetting of the PC from the tb.

This change removes the additional fixup in the cases where there
is code tracing or timing active. Either of these cases would result
in the wrong PC being reported.

Closes unicorn-engine#1105.

02e6c14e12 x86: add MSR API via reg API (#755) 
Writing / reading to model specific registers should be as easy as
calling a function, it's a bit stupid to write shell code and run them
just to write/read to a MSR, and even worse, you need more than just a
shellcode to read...

So, add a special register ID called UC_X86_REG_MSR, which should be
passed to uc_reg_write()/uc_reg_read() as the register ID, and then a
data structure which is uc_x86_msr (12 bytes), as the value (always), where:
	Byte	Value		Size
	0	MSR ID		4
	4       MSR val		8
