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

Catena cyber feb46abb4a Fuzz (#1000) 
* Integration with oss-fuzz

* Use CFLAGS even for linking

as for fuzzing with asan

* Do not abort on uc_emu_start error

* Redirect fuzz output somewhere else than stdout

* Use uc_open for every fuzz instance

* Avoids timeouts from infinite loops

Limiting the number of instructions

* Moving fuzz to tests directory

zhangwm 4a62409949 arm64eb: arm64 big endian also using little endian instructions. (#816) 
* arm64eb: arm64 big endian also using little endian instructions.

* arm64: using another example that depends on endians.

example:
1. store a word: 0x12345678
2. load a byte:
   * little endian : 0x78
   * big endian    : 0x12
