f652340bec Problem: Could not allocate dynamic translator buffer

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

* Minor fixes ; forgot return type of clear_deleted_hooks ; do not declare variable in for predicate

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:
