bc572be472 Check for TLB invalidation after read callback(s). (#1122)
* Adding regression test for issue where writing memory into a read only segment during a access callback fails.

* Check for TLB invalidation when calling read callbacks;  Writes to read-only memory by the callback cause a TLB flush which requires a re-read of the TLB.

12bcf3bea0 Fuzz builds ok (#1007)
* Fuzzing M68K without abort

* UC_MODE_32 is not ok with sparc

use UC_MODE_SPARC32|UC_MODE_BIG_ENDIAN instead

* Temporary removing leaking on start targets

* Do not abort for m68K undef instructions

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

0f14c47344 Makes SYSENTER hookable again on x86 (#996)
Adds SYSENTER to the whitelist of supported hookable instructions in unicorn
as well as fixes up the existing sysenter_hook_x86 regression test which was
previously failing

47150b6df3 reg_read and reg_write now work with registers W0 through W30 in Aarch64 (#716)
* reg_read and reg_write now work with registers W0 through W30 in Aarch64 emulaton

* Added a regress test for the ARM64 reg_read and reg_write on 32-bit registers (W0-W30)
Added a new macro in uc_priv.h (WRITE_DWORD_TO_QWORD), in order to write to the lower 32 bits of a 64 bit value without overwriting the whole value when using reg_write

* Fixed WRITE_DWORD macro

reg_write would zero out the high order bits when writing to 32 bit registers

e.g. uc.reg_write(UC_X86_REG_EAX, 0) would also set register RAX to zero

bc08bfda67 Unit testing in CI (#651)
- in appveyor, install clang and cmake in cygwin, enable package upgrades, and build cmocka and enable testing for gcc only
- in `gitignore`, ignore generated cmocka folder
- in travis, use brew in osx to install cmocka, and enable testing for gcc and clang on os x and linux
- in `Makefile`, change to use `uname -s` to determine os type
- make `install-cmocka-linux.sh`, a simple shell script to download and install cmocka on linux
- in `bindings/Makefile`, enable `make -c` to call subdirectory makefiles instead of `cd [dir] && make` and include environment variables for runtime access to generated libraries
- in `samples/Makefile`, change to use `uname -s` to determine os type, remove `clean_bins` from `all` command, and include `Werror` for compile strictness
- in `tests/unit/Makefile`, add `cflags` for compile time access to cmocka headers and library, include execute vars for runtime access to cmocka and unicorn libs
- in `tests/unit/test_tb_x86.c`, comment out assert that would not compile
