62cf15d334 Several changes for size reduction (#929)
* Support CAPSTONE_STATIC with __GNUC__ compilers

* Allow custom export rules

* Make CAPSTONE_SHARED the default visibility option with GNUC (avoids behaviour changes)

* Reduce capstone static build size (mainly for kernel usage)

* Allow basic cs_detail support in diet mode

* Fixed valid_bnd unused function warning

* Do not disable cs_detail generation in CAPSTONE_DIET, use CAPSTONE_NO_DETAIL for that.

* Reverted CAPSTONE_NO_DETAIL at least until capstone supports more flexible configuration

* Added a missing endif

* Disallow custom export rules

7520fe5165 Kill a shadowed declaration of a local variable.
The variable tmp was already defined in the frame.
Redefining it makes some code linters grumpy.

298d413bbc * added a test file to suite for testing invalid and valid instruction sequences
* fixed and added a test for a thumb-2 invalid sequence that was incorrectly allowed before these changes (pop.w with sp argument included)
* fixed and added a test for a blx from thumb to ARM that had its immediate argument incorrect (misaligned)

* eliminated some warnings by explicitly casting so I could turn on
  treat warnings as errors locally

General notes:
*  probably worth turning on treat all warnings as errors in the msvc project files, had a subtle bug that resulted from a missing declaration causing differences in dll and static compilation modes

( code was working incorrectly in dll form because of missing declaration in arch/ARM/ARMMapping.h for new function ARM_blx_to_arm_mode. Something about the linking was confusing ld when making the dll, and the resulting offsets were wonky (e.g. the added ble test would show up as #0x1fc instead of #0x1fe like it should have )

* the invalid pop was being treated as a soft fail which then gets coerced
  to a success because it is != MCDisassembler_Fail in Thumb_getInstruction
  what are the semantics of a soft fail? Maybe we should be able to set up
  whether or not we want a soft fail to be a real fail in the csh struct?

027afdc179 Change the prototype of the callback in SKIPDATA option. Suggested by Ben Nagy.
Original prototype:
  typedef size_t (*cs_skipdata_cb_t)(const uint8_t *code, uint64_t offset, void* user_data);

Now we add @code_size argument to reflect the size of the input buffer @code.
Also, we change the data type of @offset to size_t because this argument indicates the
distance from currently examining bytes to @code, but not the address of the byte.

  typedef size_t (*cs_skipdata_cb_t)(const uint8_t *code, size_t code_size, size_t offset, void* user_data);
