Decoding with aubinator encountered a command of 0xffffffff. With the
previous code, it caused aubinator to jump 255 + 2 dwords to start
decoding again.
Instead we can attempt to detect the known instruction formats. If the
format is not recognized, then we can advance just 1 dword.
v2:
* Update aubinator_error_decode
* Actually convert the length variable returned into a *signed* integer
in aubinator.c, intel_batchbuffer.c and aubinator_error_decode.c.

The call to gen_print_group should provide a pointer to the beginning
of the the structure data, not the start of the batch data.

This is pretty much the same tool as what i-g-t has, only with a more
fancy decoding of the instructions/registers. It also doesn't support
anything before gen4.
v2 (from Matt): Drop authors
Remove undefined automake variable
v3: Fix incorrect offsets for dword > 1 (Jordan)
v4: Fix decompression error with large blobs (Jordan)
