55be6653e0 intel: gen-decoder: fix xml parser leak
In the unlikely case the parsing of genxml files fails, we were
leaking an xml parser object.

We should get either 0 or 1 here.

1ea41163eb intel/aubinator: Correctly read variable length structs.
Before this commit, when a group with count="0" is found, only one field
is added to the struct representing the instruction. This causes only
one entry to be printed by aubinator, for variable length groups.

With this commit we "detect" that there's a variable length group
(count="0") and store the offset of the last entry added to the struct
when reading the xml. When finally reading the aubdump file, we check
the size of the group and whether we have variable number of elements,
and in that case, reuse the last field to add the remaining elements.

9b71709cb8 intel/decoder: Fix is_header_field starting condition.
Starting positions >= 32 are not part of the header, rather than >.

Caught by Coverity, which found that "bits <<= field->start" may shift
by 32, which has undefined behavior.

d5bd0e411e intel/gen_decoder: return -1 for unknown command formats
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.

e8d9b76f63 intel: tools: add aubinator_error_decode tool
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)

471c1bc7cc aubinator/gen_decoder/i965: decode instructions from dword 0
Some packets like 3DSTATE_VF_STATISTICS, 3DSTATE_DRAWING_RECTANGLE,
3DPRIMITIVE, PIPELINE_SELECT, etc... have configurable fields in
dword0, we probably want to print those.

0f83c05149 intel: genxml: compress all gen files into one
Combining all the files into a single string didn't make any
difference in the size of the aubinator binary.

With this change we now also embed gen4/4.5/5 descriptions, which
increases the aubinator size by ~16Kb.

v2 (Lionel): rebase makefiles

This way they become part of libintel_common.la so I can use them in
the i965 driver.
