Haswell added the ability to inject errors which is extremely useful for
testing. Add two arguments to the tool to inject, and uninject.

Haswell GT3 adds a new slice which is kept distinct from the old
register interface. Plumb it into the code, though it's only 1 slice
still.

Add a new command line argument to the tool which will spit out various
parameters for the giving hardware. As a result of this, some new
defines are added to help with the various info.

Add new command line arguments in addition to supporting the old
features. This patch only introduces one feature, the -e argument to
enable a specific row/bank/subbank. Previously you could only enable
all. Otherwise, it has what you expect (we prefer -r -b -s for
specifying the row/bank/subbank).

Ben Widawsky suggested to use vasprintf, which perfectly fits the bill.
Also fix the logic conversion bug in tests/gem_storedw_batches_loop that
crept in again :(

igt runs under the assumption that nothing else (besides maybe fbcon)
is using the gpu. So we should be able to use all fences.
Keep the conservative testcase around though in case someone has a
broken setup.

For Haswell, some audio configuration registers have changed their name and
some bit definitions.
This patch applies the changes, and uses subfunctions to parse registers for
code reuse.
Here is the name change list:
Audio configuration: AUD_CONFIG_x to AUD_TCx_CONFIG
Audio Misc Control: AUD_MISC_CTRL_x to AUD_Cn_MISC_CTRL
Audio M & CTS programming enable: AUD_CTS_ENABLE_x to AUD_TCx_M_CTS_ENABLE
Audio EDID data block: AUD_HDMIW_HDMIEDID_x to AUD_TCx_EDID_DATA
Audio Widget Data Island Packet: AUD_HDMIW_INFOFR_x to AUD_TCx_AUD_INFOFR
Audio Pipe and Converter Configs: AUD_PORT_EN_HD_CFG to AUD_PIPE_CONV_CFG
Audio Digital Converter: AUD_OUT_DIG_CNVT_x to AUD_Cn_DIG_CNVT
Audio Stream Descriptor Format: AUD_OUT_STR_DESC_x to AUD_Cn_STR_DESC
Audio Connect List Entry & Length: AUD_PINW_CONNLNG_LIST_x to
AUD_TCx_PIN_PIPE_CONN_ENTRY_LNGTH
Audio Connection Select Control: AUD_PINW_CONNLNG_SEL to AUD_PIPE_CONN_SEL_CTRL
Audio DIP & ELD Control State: AUD_DIP_ELD_CTRL_ST_x to AUD_TCx_DIP_ELD_CTRL_ST
Audio HDMI FIFO status: AUD_HDMIW_STATUS to AUD_HDMI_FIFO_STATUS
NOTE:
For Tx, x = A/B/C, meaning Transcoder A/B/C.
For Cn, n = 1/2/3, meaning audio converter 1/2/3.

This patch makes the file to follow kernel coding style:
- replace leading spaces with tabs for alignment
- fix some minor format issues
But the max length of a line is set to 120 characters for readability

The PCH transcoder config register (PCH_TRANS_CONF, 0xf0008) is not the
correct config register for transcoder A, B or C. This register is in
PCH and for CRT display, nothing to do with display audio.
So This patch removes misuse of it as config register for transcoder A/B/C.

Whatever the reason (and I've thought there isn't one) if we fork and
kill right away the child seems to not reliably die. We can work
around this little race by forcing the default SIGQUIT handler. This
should break anything since we reset our atexit handling anyway, so if
the helper needs any atexit handling the special signal helpers will
be reinstated.
Note that inserting sufficient amounts of printf between the fork and
kill makes this unnecessary.
While add it also add the retry loop for the waitpid call, in case
there's another guy constantly interrupting us.

If we're really fast we've trying to stop the signal helper again
we somehow race somewhere and it'll never happen. So add a testcase for
this. Since I expect more to come for testsuite tests add a separate
make target for them. Run tests with
$ make check

The simulator doesn't like this nor really support it :(
v2: We've tried to a more gentle resume testing using the pm_test
infrastructure, but that alos failed. So add a FIXME comment that we
need to improve things a bit here.

Our kernel likes to occasionally kill process with a SIGBUS when this
shouldn't ever happen. Hence also handle this signal in the exit
handler infrastructure.
