i965 wants to use an offset from a base because everything is in a
single buffer whose address may be relocated, and all base addresses
are set to the start of that buffer.
iris wants to use a full 64-bit address, because state lives in separate
buffers which may be in the shader, surface, and dynamic memory zones,
where addresses grow downward from the top of a 4GB zone, So it's very
possible for a 32-bit offset to exist relative to multiple bases,
leading to the wrong state size.

While this format isn't listed in BSpec: 53911, other documentation and
empirical evidence suggest that it's fine to remap it to R32_FLOAT. I've
filed a bug for the BSpec page.

Rename the original device info initialization routine so callers
don't mistakenly call the wrong one:
gen_get_device_info_from_fd:
Queries kernel for full device info, including topology
details.
gen_get_device_info_from_pci_id:
Partially initializes device info based on PCI ID lookup, when
the kernel is not available.

i965 links against libdrm for drmIoctl, but anv and iris both
re-implement this routine to avoid the dependency.
intel/dev also needs an ioctl wrapper, so lets share the same
implementation everywhere.

We might want to resolve something to be in a particular register,

We currently use the group->next pointer to iterate through the <group>
tags. This change them to be a type of field, so we can descend into
them while iterating, and then go back to the original position. Will be
useful when we want to decode <group>'s inside <group>'s, and when there
are more <field>'s after a <group> tag.

A gen_group (group in most of the code) can be of several types:
- instruction
- struct
- register
- group (?!?)
The <group> tag actually represents an array of elements. So at least
in our code, lets call it an array to avoid confusion with gen_group.

When using gen_spec_load_from path, only abort decoding if the read
length is 0. Previously, we were aborting if finding an EOF, even if
something was read from the file.
Also only kill the decoded file if no commands or structs were found,
and print a message in such case.

IGT has a test to hang the GPU that works by having a batch buffer
jump back into itself, trigger an infinite loop on the command stream.
As our implementation of the decoding is "perfectly" mimicking the
hardware, our decoder also "hangs". This change limits the number of
batch buffer we'll decode before we bail to 100.
