Each device can have its own vamgr, so make it per device now.
This can fix the failure with multiple GPUs used in one single
process.
v2: rebase

The AMDGPU_VA_RANGE_32_BIT flag is added to request VA range in the
32bit address space for amdgpu_va_range_alloc.
The 32bit address space is reserved at initialization time, and managed
with a separate VAMGR as part of the global VAMGR. And if no enough VA
space available in range above 4GB, this reserved range can be used as
fallback.
v2: add comment for AMDGPU_VA_RANGE_32_BIT, and add vamgr to va_range
v3: rebase to Emil's drm_private series
v4: fix one warning

The amdgpu_device for a device node needs its own dup'ed fd, instead
of using the original fd passed in for a screen, to make multi-x-screen
ZaphodHeads configurations work on amdgpu.
The original fd's lifetime differs from that of the amdgpu_device, and from the
one stored in the hash. The hash key is the fd, and in order to compare hash
entries we fstat them, so the fd must be around for as long as the amdgpu_device
is.
This patch for libdrm/amdgpu is a translation of the radeon-winsys ZaphodHeads
fix for mesa's radeon-winsys, from mesa commit 28dda47ae4d974e3e032d60e8e0965c8c068c6d8
"winsys/radeon: Use dup fd as key in drm-winsys hash table to fix ZaphodHeads."

v2: Check for valid fd's being >= 0, because fd == 0 is in theory
a valid, although unlikely, fd and fd == -1 would denote an
invalid fd. Thanks to William Lewis for pointing this out.

This is the first sub-patch of va interface task, the va task is
about adding more va management interfaces for UMD, by design, the
vamgr should be per-process rather than per-device.

Instead of taking a look at the device major/minor we
just compare the primary device name to figure out if
two fds are pointing to the same device.
