45cab335bc include: move standard includes into spdk/stdinc.h
This is the first step toward isolating standard C and POSIX headers
into a single replaceable header file.

13f8cf1536 nvme: add NVME_QUIRK_DELAY_AFTER_QUEUE_ALLOC
The VirtualBox emulated NVMe device will intermittently
hang on the first read/write command after an I/O
qpair has been allocated.  The frequency of the hang
diminishes if a delay is added after allocating the I/O
qpair - until it disappears completely with a 100us delay.
So add a quirk to insert this delay.

Note - the 100us delay was tested by running
the hello_world example app 50000 times.

implementation of I/OAT.

8bf37ee769 nvme: change nvme_intel.c to nvme_quirks.c
Make the quirks mechanism generic in preparation for quirks for devices
from other vendors.

6b1e4e732d Drop libpciaccess and switch to DPDK PCI
This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.

Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

For existing \file markers, move them to the top of the header and tweak
the wording for consistency.

04adec22bc Add extern "C" wrapper to all public headers
Also consistently place the extern "C" before any includes or other
declarations in files that already had it.

7672976a6a nvme: move class code to pci_ids.h
Move toward collecting PCI IDs, class codes, etc. in pci_ids.h instead
of individual device-specific headers.

87844a30ef nvme: move struct pci_id into nvme_internal.h
This doesn't need to be part of the public API. It is only used by the
NVMe quirk lookup tables.

aa2970b9f3 nvme: Add Intel NVMe device supported feature quirks
This patch adds Intel NVMe device list and overrides the
supported log pages according to the quirk list.

In particular, the READ_CMD_LATENCY and WRITE_CMD_LATENCY pages are
supported on Intel DC P3x00 devices despite not being listed in the
Intel vendor-specific log page directory.

c02b179490 Remove year from copyright headers.
Also add a space between Copyright and (c).

The copyright year can be determined using git metadata.

Also remove the duplicated "All rights reserved." - every instance of
this line already has a corresponding "All rights reserved" immediately
below it, except for examples/ioat/kperf/kmod/dma_perf.c, where I have
added it manually.

Performed using this command:

git ls-files | xargs sed -i -e 's/Copyright(c) \(.*\) Intel Corporation. All rights reserved./Copyright (c) Intel Corporation./'
