8b81801e2d env_dpdk: do rte_eal_cleanup() at process exit
We already use destructor functions in env_dpdk to do
some cleanup at process exit, so let's also add one
to call rte_eal_cleanup.  This ensures all hugepage
files are freed before the process exits.

Fixes issue #2267.

2b65309b6c env: remove spdk_pci_get_[first|next]_device
These APIs are not safe, since they do not hold the
pci device lock across calls, which can cause problems
if a device is inserted or removed while handles
returned by these APIs are being used.

13fbf8851e env: add spdk_pci_for_each_device
This is a safer alternative to spdk_pci_get_first/next_device,
since those APIs do not hold the lock between calls.

Future patches will remove those APIs, and change callers to
use this new API instead.

f111b320f0 lib/env_dpdk: remove duplicate entries from DPDK_LIB_LIST
Future patches will remove some of the more complex conditions
between different configure flags. As a result duplicate entries
might be present in DPDK_LIB_LIST.

Just for tidiness of the DPDK linker args, the DPDK_LIB_LIST_SORTED
is added. Using sort function removes duplicate entries in the list.

2e7250a669 lib/env_dpdk: remove path for handling DPDK earlier than 20.11
SPDK supports only maintained LTS versions of DPDK.
For SPDK 22.01 this means DPDK 20.11 and 21.11.

This patch removes paths for earlier versions of DPDK.
There is no need to check if library is present for the following:
- rte_telemetry was added as rte_eal dependency in DPDK 20.05
- rte_kvargs was added as rte_eal dependency in DPDK 18.08
- rte_pmd_aesni_mb, rte_pmd_isal, rte_pmd_qat were removed in DPDK 20.11

d1522dd5bc Revert "env/dpdk: Exclude the orig cpuset in spdk_unaffinitize_thread"
This reverts commit d9561c444f.

This patch is incorrectly iterating the CPU mask assuming it is
contiguous. However, rather than fix it, let's just let the kernel
scheduler place the thread where it thinks is best. It's going to prefer
idle cores anyway. So reverting is the simplest way forward.

This patch revert commit 8f7d9ec.  In function vtophys_iommu_init(), we
can use `dev->drvier` in RTE_DEV_FOREACH() loop to count number of devices
probed by device driver using vfio APIs, or we will count all the PCI devices
that bind to vfio-pci driver, only the probed device's IOMMU group is added
to vfio container.

The original implementation is correct to count `g_vfio.device_ref` in
vtophys_pci_device_added(), we don't need to count it in
vtophys_iommu_device_event() callback.

Fix issue #2086.

c4fafdb215 env: only pass failing address to spdk_pci_error_handler
siginfo_t is a GNU extension.  SPDK (and DPDK) have
direct dependencies on GNU extensions, but it's a bit
nicer if external modules don't also need to define
_GNU_SOURCE.  Currently siginfo_t parameter in the
spdk_pci_error_handler is the only thing that violates
this.

Note that DPDK also supports registering sigbus handlers,
but they take the failing address as a parameter instead
of the full siginfo_t structure.  Let's adopt the same
for SPDK.

While here, remove an extra semicolon that was just after
the virtio sigbus handler function signature that was
updated in this patch.

6c75f0a266 env_dpdk: save hotplug timeout timestamps separate from rte_devargs
DPDK recently clarified some semantics on the rte_devargs 'data'
and 'args' fields.  This actually breaks our use of the 'data'
field to store the 2 second timeout timestamp for delaying
attach to newly inserted devices.  Investigating this further,
it does not seem our use of the 'data' field was valid - it just
happened to work until now.

We could use the 'args' field now.  But knowing whether to use
'args' or 'data' would then be dependent on the DPDK version.
We cannot use RTE_VERSION_NUM to decide, because this is a
compile time decision, and it is possible in shared library
use cases that we could actually link and execute against a
different version of DPDK than we built against.

So instead we will create our own env_devargs structure that
will store these allowed_at timestamps. Currently it's just
a linked list (which is exactly how DPDK does it) - we could
make it more optimal with a hash table down the road, but this
code only executes when we are doing PCI enumeration so it is
not performance critical.

Fixes #1904.

5957f2c479 env: extend the use of event listen
struct sockaddr_nl {
    sa_family_t     nl_family;  /* AF_NETLINK */
    unsigned short  nl_pad;     /* Zero */
    pid_t           nl_pid;     /* Port ID */
    __u32           nl_groups;  /* Multicast groups mask */
};

nl_pid is the unicast address of netlink socket.  It's always 0
if the destination is in the kernel.  For a user-space process,
nl_pid is usually the PID of the process owning the destination
socket.  However, nl_pid identifies a netlink socket, not a
process.  If a process owns several netlink sockets, then nl_pid
can be equal to the process ID only for at most one socket.
There are two ways to assign nl_pid to a netlink socket.  If the
application sets nl_pid before calling bind(), then it is up to
the application to make sure that nl_pid is unique.  If the
application sets it to 0, the kernel takes care of assigning it.
The kernel assigns the process ID to the first netlink socket the
process opens and assigns a unique nl_pid to every netlink socket
that the process subsequently creates.

e4070ee0e0 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

79f9a7f572 build: generate pkg-config files for SPDK
Users can now generate the necessary linker args for their
own applications using something like:

PKG_CONFIG_PATH=build/lib/pkgconfig pkg-config --libs spdk_nvme

Dependencies between libraries are included in the generated
.pc files, so the user only needs to pass the top-level subsystems
or individual SPDK libraries they are using in their application.

Modules will automatically be added to the output if the associated
library is specified.  For example, specifying "spdk_bdev" will include
the libraries not only for spdk_bdev, but also all of the bdev modules.

Users still need to supply the -Wl,--no-as-needed or -Wl,--whole-archive
flags. They cannot be added to the .pc files without increasing the length
of the argument string by a factor of 15x to 20x.

Modify the test/external_code/hello_world Makefile to use pkg-config to
ensure this gets tested at some level in our autotest environment.

b8c99a3aad lib: Use PRId64 for portability
POSIX defines PRId64/PRIu64/PRIx64 for printing 64-bit values in a
portable way. Replace a few references to %ld to remove the assumption
about the size of a long. Similarly, use %z with size_t arguments.

Where the value being printed is an unsigned 64-bit value, use PRIu64
instead of %ld.

Explicitly test for not __linux__ where that is the intent, rather
than testing for __FreeBSD__.

Cast pointer to uintptr_t before aligning it, rather than using
a specific integer size which may not be large enough to store a
pointer.
