Simplify the build rules so that common libraries are always linked.
Also fix up a couple of -lpciaccess instances that should have been
changed to $(PCIACCESS_LIB).

vtophys() was checking for out-of-range addresses incorrectly: vfn_2mb
is already shifted to account for 2 MB hugepages, but it was being
compared with a mask that did not account for the shift. This would
allow out-of-bounds access to the 128tb map array for certain invalid
addresses (it had no effect on addresses within the valid userspace
range).

Other subsystems can depend on this one and then use
SPDK_RPC_REGISTER to register RPC functions.

Since we used u64 to mask CPU cores, the available number of CPU
is 64, for default RTE_MAX_LCORE in DPDK, the value is 128, in some
cases(e.g.: when nr_io_queues > 4) we can get the wrong lcore ID.

A transfer using less than the total bounce buffer size is a normal
occurrence and not worthy of a tracelog. Also drop the pointless
conditional.

Avoid using the RDMA-specific tx_desc when the transport-agnostic

Should set tx_desc=NULL here. If not,When
nvmf_post_rdma_recv(conn, rx_desc) fails,
we would make tx_desc deactive again, and
this is wrong.

The section is really defining a subsystem as defined
by the NVMf specification. There does not appear to be
any need for a group of subsystems.
This change only updates the configuration file. It does
not remove all references to a subsystem group from
the code.

The specification refers to this concept as a Host,
so use that term. This only changes the configuration
file usage. Initiator groups are still referenced in
the code and will be removed later.

All source files will now depend on config.h, which is generated based
on the defaults in CONFIG and the command line arguments passed to make.
This ensures that any configuration changes, including on the command
line, cause a full rebuild.
