cfc88a45d0 nvme/perf: capture master lcore return code
Previously, if the work function on the master lcore failed, the perf
program would still return with a successful exit code.

a900f9ac9a nvme/perf: check nvme_register_io_thread() status
Do not continue running the thread work function if that thread could
not get an I/O queue.

70db0e1c08 nvme/perf: Add support for multiple cores per device.
Intelligently allocate cores and devices to handle
the following cases:

1) Equal cores and devices
2) More cores than devices by using multiple cores per device
3) More devices than cores by using multiple devices from a single core

8307eb5f55 build: enable missing function declaration warning
This helps weed out functions that should be static, functions that are
not declared in public header files, and .c files that don't include
their .h interface headers.

f79a334e33 build: fix old-style declaration warnings
Fix all of the uses of __thread so they are at the beginning (similar to
e.g. static).

Don't actually enable -Wold-style-declaration, since clang doesn't
understand that.

This allows comparing the Linux kernel driver's performance to the SPDK
user-mode NVMe driver.

92da744700 util: add sprintf_alloc() function
Like sprintf() with automatic buffer allocation.

This should help to avoid fixed-size buffers in
non-performance-sensitive code that formats strings.

4ba47234f3 Add pci_device_has_non_null_driver().
This helps enable FreeBSD, where pciaccess pci_device_has_kernel_driver()
is not functional.  The function will return 0 if there is no driver
attached, or the Linux uio or FreeBSD nic_uio driver is attached.  It will
return 1 otherwise.
