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

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.

Replace {0} initializers with {}, since it is equivalent and simpler
(and avoids the warning).

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.

Like sprintf() with automatic buffer allocation.
This should help to avoid fixed-size buffers in
non-performance-sensitive code that formats strings.

Move dependency includes into a new spdk.deps.mk file,
then include it at the end of Makefiles that build
source files.
Also add a test to autobuild.sh to confirm that
binaries are regenerated if we make after touching a
header file.

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.
