Exported lib/bdev/rte_virtio as a separate
library not dependent on bdev.
Virtio is now accessible via spdk_internal/virtio.h.
The header is marked `internal`, as it's
not meant to be used by end users. It's
not handy to handle all backend-specific
(e.g. Virtio-SCSI) logic in a user code.
For now the Virtio interface is publicly
exposed only via bdev_virtio module. We
might want to consider adding a separate,
public Virtio-SCSI library in the future.
Note: this patch doesn't do any changes
to the virtio code. Everything is

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.

Resolve relative paths before using them to clean up command lines.
This should also help shorten the overall command line length that gets

Since the individual build steps include the path now, the subdirectory
printouts are less useful (especially with parallel make, where output

The normal CU_ASSERT_FATAL macro calls a function that is not marked as
noreturn, so static analyzers (e.g. scan-buid) can't figure out that
fatal asserts are really fatal.
Add a wrapper macro that calls abort(), which the analyzer can determine
does not return.

Modern GCC and Clang versions can generate .d files without needing the
complex sequence of sed scripts that we currently use.
Also adjust the .o rule so the .d file is regenerated if it gets
deleted.
Also make the .o depend on all of the Makefile fragments in
$(MAKEFILE_LIST) so that it is rebuilt if the Makefile is changed.
