When the --werror meson build option is set, we can pass the "-W",
warning-as-errors, flag to sphinx to get the same behaviour for doc
building as for building the rest of DPDK. This can help catch
documentation errors sooner in the development process.

To see only errors and warnings from the doc builds, we can send the
standard output text to a logfile and have only the stderr messages
printed. This is similar to what is done for the API documentation.

When building the DPDK guide documents, the DPDK version information was
pulled using "make showversion", which meant there was a dependency on
the DPDK make-based build system. Change this to have the version info
passed in from meson itself.

When sphinx-build reports its version information to stderr rather
than stdout, the wrapper script misses it, and then fails to run.
We can fix this by redirecting stderr to stdout for the version
query call.

Add proper support for calling sphinx whenever a file in the doc
directory changes. This is accomplished by using a wrapper script
for sphinx, which runs sphinx but also emits a gcc-format dependency
file listing all the doc files. This is used by ninja so that any
change to the doc files triggers a rebuild of the docs.
