- Fix issue in Doxy dependency check when nothing needs to be installed.
'set -e' and plain '[]' logic don't mix well.
- Fix Makefile snafu when building Doxy output for a single file.
- Include only one of vnet/vnet/buffer.c/dpdk_buffer.c in docs depending on
DPDKness. This could do with some improvement in future, eg to properly
align the pre-doxy steps with what Doxy does.
- Fix rendering of 'inline' tag in Doxygen by having it interpret
always_inline as "inline static".
- Bunch of duplicate CLI command structure names that confused docs and may
one day have caused debugging issues.
- Several other Doxygen syntax issues fixed, like documenting non-existant
parameters (usually just the wrong parameter name, typos, etc)
