More consistent with the rest of the build system, and more compact.

The option chapter is based on the avoptions_codec.texi auto-generated
file.

Documentation includes only the externally visible API of the installed
headers.

Based on a patch by Anton Khirnov <anton@khirnov.net>.

Consistent with --enable-doc, and easier to type.

Allow to select specific documentation components, and reliably check for
component dependencies.

In particular, check for perl presence on the system.

Do not rely on shebang directive in the script, whose exact behavior is
system dependent.

There is no much point into splitting documentation for filters. Also
having a separate document for a library is inconsistent.

The $(dir) function used to construct OBJDIRS includes a trailing slash
in the names returned, which GNU make 3.82 does not match to the
slash-less 'doc' in the documentation dependencies, causing parallel
build to fail.  Adding a slash fixes this and still works with make
3.81.

Now that a documentation generator is built in the doc directory,
this is no longer necessary.  Fixes the Make warning:
Makefile:188: target `doc' given more than once in the same rule.

This fixes doc generation in build tree separate from source.

Setting SRC_PATH to "." when building in-tree removes the need
for a quoted version of the source path since out-of-tree builds
are not possible if the pathname contains spaces.
