description:
Introduce dynamic registration of info files in PLIST.

For each file listed in INFO_FILES the installed files matching
${PREFIX}/${INFO_DIR}/filename(-[0-9]+)? are registered as belonging
to the package.

Also ignore the same files in print-PLIST target.

Info files should not be listed in PLIST files anymore but the awk code
snippet (_PLIST_AWK_INFO) in charge of actually dealing with info files for
the plist target will strip any it finds in them.

Now for the reason behind this...

Older makeinfo command (before pre-release version 4.5.90 or before release
version 4.6) had SPLIT_SIZE_THRESHOLD: when an info file size was
>= SPLIT_SIZE_THRESHOLD then the info file was split in chunks of
DEFAULT_SPLIT_SIZE size.

DEFAULT_SPLIT_SIZE in older versions of makeinfo was 50000 (bytes)
and SPLIT_SIZE_THRESHOLD was 70000.

So if an info file has a size < 70000 and is processed by makeinfo < 4.6
it is not split in chunks. But if it is processed by makeinfo >= 4.6
texinfo.mk to emulate older version automatically adds `--split-size=50000'
to makeinfo's command line and this time the info file is split in chunks...

This can lead to PLIST inconsistency from platform to platform or more
exactly from version to version of makeinfo.

Now we don't have to care about this problem and the info files removal
from PLIST files can happen.
