[PATCH v4 0/3] docs: Document list of undocumented commands

[Hans Ulrich Niedermann]

This patchset adds a script to the buildsystem which determines
the lists of GRUB commands implemented in the source code and
the list of GRUB commands documented in grub.info and documents
the differences.

For that matter, the script will autogenerate a list of the
undocumented commands to be included in grub.info, so that the
undocumented commands are at least listed there so users have
a point to start researching. If the command is at least
mentioned somewhere withing grub.texi, that will be noted.

The two commands pxe_unload and uppermem which were documented
in grub.info but not implemented in the source code are removed
from grub.texi in separate patches in the patchset.

The long term goal of this is to reduce the number of undocumented
GRUB commands to zero and to keep it there.

For conflict free merging, this patchset requires my gitignore
patchset as it adds a gitignore pattern for the file it generates.
