The new section documents the maintainership status for the various
FFmpeg releases, on a best effort basis.

FFmpeg never had distinct alfa/beta 0.7 releases, so having a single
0.8 section with all the changes should be less confusing for the
users, and it is also consistent with what we did with 0.5 and 0.6
releases.

Also add a dedicated 0.7 section, explaining how it differs from 0.8.

This reverts commit bb524924.
This is necessary to allow running "make" in subdirs again.

This helps catching cases where the format string doesn't
match what is passed in, or injection bugs where user data
is passed in as format string.

This eliminates a warning about a set-but-unused variable.

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.

Show the invalid string in the error message.

While at it also prefer "Could not" over "Couldn't", plain forms are
preferred over contractions (simplify readability, especially for non
English-savvy people).

This avoid a crash with in avfilter_merge_formats() in case one of the
filter formats list has multiple time the same entry.

Thanks to Mina Nagy Zaki for helping figuring out the issue.
