How to update .patchset files for HaikuPorter recipes, when they do not apply cleanly.

Updating HaikuPorter .recipes (and what to do when applying the .patchset fails).

An example-based, step-by-step guide.

TL;DR

> git am <foobar.patchset>
> git apply --verbose --reject .git/rebase-apply/<FAILED_PATCH_NUMBER>
> <edit files as needed here, look for .rej files to know what need manual intervention>

Proof of concept for `pkgman search --not-required`.
The idea is *very* simple.
- Get the list of installed packages.
- From that, builds a list of all unique requirements.
- Print the list of packages that do not provide any of those requirements.

CUE splitter using ffmpeg (to mp3)
# Changes over the original:
#
# + Support both Python 2 & 3.
# * fixed location of bitrate parameters.
# * Fixed track duration so it does't cuts tracks short, nor starts them early
# (Margin of error for .flac source files should at most be around +/- 0.013 secs).
# + Added pre_gap support.
