lib/bb/shell.py: drop

Browse Source 
This was removed in the bitbake repository back in 2010 (bitbake
revision 24857e2ceb405916b0b0b3e75c6c2375a909b9ba) - it's not clear
to me what happened, but for some reason the file remained in the poky
repository. However it does not appear that it has been used since then
and the reasons for removing even more valid now than they were then -
the code has moved on even further, we have memory resident bitbake
server, and if we were to re-implement this we would do it in a
different way. Drop the file and bring us back in sync with the bitbake
repo.

"""
BitBake Shell
IDEAS:
* list defined tasks per package
* list classes
* toggle force
* command to reparse just one (or more) bbfile(s)
* automatic check if reparsing is necessary (inotify?)
* frontend for bb file manipulation
* more shell-like features:
- output control, i.e. pipe output into grep, sort, etc.
- job control, i.e. bring running commands into background and foreground
* start parsing in background right after startup
* ncurses interface
PROBLEMS:
* force doesn't always work
* readline completion for commands with more than one parameters
