CONFIG_* defines

[Vladimir N. Oleynik]

Hi, all.

The Busybox has an old problem.
after any usage make config, may be change FEATURE_* only
1) recompiling applets/* always, but may be not require
2) do not recompile applets, used this feature

My idea:
1) use namespace as "[A-Z]+_[A-Z]+=y" for applet`s name only
2) for features use namespace as:
2a) for global feature
"BB_FEATURE_NAME"
2b) for one applet
"APPLET_FEATURE_NAME"

or any English-like namespace with 3 or many "_", help me with this.

After such changes, can be write an internal configurator will much easier.
(sh+grep+uniq + rm applet.o)
