80d14beae9 Rename two config options:
FEATURE_SH_STANDALONE_SHELL => FEATURE_SH_STANDALONE
FEATURE_EXEC_PREFER_APPLETS => FEATURE_PREFER_APPLETS
Make SH_STANDALONE depend on PREFER_APPLETS.

07c394e69b - mv ip*_main into ip.c; use a dispatcher to save on needless duplication.
Saves a minor 12b.

e87d7955f8 - rewrite the ip applet to be less bloaty
- mark libiproute's matches() as deprecated. Convert to index_in_(sub)str_array()!
   text    data     bss     dec     hex filename
    314       0       0     314     13a ip.o.orig
    200       0       0     200      c8 ip.o
Using a smallint for the key would save another byte.

c44ab01b75 Improve STANDALONE_SHELL. "safe" applets are renamed NOEXEC applets
and now this fact is recorded in applets.h, not ash.c.

./busybox ash -c 'i=20000; while test $i != 0; do touch z; i=$((i-1)); done'
runs more than twice as fast with STANDALONE_SHELL versus without.
