6bdfbc4cb5 libbb: fix '--help' handling in FEATURE_SH_NOFORK=y 
Most BusyBox applets respond to the '--help' option by printing
a usage message.  This is normally handled by busybox_main() so
applet main routines don't have support for '--help'.

In standalone shell mode with FEATURE_SH_NOFORK enabled nofork
applets are invoked directly, bypassing busybox_main().  This
results in inconsistent handling of '--help':

- applets which call getopt() report "unrecognized option '--help'"
  and print help anyway;

- realpath says "--help: No such file or directory" and doesn't
  print help;

- usleep says "invalid number '--help'" and doesn't print help.

Avoid inconsistency by checking for '--help' in run_nofork_applet().

Bug found by Ron Yorston.

6ad38d66d0 libbb: code shrink fgets_str 
Use a NULL value of maxsz_p to indicate to xmalloc_fgets_internal()

This allows the default maximum size to be set once in
xmalloc_fgets_internal() instead of separately in each caller.

bcf91d2760 libbb: code shrink and speed up index_in_strings() 
Rewrite index_in_strings() to replace calls to strcmp()/strlen().
With this change searching for valid names in the applet_names
array (for example) is 40% faster.

The code has to assume the strings aren't sorted, so will always scan
the entire array when presented with an invalid name.

59120c3303 libbb: code shrink and speed up find_applet_by_name() 
find_applet_by_name() determines the appropriate range of applet
indices to check for the given name and performs a linear search in
applet_names[].

Revise the code so the index of the upper bound of the range, 'max',
isn't calculated.  Instead check the value of the first non-matching
character to see if we've reached the end of the range.

This new code speeds up the time to find a valid applet name by 6%
and halves the time to detect that a given name is invalid.  The
average time to detect an invalid name is now the same as for a valid
one.
