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.

e8fe9f9635 awk: allow printf('%c') to output NUL, closes 13486
Treat the output of printf as binary rather than a null-terminated
string so that NUL characters can be output.

This is considered to be a GNU extension, though it's also available
in mawk and FreeBSD's awk.

1. Replacing source/dest with uh_sport/uh_dport. It seems that uh_* members are
   defined on both Linux and BSD, so no #ifdef here
2. Use SOL_IPV6 instead of SOL_RAW on the FreeBSD to fix IPV6_CHECKSUM setsockopt
