Summary:                    support NUL input bytes in awk
Description: 
Currently awk breaks when givin a NUL input byte because it uses strchr()
to find the end of a record. Since the NUL's hide the newlines, the record
buffer grows until awk runs out of memory.  Using memchr instead avoids
this problem.

Additionally, pattern matches fail with embeded NUL's because regexec()
uses a NUL-terminated string.  The best we can do to avoid this is treat
NUL as a record seperator.

Behavior with NUL's is left undefined by SUSv3, but I believe this is the
most useful implementation.
