8f894c94b7 fnematch: fix out-of-bounds access on EOF 
fnematch() expects to store a NUL byte when EOF is encountered.
However, the rewrite broke this assumption because r.len from getrune()
is zero on EOF.  This results in j becoming negative on EOF, causing an
out-of-bounds access.  It is simplest to just force r.len to 1 on EOF
to copy a single NUL byte--the rune is initialized to zero even for EOF.

This also fixes the call to adjbuf().  We cannot use 'k' to determine
when we need to expand the buffer now that we are potentially reading
more than a single byte at a time.

52154eb4e7 Correctly reset the goto table for a state. 
We cannot use set_gototab() to reset all the entries for a state,
it will leave existing entries as-is.  Add a new reset_gototab()
function that zeroes the table entries for the specified state.
There is no need to reset the goto table immediately after
resize_state(), it is already initialized via calloc().

4d617ba111 Fix a potential out-of-bounds read caused by the big-endian fix. 
We must store a UTF-32 empty string, not UTF-8 empty string, for
an empty CCL.  Found running the awk test suite with address sanitizer.

c35264f991 Disable utf-8 for non-multibyte locales, such as C or POSIX. 
This makes it possible to get the old awk behavior (where chars are
bytes) by setting LC_CTYPE to C or POSIX.  OK schwarze@

ff3903525f Fix size computation in replace_repeat() for special_case REPEAT_WITH_Q. 
This resulted in the NUL terminator being written to the end of the
buffer which was not the same as the end of the string.  That in
turn caused garbage bytes from malloc() to be processed.  Also
change the NUL termination to be less error prone by writing the
NUL immediately after the last byte copied.  OK sthen@

Prevents strings beginning with "inf" or "nan" from being interpreted
as infinity or not-a-number respectively which still parsing "inf"
