ad9bd2f40a Avoid creating an out-of-bounds pointer in word() (#48) 
As it is never dereferenced in the n == -1 case it shouldn't cause any
problems. However, UBSAN complains about this, so it is required to run
the tests when compiling with -fsanitize=undefined.

cbf924342b Fix out-of-bounds access in gototab array for caret character (#47) 
When matching a caret, the expression	`f->gototab[s][c] = f->curstat;` in
cgoto() will index the 2D-array gototab with [s][261]. However, gototab
is declared as being of size [NSTATES][NCHARS], so [32][259]. Therefore,
this assignment will write to the state for character 0x1.
I'm not sure how to create a regression test for this, but increasing the
array size to HAT+1 values fixes the error and the tests still pass.

I found this issue while running awk on a CHERI system with sub-object
protection enabled. On x86, this can be reproduced by compiling awk
with -fsanitize=undefined.

5b602ca8a2 Add support for "\a" and "\v" to regex and command line args (#44) 
Support POSIX-specified C-style escape sequences "\a" (alarm)
and "\v" (vertical tab) in command line arguments and regular
expressions, further to the support for them in strings added on
Apr 9, 1989. These now no longer match as literal "a" and "v"
characters (as they don't on gawk and mawk).

IOW, lex.c already supported these (lines 390-391 as of 4e343460);
the support needed to be added to b.c and tran.c.

Relevant POSIX reference:

Don't display empty error context.

Context extraction didn't handle this case and showed uninitialized memory.

c70b9fe882 awk: Use random(3) instead of rand(3) 
While none of them is considered even near to cryptographic
level, random(3) is a better random generator than rand(3).

Use random(3) for awk as is done in other systems.

Thanks to Chenguang Li for discussing this in the lists
and submitting the patch upstream.

cc165f4be9 maketab: support build systems with read-only source. 
If your generated files are considered outputs that live elsewhere, you
need a way to tell maketab where ytab.h actually is.

Specifically, I'm trying to avoid checking in generated files in
Android's AOSP tree's copy of one-true-awk.
